Activity overview

15 mins
Ages 9 – 11

Science topics:

Space

Get your class thinking and talking with this fun question! Having a broad question means you'll get a wide range of ideas coming from your pupils.

Run the activity

1. In pairs, discuss what might be a Plus, Minus and Interesting way to think about the question. Stuck for ideas? They could think about:

  • Where would the Moon go?
  • What would happen to animals that relied on the Moon for navigation?
  • How would it change night time?

2. Ask the children to share their partner's ideas then encourage a broader discussion as a class, remember there is no wrong or right answer!

Background science

The Moon's size (compared to other moons in the solar system) means its presence has a steadying effect on Earth's rotational angle or tilt, keeping it inclined at around 22 degrees.

With no Moon, the Earth would 'wobble', resulting in more dramatic seasons and weather. The Moon is also responsible for the tides, as well as being used by many animals as a navigation aid.

 

Take it further

The National Schools Observatory has a range of excellent free resoruces to help pupils explore more about the Moon. You can also link to their observatory to access the latest images and find out how much pupils would weigh on different planets.

Depending on the time of year, you can sometimes see the Moon in the daytime too. Finally, there's also Moon and Earth lesson plans on this BBC Stargazing Live PDF
