Moon is a satellite

It does not have its own light.

We can see it because it reflects light from the Sun.

Moon is 384 thousand kilometers from the Earth (384.000)

​Moon is captured by Earth's gravity. Gravity does not let Moon fly away and makes it rotate around Earth

The Earth is captured by the Sun's gravity. Gravity does not let the Earth fly away.

​What is Gravity?

​Gravity/gravitational pull

​

• ​All big objects have gravitational pull!

• Earth has it too!​ Gravity acts like a big, powerful magnet in the Earth.

• Gravity pulls strongly on everything on Earth.

• Without gravity, we can't walk on Earth.

The Earth caught The Moon by gravity! That's why the moon won't fly away!

Multiple Choice

Does the Sun have gravity?

Yes!

The Sun magnets all planets ​by gravitational pull!

How does Moon affect Earth?

​Moon has its gravitational pull. It pulls seas' tides. Sometimes tides are low and sometimes they are high.

Multiple Choice

Tides are caused by ___________

• wind

• gravitational pull of moon

• rain

Multiple Choice

Which one falls faster?

​The ball falls faster! Because the bigger object has more gravity!

​The paper falls slower! Because the smaller object has less gravity!

​Can you think of anything that gravity doesn’t affect?

​There is no gravity in space!

​

How can​ astronauts work there?

​Astronauts train under water because it feels very similar to zero gravity.

​

Astronauts must wear special suits in space to keep them warm and help them to breathe because there is no air to breath in space.​

Multiple Choice

Any object with mass experiences gravity

Multiple Choice

Why do astronauts jump so high on the moon?

• The moon has more gravity

• The moon has no gravity

• The moon has less gravity

Multiple Choice

Earth's gravity pulls everything toward:
