the kids collected things from around the house and backyard.
There only instructions were to pick something and say if they think it will sink or float. I logged their perdictions and then we took everything to the water table to see if their perdictions were correct.
They tested all the items and were mostly right
they used their magnifying glasses both while observing the items to see if they sank or float and also while choosing their items and making their hypothesis.
This was a lot of fun the kids enjoyed it and want to do it again. It was interesting to see their reactions when things did not go as planed (i.e. they predicted this would float but it did not) they both would inspect the item and try and decide why it did not do as they had thought.
