At Fun Science we love doing science at home! Make your very own gravity track, using every day items. This is great fun for a rainy day and can be redesigned countless times! Explore gravity and do a bit of problem solving at the same time!
You will need:
- Toilet and kitchen roll tubes
- A marble (or similar)
- Cut small openings at the end of the tubes so the ball can fit through when it drops.
- Stick the tubes to the wall with the sellotape so that it makes a path for the ball to follow.
- Test your track with the marble, does it work or does it need adjusting?
- Can you make your track last for 10 seconds?
- Try it with different sized/weight balls, what happens?
The science bit:
The ball is carried down the track because of gravity. Gravity is an invisible force that pulls towards the centre of the earth – it’s why we stay on the ground and don’t float away! Gravity is pulling the ball downwards so it travels down the track.
