# The force of gravity

### What to do with this activity?

Ever wondered what gravity is? It's the force that makes sure we stay on the ground rather than float off into space. If you drop something heavy on your toe you know all about gravity!

The famous scientist Isaac Newton (who lived from 1642 to 1727) is said to have developed his theory of gravity because an apple fell on his head.

Watch this video from The Phoenix Learning Group - it explains that gravity is a force pulling everything on earth towards its centre.

Here are some more useful facts about gravity from Ducksters and from Idaho Public Television.

And enjoy a comic animation about the moment the apple fell on Isaac Newton's head and he had his "best idea ever" (although I don't think he made himself apple pie!).

• #### Why am I doing this?

Everyday activities, like shopping and taking journeys provide a great opportunity for your child to practise maths skills by recognising patterns, counting out amounts, working out the best value, weighing and understanding money or understanding timetables and estimating your time of arrival!

• #### How can I do more?

Estimating is a very useful maths skill for everyday life – helping you decide if you have enough money to pay for a number of items or enough paint to paint a room. Encourage your child to estimate, for example, how many potatoes you will need for dinner or how much money to buy the shopping.
