This one is more of a scientific activity than a craft. It will be fun to see who guesses right and who guesses wrong. You'll be surprised of some outcomes! (We got some wrong haha)
Get objects and write down a list of whether it will sink or float on a paper
Get a clear bowl or a clear container (so it's easier to see) and test out your predictions!
How many did you get right and how many did you get wrong? Write it on your list!
