Float or Sink?


Today we are going to look at objects and predict whether they will float or sink when they are put into a bowl of water.


Look at the powerpoint and make your predictions (best guesses).  

Now get a bowl of water and find the objects on the sheet. Please don't worry if you don't have everything, you can use any object that you can find! 



Have another look at the powerpoint. Can you explain why some objects float and some objects sink?

Hint: It's to do with air.
