20 Fascinating and Little Known Science Facts for Kids

 

Have you ever wondered about the mysteries of the world? Is your mind powered by curiosity? Well, we have something that will satisfy that thirst for knowledge.

One of the best things about kids is their exploring and curious nature that makes them question the unquestionable. That's why we have pulled out some fun facts and some not as widespread science facts that can make any child even more excited to explore. Let’s get started!

 

  1. Earth formed about 4.5 billion years ago.

Our planet has a long history – to say the least. It is estimated that planet Earth is 4.543 billion years old (plus or minus about 50 million years). The Sun and the Moon are approximately the same age.

 

  1. It is estimated that there are around 8.7 million species on Earth.

Out of these 8.7 unique species, 2.2 million of them are in the oceans, and the rest of the identified species are on land. However, scientists estimate that 91% of ocean species have yet to be classified.

 

  1. Only 2.5% is freshwater.

Even though almost 70% of the world is covered by water, only 2.5% of it is fresh. Since much of it is trapped in glaciers and snowfields, just 1% of the freshwater is easily accessible. The rest of the water is saline and ocean-based. What this means is that only 0.007% of the planet's water is drinkable.

 

  1. A lightning strike is hotter than the Sun.

A lightning strike can reach the temperature of up to 54,000 degrees Fahrenheit (30,000 degrees Celsius). This makes it about 6 times hotter than the Sun’s surface.

 

  1. 99% of our DNA is the same.

Each of us shares 99% of the DNA with every other human being. You see, we're so much more alike than you might think.

 

  1. If you were to uncoil all the DNA, it would be long enough to make 17 round trips from the Sun to Pluto.

There are around 37 trillion cells in the human body. When uncoiled, the DNA in all the cells in your body would stretch 10 billion miles.

 

  1. People get taller in space.

Do you want to grow real fast? No problem! Just head to space. Since there is no gravity pulling down on them, people get a little taller in space.

 

  1. People’s sneeze can travel up to 100 miles per hour.

The fastest recorded sneeze was 102 miles per hour. Imagine if you could run that fast now that would be a cool superpower!

 

  1. Fleas can jump 130 times higher than their own height.

To put this in a human perspective, if a flea were a six feet tall person, it could jump 780 feet high. That would take jumping jacks to a whole new level.

 

  1. Killer Whales are actually dolphins.

Orcas or Killer Whales aren't whales. They are, in fact, a type of dolphin or, to be more precise, the largest breed of dolphins out there.

 

  1. Hummingbirds are the smallest birds in the world with the fastest wings.

Hummingbirds may be the smallest breed of birds, but their wings are mighty! The ruby-throated hummingbird can beat their wings up to 200 times per second. But that’s not all! Hummingbirds are the only birds that can fly up and down, hover in mid-air, fly backward and sideways.

 

  1. The first electronic computer was the size of a large room.

Electronic computers weren’t always as handy as they are today. “When they were first developed around the 1940s, electronic computers couldn’t even fit in a smaller room,” said Joshua Harrison, a computer programmer and science writer at TrustMyPaper. “Now imagine how far we have gotten when we have miniaturized these computers to be embedded in cell phones, toys, and whatever you wish,” Joshua added.

 

  1. Leonardo da Vinci sketched out the first working design for a humanoid robot.

Yep, that’s the same guy that painted Mona Lisa. But he was more than just an artist. He was an innovator. A man that was far ahead of his time. His passions included astronomy, mathematics, geology, geometry, botany, pyrotechnics, optics, and zoology. Back in the 15th century, Da Vinci created a humanoid robot that could wave its arms, sit down and even open and close its mouth.

 

  1. The oldest Ancient Wonder of the World is the Great Pyramid of Giza.

Out of the Seven Wonders of the World, the oldest one is the Great Pyramid of Giza, also known as the Pyramid of Khufu or the Pyramid of Cheops. It is located in Egypt, and it is estimated that it was constructed around 2560 BC.

 

  1. Rabbits and parrots can see behind themselves without turning their heads.

These two species are the only ones who don’t need to move their head to see what’s happening behind them. That’s because their eyes are positioned on the sides of their head, which allows them to swivel 360 degrees. The expression "you have eyes in the back of your head" can easily be transformed into "you have rabbit's eyes."

 

  1. Elephants can sing like humans.

It seems like we have some singing competition. Researchers have found that elephants use ultrasound rumble to keep their herd together as well as to find mates. Unfortunately, people can’t hear their “singing” because the vocal sound is too low for us to hear.

 

  1. A hippopotamus can outrun a man.

Don’t underestimate the big old hippopotamus. They may seem huge, lazy, and slow, but they are run faster than humans.

 

  1. Butterfly’s taste receptors are in their feet.

Butterflies taste food with their feet. Just like humans taste food with their tongue, butterflies do that by standing on top of the food.

 

  1. Strawberries are the only fruit with their seeds on the outside.

Strawberries proudly wear their seeds for everyone to see! They are the only fruit that does that. The average berry has about 200 seeds. What’s also interesting is that botanists consider each seed on a strawberry to be its own separate fruit.

 

  1. Cucumbers are fruit.

This so-called vegetable is, in fact, a fruit. Cucumbers are a part of the melon family.

 

Final Thoughts

This is just a fraction of the facts that make up the mosaic of our planet. We'll just tickle the imagination and let our little scientists keep exploring and researching the world of science.
