How to Teach Kids about Space: 10 Key Concepts for Young Explorers [Space Themed Activities Series]

Welcome to our Space Themed Activities Series, where we delve into the fascinating world of space education for kids. By introducing these foundational ideas, we aim to provide parents, educators, and caregivers with a simple guide to engaging and educational space-themed activities that will leave a lasting impression on young minds.

When it comes to space, you may feel perplexed with the overload of complex information available. You may wonder what is appropriate for a preschool child to know. In this article, we will explore "How to Teach Kids about Space" by focusing on 10 key concepts that will ignite their curiosity and inspire their inner young explorers. Remember this is not a complete list, if your child is a space enthusiast, you can tell them about more ideas like "sunspots" and "supernovas". But on a basic level, described below are the 10 concepts that over the preschool and early primary years, you can aim to explain to your child.

👉 Remember, colourful books and engaging play or activity ideas are best to teach children, instead of hard facts told without context.

10 Things to Teach Kids about Space

1. Space is vast and infinite:

Space is incredibly big, and it goes on forever. It's much, much bigger than anything on Earth! Imagine all the places you know on Earth, like your house, your school, and your favorite park. Well, space is even bigger than that! It's so big that it's impossible to explore it all. Scientists believe that there are billions and billions of stars, planets, and galaxies out there waiting to be discovered.

2. Planets and Stars:

In space, there are planets like our Earth, and also stars like our Sun. Our solar system, where we live, has 8 planets. Each planet is different and unique in its own way. Some are big, like Jupiter, while others are smaller, like Mercury. Stars, on the other hand, are huge balls of hot, glowing gas that give off light and heat. They can be much bigger and brighter than any planet.

[Optional: Many, many stars together form galaxies. And there are many many galaxies in the universe.]

3. The Moon:

The moon is not a star or a planet, but it is a big ball of land that orbits around our Earth. We sometimes see it at night, and its shape seems to change because of the way the Sun's light hits it. The moon is Earth's closest neighbor in space. It doesn't have any air or water like Earth, but astronauts have visited the moon and left footprints there!

4. Astronauts:

People who go to space are called astronauts. They wear special suits and helmets and travel in spaceships. Astronauts have a very important job. They conduct experiments, explore new places, and learn about space. They need to train very hard to be able to go into space because it can be a dangerous and challenging place.

[Optional: Tell them about famous astronauts, about International Space Station, and about current space expeditions of various countries]

5. Gravity:

Gravity is a force that keeps us on the ground. It's what makes objects fall when we drop them and keeps our feet on the Earth's surface. But did you know that gravity is different on other planets and even the moon? For example, on the moon, gravity is much weaker, so astronauts can jump and bounce around!

6. No Air in Space:

Space is a vacuum, which means it doesn't have air or oxygen. That's why astronauts wear helmets with oxygen in them. In space, there is no air to breathe, no wind to feel, and no sound to hear. It's a completely different environment from what we are used to on Earth.

7. The Sun is a Star:

The Sun, which gives us light during the day, is actually a star. It's like a big ball of hot, glowing gas that gives us light and warmth. It's much closer to Earth than other stars, which is why it looks so big and bright. The Sun is so important because it provides us with heat and energy. Without the Sun, life on Earth wouldn't be possible! It is because of the Sun that we have day and night and different seasons on Earth.

8. Black Holes:

Imagine a black hole as a very, very, very, strong and powerful vacuum cleaner in space. It's like a big, invisible monster that sucks in everything around it, even light! Yes, that's right, a black hole is so strong that even light cannot escape from it. It's like a giant hole in space that pulls everything inside. They form when a massive star collapses under its own gravity. It's so powerful that if you were to get too close to a black hole, it would pull you in too!

But don't worry, black holes are very far away, and we're safe here on Earth. Scientists study black holes using special telescopes and tools because they're very mysterious and fascinating. They help us learn more about the universe and how it works. While we can't see black holes with our eyes, we can imagine them as these super powerful space vacuums that are like nothing else we've ever seen.

9. No Sound in Space:

Did you know that in space, there is no sound? It's very different from what we're used to here on Earth. You see, sound needs something to travel through, just like when we speak or hear things around us, the sound travels through air. But in space, there is no air or atmosphere like we have here.Because there is no air in space, sound can't travel like it does on Earth. So, in space, no one can hear you scream! Imagine floating in space and trying to talk to someone. They wouldn't be able to hear you because sound waves need air or other materials to travel through.

So, when astronauts are floating in space, they can't hear each other or any sounds like we do here on Earth. They use special radios inside their helmets to talk to each other and communicate with mission control on Earth. These radios work differently and send messages using radio waves that can travel through space without needing air.

But that doesn't mean space is silent! There are still lots of things happening in space, like stars exploding or planets moving. We just can't hear them because there's no air to carry the sound waves to our ears.

10. Telescopes:

We can use tools called telescopes to look at space from Earth. They help us see planets, stars, and even galaxies very far away. Telescopes have lenses and mirrors that gather and focus light, allowing us to see things that are too far or too faint to see with our naked eyes. They help scientists discover new things about the universe and expand our knowledge of space.

Space is a fascinating and endless adventure, and there is so much more to learn and explore. Let your child's imagination soar as we discover together the wonders of the cosmos during our Space Week!
