Introduction

Science is cool. Science has given us the ability to travel through space and time, it's taught us how to cure diseases, and it's changed our lives for the better. It's also something that you should be proud of knowing about! Here are 10 fun facts about science that you may not know yet:

1. The sun is made up of a burning ball of gas called plasma.

The sun is made up of plasma, which is a state of matter. The sun contains hot gas that can be ionized and become a plasma. Plasma is not visible to the naked eye in its solid form, but it still exists as a gas and therefore has properties similar to those of other states of matter like liquid or solid.

Plasma has been known since ancient times as “the fourth state” because it was believed to have existed before any other kind of material in nature—and indeed it does! Plasmas behave differently from all other materials found on Earth: they conduct electricity better than any other substance does, for example (this makes them useful for creating electric devices).

2. It's impossible to sneeze with your eyes open.

You may know that it's impossible to sneeze with your eyes open, but did you know that it's also possible to sneeze with your eyes closed? The answer is yes.

The reason why we can't sneeze with our eyes open is because of how the nostrils work. When you're breathing in through your nose and out through your mouth, there are small hairs called cilia on either side of each nostril that move air into them so they can expel it at the same time as inhaling new air from outside. If these cilia were longer than normal (like a person who has very short hair), then they wouldn't be able to do their job properly—which would cause us not only not be able to breathe properly but also unable to smell anything good or bad! So when we're trying not fall asleep during class lectures or movies where everything happens right away without any breaks like commercials etc., keep an eye on those poor kids who keep falling asleep despite being given instructions about how much longer before next break should occur."

3. The human body has enough fat to produce seven bars of soap.

  • Fat is an excellent insulator. It can keep you warm in winter and cool in summer, so it's a good source of body heat. Fat also provides energy for your brain and muscles, which are critical to survival.

  • A single gram of fat contains nine calories—more than twice as many calories as protein or carbohydrates (sixteen to eleven). The body can effectively break down fats into ketones when they're needed by the brain, but this process releases free fatty acids into your blood stream that have been stored there waiting to be oxidized. This process produces more oxygen than glucose does during exercise because it relies on oxygen-carrying molecules called haemoglobin instead of sugar molecules like glucose.*

4. There are about one trillion bacteria on each of your feet.

While you may not be able to see them, there are about one trillion bacteria on each of your feet.

Bacteria help to break down food, so they're important for the digestion of food. They also help to keep the gut healthy by breaking down waste and producing vitamins. Bacteria is also used by skin cells as part of an immune system reaction when we get sick or injured; when this happens, it can cause redness and swelling around an injury where bacteria are present (for example: stings from bees). Finally, many species within this group produce compounds called "secondary metabolites" which may have health benefits such as fighting cancerous cells or preventing mental disorders like depression—these substances act as natural medicines!

5. It takes less than eight minutes for the sun's light to reach Earth.

The sun is a star, and it is 93 million miles away. It's huge! But not the biggest star in our galaxy or even our universe. That honor goes to Betelgeuse, a red supergiant star located about 360 light-years away in Orion's shoulder (or "shoulder" if you're an astronomer). The next closest thing to Betelgeuse would be Rho Ophiuchi A—a variable red supergiant located about 490 light-years from Earth—and then there are many more stars than either of them: over 400 billion according to NASA estimates!

In fact, most stars aren't spheres at all but instead have irregular shapes due to their rotation around their axes; they're actually oblate spheroids when viewed from above (as opposed to being prolate spheroids like our own moon).

6. You produce about one litre of saliva a day, which is enough to fill two swimming pools in a lifetime!

Saliva is a sticky, gooey substance that helps to break down food and keep your mouth moist. It contains water, mucus and enzymes. The amount of saliva you produce varies from person to person depending on their diet and other factors.

You can produce about one litre of saliva a day, which is enough to fill two swimming pools in a lifetime!

7. You lose 30,000 dead skin cells every minute - that's equivalent to losing 20kg in a year!

Skin is made up of three layers - the outermost layer, called the epidermis; an inner layer called the dermis; and another inner layer called the subcutaneous fat.

You lose 30,000 dead skin cells every minute – that's equivalent to losing 20kg in a year!

To put this into perspective: if you were to take all your dead skin cells and weigh them all together they would weigh more than 5kgs!

8. A single human brain generates more electrical impulses in a single day than all the telephones in the world combined!

A human brain generates more electrical impulses in a single day than all the telephones in the world combined!

The brain is a complex organ that is the most complex organ in your body. It also happens to be one of the most active organs, generating electrical impulses at an incredible rate. The brain is responsible for everything you do, think and feel—making it an important part of being alive.

9. Lightning bolts can be up to 5 miles (8km) long and 50,000 °F (28,000 °C).

Lightning is a powerful electrical discharge that occurs during thunderstorms. A bolt of lightning can be up to 5 miles (8km) long, and up to 50,000 °F (28,000 °C).

Lightning is a flash in the sky caused by an electrical discharge between clouds and Earth's surface. The resulting current travels along the ground until it reaches the earth's surface through a cloud or wall of water droplets called raindrops. When it hits the ground or water at great speed (upwards of 100 miles per second), this lightning bolt causes an explosion that creates heat similar to that of an atomic bomb exploding within inches from your face! You may have seen this phenomenon when watching TV shows on science channels where they show footage from space showing all kinds of things happening in space including hurricanes blowing around planets like our own earth but here we talk about what happens right here on Earth!

10. There are more stars in space than there are grains of sand on every beach in the world!

You’ll be shocked to learn that there are more stars in space than there are grains of sand on every beach in the world. That’s right—the number is over 6 billion!

The reason why this seems so unbelievable is because it doesn't seem like something you could fit all those tiny objects together, but they can actually be stacked and packed tightly enough together to create a mountain range-sized pile (that's about 400 million cubic kilometers). The same thing goes for sand on beaches—if you were able to have an entire beach full of them, they would still not even fill up one percent of our solar system!

Science is cool. It’s also important, and it’s even more fun than you think! In fact, science can be so much more than simply a hobby or a passion—it can be an adventure.

Now that you know why science is so awesome (and how it helps us understand the world around us), let's dive into some facts about science itself.

Conclusion

So there you have it, ten fun facts about science! We hope you enjoyed these as much as we did writing them for you. Thanks for reading our blog and we’ll see you next time!
