Does it sink? Does it float?
This is a fun one you can try in the garden, in the kitchen (if you're brave!) in the bath!
Here are some ideas for investigating sinking and floating
- Beach ball or inflated balloon
- Flowers or leaves
- Empty plastic bottles
- Full plastic bottles
- A sock (it'll float but then sink as it absorbs the water. Unless it really smells then it might just float away)
- The soap! it'll probably sink and you should definitely get an award if you can pick it up first time!
- Anything and everything that you don't mind getting wet!
