What if Earth had Rings like Saturn? | #aumsum #kids #science #education #children
Earth would have rings if a celestial body like moon or comet gets too close to it and exceeds the Roche limit. It will get ripped apart into pieces, thus forming its rings.
First of all, Earth would look spectacular. Secondly, selfies might be called Ringies as people will start taking selfies with rings as a backdrop. Thirdly, nights would be much brighter than they are now. This is because the rings would be much closer than the moon and also much more spread apart, thus reflecting much more light. Fourthly, weather patterns or atmospheric composition might change depending upon what the rings are made up of. Saturn's rings are made of billions of particles of ice, rocks and dust. Lastly, they would surely top the world's best tourist destination list.
Why doesnt Earth have Rings like Saturn? | #aumsum #kids #science #education #children
The rings of Saturn can be remnants of a moon, comet, etc., that got ripped apart due to Saturn’s gravitational pull, or result of a large collision between two moons. Some even claim that rings are made up of debris left over during the formation of our solar system.
So, how did this debris form Saturn’s rings?
It’s got to do with Roche limit. It is the distance at which objects tend to be ripped apart by the planet’s gravitational pull. In case of Saturn, it is popularly believed that a celestial body like moon or comet got too close to it and exceeded the Roche limit. Hence, it got ripped apart into pieces, thus forming its rings.
Now, earth also has a moon. But since it is beyond the Roche limit, it doesn’t get ripped apart into pieces to form rings.
What if Earth Doubled in Size? | #aumsum #kids #science #education #children
Diameter of earth would increase from 8,000 miles to 16,000 miles. If the density of earth remains same, then its mass will increase 8-fold. Earth's gravity will naturally double. This will have major consequences.
Firstly, our weight will double. All the gyms will definitely see increased enrolments. Secondly, our bones will not be able to support our increased weight. Thirdly, our hearts will have to work double hard to make sure blood reaches all the parts of our body. Fourthly, birds, airplanes, choppers will all fall down to the ground. Fifthly, trees will not be able to stand upright. Most of them will fall down. Finally, if we fall down, it will hurt twice as much.
What if the Moon Disappeared? | #aumsum #kids #science #education #children
Firstly, our nights would definitely be darker. Due to this, night predators like owls would find it very difficult to hunt at night. But, this would be great news for stargazers as there is no interference from moonlight. Secondly, as the moon's gravity is no longer there to hold the earth, it would rotate faster and thus, our days will be much shorter than 24 hours. Craters on moon are a proof that it has protected earth from thousands of asteroids and comets, this no longer will be the case.
With the moon missing, tides in our oceans will be much much smaller as only sun will slightly influence them. Changing tides will also influence the global weather patterns. Finally, moon's disappearance might tilt earth's axis drastically, causing extreme changes in seasons and climate.
What if Earth Lost its Atmosphere? | #aumsum #kids #science #education #children
Sound travels to our ears by vibrating air molecules which are present all around us. Now no atmosphere means no air. Hence, there would be complete silence.
Secondly, no atmosphere means no oxygen, life on land would not last for more than 5 minutes. But life inside oceans might continue for some time as fishes will use dissolved oxygen to survive. Eventually even that supply will run out.
Thirdly, no atmosphere means no clouds, our sky would lose its magnificent blue color, it would look just as black as outer space.
Fourthly, unfortunately birds can't fly in vacuum, they will drop down to earth.
Lastly, without any atmosphere, days would be shorter by 4 minutes while nights longer as atmospheric refraction advances sunrise by 2 minutes and delays sunset by 2 minutes.
What if the Earth had 2 Moons? | #aumsum #kids #science #education #children
The most obvious effect of 2 moons would be that our nights would be much much brighter. That would certainly be bad news for stargazers and astronomers.
Also, as you all know that tides on earth are a result of the moon. So, 2 moons would either amplify this effect or cancel out each other. If they were to amplify then we could have huge tides, effectively making living near shorelines almost impossible. But it will definitely be good news for all the surfers.
Finally, as the number of moons increases, so will the number of solar eclipses. Also, hypothetically, if they were to ever collide with each other, then the amount of debris coming out of such collision would make living on earth almost impossible.
What if earth lost Oxygen for 5 seconds? | #aumsum #kids #science #education #children
If it was just 5 seconds, we wouldn’t notice changes in our breathing.
But do you know what would happen around us?
Earth’s crust contains 45% oxygen. Without oxygen, crust would crumble, causing the ground to crumble and we would be in freefall. Buildings, bridges and concrete structure would crumble into dust, as oxygen is the binding agent for concrete. Cars would stop, and planes would fall from sky as their combustion engines wouldn’t work without oxygen. Also, losing oxygen means losing almost 21% air pressure. This would cause our inner ear to explode, causing hearing loss. It would also become darker suddenly.
Do you know why?
For sunlight to reach us, it needs to bounce off air particles like oxygen, dust etc. No oxygen means much fewer particles to bounce off, thus much darker.
What if Earth Stopped Spinning? | #aumsum #kids #science #education #children
The earth spins at a speed of 1000 miles per hour. Its atmosphere also moves along with it at a constant speed. If the earth stops spinning suddenly, the atmosphere would still be in motion, sending everything on the earth’s surface, flying into the atmosphere.
Now, earth’s spinning generates a centrifugal force which is responsible for the huge bulge of water around the equator. No spinning means no centrifugal force. This water would migrate towards the poles, where gravity is the strongest, leaving behind a giant landmass.
Also, remember that, even though the earth stops spinning, it is still revolving around the sun. This means, we would experience a 6 month day, followed by 6 month night. Some experts also believe that earth’s rotation generates its magnetic field. Without rotation, there would be no magnetic field to protect us from the harmful solar winds, making it extremely difficult to survive.
What if the Earth was Cube Shaped? | #aumsum #kids #science #education #children
Earth is spherical in shape because of gravity. Earth's gravity pulls everything equally towards its center and thus gives it a spherical shape
Now, if the earth was cube-shaped, then the following things might have happened.
Firstly, it would look weird.
Secondly, just like gravity, our weight would be different at different places on earth. This is because the 8 corners of the cube would be much further away from the cube's center as compared to the rest of the cube. But this would be good news for people who are over-weight and lazy. Now they can just go to the corners and voila, their weight gets reduced.
Thirdly, due to low gravitational force, the cube corners would have very less atmospheric cover & almost no water, thus rendering them inhospitable.
What if Jupiter Never Existed? | #aumsum #kids #science #education #children
As per Roman Mythology, jupiter is the god of thunder, lightning and storms. It is the largest planet in our solar system and its mass is about 2.5 times the total combined weight of all the other planets in our solar system.
Now, if jupiter would have never existed, it is safe to say that even we would not have existed. This is because some scientists believe that during the initial stages of the formation of our solar system, jupiter's inward migration towards the sun and then subsequent outward migration away from the sun and towards saturn played a vital role in the formation of mercury, venus and earth. Also, since ages jupiter has been protecting earth from collisions with large asteroids and comets. Lastly, more than 70 moons of jupiter would have wandered along the solar system as orphans.
What if Earths Core Cooled Down? | #aumsum #kids #science #education #children
Earth's core temperature is about 10,800 degrees Fahrenheit.
If it cooled down then there would be no earthquakes or volcanoes.
No heat means all the active volcanoes would suddenly become extinct.
Also, earthquakes occur when tectonic plates rub against each other. These plates move because of the intense heat coming from the core. Now, no heat from the core means no movement of tectonic plates, thus no earthquakes.
Scientists believe that earth's heated core plays an important role in the creation of its magnetic field. With no magnetic field, the following things will occur.
Our atmosphere will slowly but surely disappear as there will be no protection from harmful solar winds.
Also, migratory birds would have a very hard time finding their destination.
What if Earth was Flat? | #aumsum #kids #science #education #children
Earth would not remain flat for a long time as gravity will make sure it again pops up into a sphere. Remember, gravity pulls equally from all sides, hence planets are spherical.
Now, if earth was flat and not a sphere, then it would obviously stop rotating. This will lead to the following problems.
Firstly, only revolution around the Sun but no rotation around its axis would mean that Earth will experience a 6-month long day, followed by a 6-month long night.
Secondly, it is believed that rotation of Earth generates its magnetic field. Without rotation, there would be no magnetic field to protect us from the harmful solar winds. Also, it would mean an end to the world-famous lights called Auroras as they are formed due to the interaction between Earth's magnetic field and particles of solar wind.
Why is Pluto not a Planet anymore? | #aumsum #kids #science #education #children
Pluto was discovered by Clyde Tombaugh in 1930. It is not considered a planet anymore because in 2006, astronomers of IAU (International Astronomical Union) gave a new definition to the word 'planet'.
According to the new definition, a planet is a celestial body which is in orbit around the sun, is spherical in shape and it has cleared the neighborhood around its orbit.
What does this mean?
It basically means that using its gravity, a planet should have removed asteroids and dwarf planets, out of its path, thus cleared its neighborhood.
Now, Pluto is in orbit around the sun and is spherical in shape. But since Pluto's neighborhood has many other objects and it has not cleared its neighborhood. It is not called a planet anymore.
What if Sun suddenly became Half its Size? | #aumsum #kids #science #education #children
Firstly, there would be no need of freezers or air conditioners any more. Everything on earth would completely freeze.
Secondly, assuming that earth is still orbiting at the same distance, earth will find itself out of the habitable zone of the Sun, thus slowly but surely wiping out all life on it.
Thirdly, stocks of solar energy companies would completely tank as extremely less sunlight will reach earth's surface.
Fourthly, as there would be extreme scarcity of sunlight, plants in order to perform photosynthesis would probably turn blackish or darkish green in order to absorb as much incident sunlight as possible.
Lastly, as sun's gravitational pull would greatly reduce, outer planets of the solar system, namely Uranus and Neptune may drift away into space.
What if we planted a Trillion Trees? | #aumsum #kids #science #education #children
There are about 3 trillion trees on earth right now. So planting a trillion trees would increase that number by 33%. The impact will definitely be positive for earth as well as all the living things. But this will not immediately solve the climate change problem.
Firstly, freeing up so much land for planting trees seems like a mammoth task. Secondly, these trees would take a number of years to grow big enough to make any meaningful contribution towards reducing carbon dioxide from air. Thirdly, if we do nothing about emissions and keep on adding carbon dioxide to the atmosphere, then by the time trees grow, we would have added more than 1 trillion tons of carbon dioxide, thus nullifying the effects of these trees. So, plantation of trees plus cut in emissions are the need of the hour.
What if Earth started Spinning Backwards? | #aumsum #kids #science #education #children
Backward spinning of the earth is termed as a retrograde motion. Now, to understand the effects of this retrograde motion on earth, scientists performed some simulations.
In these simulations, the first noticeable change was that the direction of winds and oceans currents reversed, causing changes in climatic conditions. This resulted in a much greener earth as the world’s deserts shrank from 42 million square kilometers to 31 million square kilometers.
Secondly, at present, rising level of carbon dioxide is contributing to global warming. But in retrograde world, with more trees to absorb carbon dioxide, the global mean temperature dropped by about 0.2 degrees Celsius, thus considerably lowering the effects of global warming.
Lastly, the rainfall pattern also changed. As a result, the Great Sahara Desert and the Arabian Desert got covered in trees and grasses, while never-seen-before deserts emerged in Southern Brazil and Argentina.
What if you were the Last Person on Earth? | #aumsum #kids #science #education #children
Firstly, you would no doubt be the loneliest person on Earth.
Secondly, there would be no more borders, in fact no more countries anymore. The entire world will yours to roam.
Thirdly, it will be a good thing if you are an animal lover, else you will have a hard time as there will be no one else for company.
Fourthly, fresh food will be extremely hard to come by, but preserved and canned food will last for many a life times.
Fifthly, you will probably forget how to speak in a few years’ time as there would be no human to speak with.
Lastly, you will have to avoid injuries and keep yourself in the best of health as there will be no more doctors to help you out.
What if Rain Disappeared? | #aumsum #kids #science #education #children
Firstly, after the sweltering heat of summer, plants, animals as well as humans are eagerly waiting for those precious drops of water to fall from sky, if rain disappeared, everybody will be mightily disappointed.
Secondly, if rain disappeared, human beings will have to set up huge desalination plants to convert seawater to drinking water.
Thirdly, water will become more expensive than gold, wars maybe fought over it.
Fourthly, if rain disappeared, we will really miss those beautiful rainbows.
Fifthly, if rain disappeared, we may only be able to dream about swimming tanks and long showers.
Lastly, if rain disappeared, fresh water sources like rivers, lakes and even dams will start drying up, fertile lands will turn into deserts, crop production will go down, eventually, even human beings will go extinct.
What if a Black Hole entered our Solar System? | #aumsum #kids #science #education #children
Firstly, Black hole's gravity will cause complete chaos in our Solar System. Orbits of Planets as well as Comets will be significantly altered. Initially comets and meteorites might start hurtling towards us. Later even the planets might start colliding with each other.
Secondly, even if a gigantic planet like Jupiter comes in the path of the Black hole it will be devoured.
Thirdly, if the Black hole comes near Earth, initially its intense gravitational pull will cause devastating earthquakes and volcanoes. When the Black hole reaches our orbit there will be nothing left but an uninhabitable magma-laden rock.
Lastly, our Sun might offer some resistance to start with. A gravitational tug of war might ensue. But eventually even our beloved Sun will be ripped apart to pieces.
What if Cars Disappeared? | #aumsum #kids #science #education #children
What if Cars Disappeared?
Firstly, if cars disappeared, people driving bicycles will be among the happiest.
Secondly, public transportation will suddenly become extremely popular.
Thirdly, millions of cars are sold each year, creating millions of jobs and billions of dollars, if cars disappeared, jobs and money, both will be lost.
Fourthly, billions of liters of petrol and diesel is burnt by cars around the world everyday, if cars disappeared, oil demand will go down drastically.
Lastly, if cars disappeared, car racing championships like Formula One, NASCAR, etc. will exist only on video games.
On the flip side:
Firstly, pollution levels will come down drastically.
Secondly, if cars disappeared, people might start walking or using bicycles to get to work, in turn getting healthier.
Lastly, if cars disappeared, lives will be saved as number of fatal accidents will come down drastically.
What if our Sun became a Black Hole? | #aumsum #kids #science #education #children
Black holes are formed when stars which are about 10 times the mass of our Sun or higher use up all their fuel and explode. Eventually they collapse under the weight of their own gravity and form a black hole.
Now if our Sun became a black hole:
Firstly, it would be less than 6 kilometers across.
Secondly, no guesses here, everything will be pitch dark as there will be no more sunlight.
Thirdly, without sunlight, life as we know it will slowly but surely wither away.
Fourthly, planets in the solar system will not get sucked into the black hole though.
Firstly, Sun will not contain more matter than it has now.
Secondly, Sun's position with respect to the planets will not change.
What If Saturn Lost Control Of Its Rings?
Be like SMART BANANA:
What If Saturn Lost Control Of Its Rings?
Hey, Mr. Banana! Do you remember Saturn? Well, you know, the planet with put-a-ring-on-it attitude. So, rumor has it, the planet is gradually losing control of its huge rings, and if the process continues, flying asteroids, debris and other junk might destroy our Solar system. How?

What if Borders Disappeared? | #aumsum #kids #science #education #children
What if Borders Disappeared?
Firstly, if borders disappeared, there will be no countries anymore, entire world will become one. Every human will deserve a Noble prize if this happens.
Secondly, if borders disappeared, no more visas, no more customs, no more security checks, traveling from one place to another would become extremely easy. Tourism industry would get a huge boost.
Thirdly, huge amount of money is spent on protecting our borders, if borders disappeared, the same could be used for more useful purposes.
Fourthly, if borders disappeared, trade may get a boost, more jobs might be created, world economy might soar high.
Fifthly, if borders disappeared, the huge economic as well as social inequality in the world might come down.
On the flip side, if borders disappeared, some antisocial elements might take advantage of this situation.
What if the Sun Disappeared? | #aumsum #kids #science #education #children
The sun’s enormous mass and gravitational power locks the planets in their orbits. If the sun disappeared, the earth would fly off in a straight line into space. Earth would collapse into darkness only after 8 minutes, as sunlight takes about 8 minutes to reach earth. Moon would disappear as it doesn’t produce light of its own. Plants would die, as no sunlight means no photosynthesis.
Within a week, earth’s temperature would drop below 0 degrees Fahrenheit, dropping to negative 100 degrees Fahrenheit within a year, making it impossible for us to survive. Ocean surfaces would freeze, however, water in the interior would stay liquid, due to heat from the Earth’s core. Only microorganisms who don’t require photosynthesis, would survive by converting core’s heat into the energy they need. Thus, without the sun, humans wouldn’t exist.
What if Coronavirus Disappeared? | #aumsum #kids #science #education #children
Firstly, the current depression filled atmosphere will be replaced with positive smiles all around.
Secondly, people who have been under lockdown for months will surely jump with excitement.
Thirdly, months of lockdown has given people a lot of time to think about life in general. Hopefully after lockdown, we will have a much more cheerful, responsible and fitter society.
Fourthly, schools and industries will open up, people will start going to jobs, the economy will start roaring again.
Fifthly, health infrastructure around the world has been under severe stress, if coronavirus disappears, doctors and nurses will heave a sigh of relief.
Lastly, public health will be given a lot of importance worldwide so that such pandemics do not occur again.
On the flip side, pollution levels might start rising again.

What if we Dig a Hole through Earth and Jump? | #aumsum #kids #science #education #children
Firstly, the atmospheric pressure will crush us.
Because once we go about 40 miles down, atmospheric pressure increases by about 1000 times than that at the sea level.
Secondly, no Fire Suit will be able to help us as the temperature at the core of the earth can reach about 10,800 degrees Fahrenheit.
Thirdly, there is a very high probability that once we reach the other side of the earth, we would fall back again because of gravity, thus we will keep on oscillating like a Yo-Yo.
Lastly, even if we were lucky enough to survive the journey, there is a very good chance that instead of safely landing in a country we would end up in the middle of an ocean.
What if Fishes Disappeared? | #aumsum #kids #science #education #children
Firstly, there are trillions of fishes in oceans, if fishes disappeared, this would be the biggest shock planet earth has received so far.
Secondly, if fishes disappeared, aquariums will contain nothing but water and plants.
Thirdly, millions of people living near coastal areas mostly eat fish, if fishes disappeared, people might start starving due to lack of food.
Fourthly, many people have a hobby of going for fishing on weekends, if fishes disappeared, all of them will come back empty handed.
Fifthly, scuba divers love to dive and explore the wonderful colorful world inside oceans. If fishes disappeared, scuba diving may go out of fashion.
Lastly, fishing industry employs millions of people and is worth billions of dollars. If fishes disappeared, world economy will surely go into recession.
What if we build a Road Around the World? | #aumsum #kids #science #education #children
Firstly, it will definitely find its name in the Guinness Book of World Records.
Secondly, if it had a dedicated bike lane then the entire world will get fitter much faster.
Thirdly, it sounds like a good idea, but would prove to be extremely difficult to execute from geographical, financial as well as political point of view.
Fourthly, global trade will probably get a major boost, it will also prove to be a major engine of worldwide job creation.
Fifthly, car companies would be one happy lot while airplane manufacturers might not be too excited about it.
Lastly, if all the countries were to agree on this, then it would prove to be one of the biggest show of solidarity by humanity.
What if all Animals Disappeared? | #aumsum #kids #science #education #children
Firstly, planet earth is inhabited by billions of mammals and birds, trillions of insects and fishes, it would be impossible to imagine what earth would look like if all animals disappeared.
Secondly, more than 90% of the human population consumes meat, if all animals disappeared, they would have no choice but to turn vegetarian.
Thirdly, livestock industry, meat industry, zoos, national parks employ millions of people, if all animals disappeared, they will have to look for new jobs.
Fourthly, millions of people around the world own a pet, if all animals disappeared, pet owners would need to nurse their broken hearts.
Lastly, animals as well as humans have evolved over billions of years and have become part of a delicate food chain. If all animals disappeared, the entire food chain will collapse.
What if there were no Sharks? | #aumsum #kids #science #education #children
Firstly, the makers of Shark movies will have to search for a new villain.
Secondly, sharks have been around for more than 400 million years, with no sharks, the natural food chain in the oceans might just completely collapse.
Thirdly, with no sharks around to eat those fishes which eat algae-eating fishes, there will be a drastic decrease in algae-eating fishes. This will lead to an exponential increase in the amount of algae. This algae will cover the coral reefs, not allowing it to photosynthesize. This loss of habitat will lead to mass extinction.
Fourthly, sea creatures which depend on shark's nitrogen rich poo for nourishment will suffer.
On the flip side, surfers as well as people with galeophobia i.e. fear of sharks will be one happy lot.
What if Half Earth was Reserved for Wildlife? | #aumsum #kids #science #education #children
Firstly, this will be a historic step by Mankind. Possibly the best step Mankind has taken till now!!
Secondly, with no more humans to boss them around, wild life will be free and extremely happy!!
Thirdly, with so many new trees being added, global warming and climate change might take a back seat.
Fourthly, with such a large area reserved for forests, zoos might become a thing of the past.
Fifthly, people might start going to safaris on weekends instead of going to shopping malls.
Also, domesticated animals like dogs and cats might get jealous of their wild life counterparts.
Lastly, for this to be successful, human beings will have to keep a check on their population as well on their greed.
What if Roads Disappeared? | #aumsum #kids #science #education #children
What if Roads Disappeared?
Firstly, if roads disappeared, rides on even super expensive cars will be extremely bumpy.
Secondly, if roads disappeared, speed limits will come down, people may drive more cautiously as there will be obstacles all around.
Thirdly, especially in cities, huge amount of space is consumed by roads, if roads disappeared, their will be a huge debate on what to do with that space.
Fourthly, if roads disappeared, Google maps may not work anymore.
Fifthly, if roads disappeared, sales of dirt bikes will really pick up.
Sixthly, if roads disappeared, current standards of manufacturing cars as well as tires will have to be completely overhauled as they will not survive this rigid environment.
Lastly, if roads disappeared, even for short distances, people will start traveling by trains, ships as well as airplanes.
What if all the Bees Die? | #aumsum #kids #science #education #children
There are more than 16,000 species of bees. Bees generally collect pollen and nectar from flowers for their survival. In this process, they help pollinate majority of the fruits and vegetable crops which are consumed in the world today. Some studies reveal that more than 90% production of cherries, blueberries and almonds is a direct result of the pollination efforts of bees.
Also, certain bees have evolved as per the size and structure of specific flowers, hence if there are no bees, these plants would definitely go extinct. This will also have a catastrophic effect on the food chain as the animals eating those plants will slowly but surely perish.
Finally, because of the absence of natural sweetener like honey, many people may switch over to an unhealthy artificial sweetener like sugar.
What if Humans were Immortal? | #aumsum #kids #science #education #children
Firstly, planet Earth will be overflown by Humans. As nobody will die, population control will be the single biggest issue worldwide.
Secondly, only immortality is promised but being healthy will be individual persons responsibility. Healthcare will become the biggest industry in the world.
Thirdly, this will be sad news for many animal species. Very few will be able to survive this human onslaught.
Fourthly, many people will be under no hurry to accomplish something in life, creativity might take a huge dip.
Fifthly, many people will probably get bored as they will have no idea what to do after a few hundred years.
Also, with so much time on hand, interstellar travel like the one seen in Star Wars might become a reality.
Lastly, cemeteries and graveyards will be shutdown worldwide.
What if all Volcanoes Erupted at Once? | #aumsum #kids #science #education #children
Even if we ignore underwater volcanoes, there are still about 1500 active volcanoes on earth. There are at least 20 volcanoes erupting on earth at any given moment.
Now, if all the volcanoes were to erupt at once.
Firstly, the entire atmosphere will be covered with clouds of ash and volcanic gases leading to respiratory problems for many.
Secondly, volcanic ash may lead to clogging of plane turbines and eventual engine failure, resulting in the grounding of all the airplanes.
Thirdly, as sunlight will not be able to penetrate the volcanic ash, entire world will be plunged into darkness.
Lastly, Acid rain formed due to the reaction between volcanic gases and various atmospheric gases will destroy crops worldwide and also lead to Ocean Acidification.
What if Universe Stopped Expanding? | #aumsum #kids #science #education #children
Scientists believe that universe will stop expanding when the matter present inside it crosses a critical threshold. If the amount of matter present crosses the critical threshold then the universe will first slow down and then finally stop.
As per scientists as matter has increased so has gravity. So, gravity will start pulling everything inwards. Universe will now start contracting. It will start getting denser as well as hotter as it keeps on contracting further. Eventually it will collapse into singularity. Scientists also refer to this event as The Big Crunch i.e. reverse of The Big Bang.
As per one more research, Dark energy is primarily responsible for the expanding universe. As not much is known about Dark Energy it is difficult to predict its effect on a contracting universe.
Are Frozen foods Safe to eat? | #aumsum #kids #science #education #children
In food industry, there are two processes used for freezing, mechanical and cryogenic. In mechanical freezing, chilled air is passed over food items, causing them to slowly cool down and freeze. While, in cryogenic or flash freezing, food items are either directly sprayed or immersed in refrigerants like liquid nitrogen or carbon dioxide, thus freezing the food instantly.
Frozen foods do have certain advantages. Firstly, nutritional loss is almost negligible. Secondly, while transporting and storing fresh food items, harmful bacteria can grow and contaminate the food. However, this will not happen in case of frozen foods because bacteria don’t usually grow in low, freezing temperatures. However, some frozen foods may contain stabilizers and trans-fat. It is believed that these additives will either increase the risk or worsen certain preexisting health conditions.
What if there were no Schools? | #aumsum #kids #science #whatif #children
Firstly, with no schools, kids will be at home all day, parents will probably have no idea what to do with them.
Secondly, with no schools, movie theaters and theme parks will be crowded all day long.
Thirdly, with no schools, online learning will become extremely popular.
Fourthly, with no schools, parents will start teaching their kids, teachers will have to look for new jobs.
Fifthly, with no schools, kids will probably have no future career plans, career counselors will have a tough task in front of them.
Lastly, with no schools, there will be no grades or report cards, employers will have to recruit people based on their practical skills.
On the flip side, with no schools, outdoor games will become more popular, kids will probably become more physically healthy.

What if a Massive Solar Flare hits Earth? | #aumsum #kids #science #education #children
Solar flares are sudden and massive eruptions of electromagnetic radiation from the sun's surface. A massive solar flare which occurred in 1859 had minimal impact, but it would have massive disruptions today, mainly because of our over reliance on technology. The earth's surface would be safe but our atmosphere would bear the entire brunt of radiation, that is, radio waves, X-rays, gamma rays, etc.
Firstly, there would be a major disruption of power grids, possibly leaving cities or even countries without any electricity. Secondly, our good old radio communication would be down and out. Thirdly and most importantly, GPS & Satellite Communications would be hit, this would cause major problems for transportation & communication. Lastly, because of massive Auroras our atmosphere would look like a magnificent painting.
Gravity - Why are planets spherical? | #aumsum #kids #science #education #children
Why are planets round?
Because I commanded them.
Planets are round because of the force of gravity.
Gravity acts as if it originates from the center of a planet and pulls each point of the planet towards it.
Hence, the only way for everything on the surface to be equally close to its center is to form a round shape.
However, planets are not exactly round. They are roughly spherical. This is because planets spin on their axes.
Just like a spinning top, right?
When planets spin, things near the equator tend to move away from the center due to centrifugal force, resulting in formation of an equatorial bulge.
Because of this bulge, the equator of a planet becomes farther from its center than its poles, creating a roughly spherical planet.
What if there were No Clouds? | #aumsum #kids #science #education #children
Firstly, without any clouds, sunsets would no longer look spectacular.
Secondly, without any clouds, there would be no way to redistribute fresh water from one place to another because no clouds means no rains. Eventually, all the water present on earth would evaporate and our earth would begin to look like mars, dry and barren.
Thirdly, temperatures would suddenly rise during daytime and drop at night. This is because clouds help regulate temperature. As clouds are generally white in color, they reflect a good amount of sunlight, thus helping keep our day temperatures down. But at the same time, at night, they don't allow all the heat reflected from earth to escape, thus not allowing our nights to get too cold.
What if we could Breathe Underwater? | #aumsum #kids #science #education #children
Firstly, we could just jump in and checkout the amazing coral reefs.
Secondly, the way we fish could change forever, no more need of those fishing rods, just jump in and catch your fish.
But on the flip side, we will suffer from hypothermia if we start staying in water for a long time.
Secondly, our eyes have not evolved to see underwater, also many water bodies are not clear enough for us to see far off objects.
Thirdly, communication would be a huge problem, talking under water will not be easy and our present electronic devices will not work efficiently under water.
Lastly, this might be very bad news for many species living under water as people will start building their homes under water.
If The Earth Had Rings Like Saturn..?
What If The Earth Had Rings Like Saturn..?..and how would it look from space and on Earth...?
Is Running Bad for Knees? | #aumsum #kids #science #education #children
Some people believe that running is bad for knees because it causes arthritis. However, a research states the opposite.
Volunteers were made to run for 30 minutes on a treadmill. Post running, certain substances associated with arthritis, were found less in the synovial fluid present in the knee, and more in the blood. Thus, running might have squeezed these substances out of the knees, reducing the risk of arthritis.
But yes, certain factors could cause trouble to the knees. Running on concrete surfaces can damage the cartilage in knee joints. The softer the surface, the more joint-friendly it is. Weight is another factor. Heavier the person, higher the risk of knee injuries. The right shoe choice is also important. And lastly, cartilage loss could happen with age, increasing the risk of knee injury.
How do Hormones work? | #aumsum #kids #science #education #children
In our body, there is an endocrine system which consists of several glands. These glands secrete various hormones and release them usually into the bloodstream. Now, our cells have specialized receptors on them. A hormone will attach only if there is a receptor for that hormone, ensuring that just the target cells get stimulated. When the cells get stimulated, specific processes in the cells increase or decrease, thus helping us regulate our heartbeat, blood pressure, body temperature, sleep, etc., thus maintaining our health.
For example, if blood sugar level drops, pancreas will secrete a hormone called glucagon. Glucagon will attach to receptors of liver cells and instruct them to convert stored glycogen into glucose, thus increasing our blood sugar levels. Thus, hormones are super important for our body.
Why is Equator Hot but Poles are Cold? | #aumsum #kids #science #education #children
Firstly, around the equator, sunrays hit the ground at a 90-degree angle. Hence, more solar energy falls per unit area, thus making equator hot. However, near the poles, since sunrays hit the ground at a lower angle, the rays spread, causing less energy to fall per unit area, thus making poles cooler.
Secondly, due to the earth’s axial tilt, poles don’t receive sunlight for many months during the year, thus worsening the situation.
Thirdly, as sunlight takes a long path to reach the poles, it has to deal with a greater number of atmospheric particles which results in more absorption and scattering of sunlight. Thus, less sunlight reaches the poles.
Lastly, snow at the poles reflects 75 to 95% of sunlight which is much more as compared to that reflected by the land around the equator.
What is Sleep Apnea? | #aumsum #kids #science #education #children
Sleep apnea is a sleep disorder in which breathing is repeatedly interrupted during sleep. There are three types of sleep apnea.
First is obstructive sleep apnea in which the muscles and soft tissues present at the back of our throat relax and collapse, blocking the breathing passage and thus, preventing the inhaled air from reaching the lungs. Second is central sleep apnea in which our brain fails to send appropriate signals to the muscles that control breathing. Now, although the breathing passage is open, the muscles don’t perform their tasks, hence breathing stops. Third is mixed sleep apnea in which a person suffers from obstructive sleep apnea as well as central sleep apnea.
Now, in all the above three types, lack of oxygen and shortness of breath trigger our brain to wake us up from sleep so that we can start breathing again.
Lunar Eclipse - Why does the moon turn red? | #aumsum #kids #science #education #children
Topic: Lunar Eclipse
Why does the moon turn red?
To scare us.
Moon does not have light of its own.
Why? Didn't he pay the electricity bill.
Sunlight or white light is a mixture of visible colors.
Now, when the sunlight falls on the moon, it reflects all these visible colors equally, making the moon to mostly appear white.
However, during a lunar eclipse when the earth is exactly between the sun and the moon, the moon appears red.
This happens because of the earth's atmosphere.
When the sunlight coming from the sun passes through the earth's atmosphere, the earth's atmosphere scatters the colors of the sunlight having shorter wavelengths. However, red color which has the longest wavelength is least scattered.
Hence, it makes its way to the moon, making it look red.
