- Story: pictures from the picture book: Journey to the Moon (see attachment)
- Stones preferably with an irregular shape, both large and small, both light and heavy.
Ideally:
- Large and heavy
- Large and light (e.g. lava stone, but could also be replaced by a sponge)
- Small and heavy
- Small and light
- White sand
- A container (that can hold at least 5 cm of sand)
- (alternatives: sandbox in the playground, flour instead of sand; flour creates more dust/sticks more, sand is “cleaner”)
- A small squeegee (to smooth the sand evenly each time)
- A folding ruler (so the children can easily see from what height their object falls)
- A globe
- A moon (about 1/4 the size of the globe, e.g. a tennis ball painted black).
