Stars, Planets and Moons – Earth’s Orbit Activity

This week, my 6-year-old has been enthusiastically learning about the solar system and the Earth’s orbit around the sun. However, she has been struggling to understand the difference between stars, planets, and moons. To help her understand, we tried a fun demonstration in the garden.

Sun, Moon and Earth Orbit Demonstration

First, I made simple hats; one was a Sun, one Earth and the other the Moon. The children each wore a different hat. The ‘Sun’ stood in the middle, while the ‘Earth’ walked around it in a circle. The little ‘Moon’ ran around the ‘Earth’ as it circled the ‘Sun’. Everyone thought this was hilarious, and I think it got the message across, although our Moon was a little mischievous and kept moving out of orbit.

We’ve also used this activity to learn about Copernicus.

Earth’s Orbit

Earth’s orbit around the sun takes 365.242 days (one year on Earth ) and is an elliptical ( slightly oval ) shape. As the Earth rotates around the sun, its tilt changes, which is why we have seasons. When the hemisphere you live in is tilted towards the sun, it’s summer. You can read more about this in my article about the summer solstice.

What is an orbit?

An orbit is a repeating path one object in space takes around another object in space. The object in orbit is called a satellite.
