1. 1

    Hold a ball out and let go. Ask: 'Why did it fall down and not up?' Say: 'The earth pulls everything toward it. That pull is called gravity.'

  2. 2

    Take the two balls. Let the child hold both and say which is heavier.

  3. 3

    Ask which will land first. Hold both at the same height over the mat and let go at once.

  4. 4

    Listen: 'One thump. They landed together.'

  5. 5

    Repeat with the two blocks.

  6. 6

    Drop the flat paper and the crumpled paper together. Watch the flat sheet float down slowly: 'The air pushes up on the flat paper and slows it.'

  7. 7

    Invite the child to drop each pair and place a prediction card first.

What catches the child’s eye

  • One single thump when two very different balls land at the same moment
  • A flat sheet of paper drifting side to side while the crumpled one drops straight down

Extensions, easiest to hardest

  1. Drop a flat sheet and a crumpled sheet, then fold the flat one and compare again
  2. Drop a feather and a coin and talk about why the feather is slower
  3. Find things that fall in daily life: leaves, rain, snow
  4. Record each pair's result on a simple chart

Control of error

The sound shows the result: one thump means they landed together, two thumps means one was first.

Ready to move on when the child…

  • Lets go of both objects at the same moment from the same height
  • Says that gravity pulls things down
  • Predicts and checks with each pair

Guide note

Drop objects from standing height only. Children do not stand on chairs or tables to drop things.

Try “pink tower”, “tummy”, “diaper”, “grace and courtesy”, or “October”.
