Experiment - Float or Sink

I brought in a transparent plastic square container together with some items such as a ping pong ball, a badge and paper clip. None of the children brought anything from home, therefore, they might have to pick something from the classroom for the experiment today.

I poured in some water into the plastic square container and placed it on a table. All the children just observed at first to understand the concept of float or sink. Then it's their turn to try out with other items they could find.

Every time, when a child picked an item, they needed to predict if it will float or sink. After a few rounds, the children somehow understand and could make quite accurate prediction about a particular items from their observation.

Basically, the children picked items such as toy truck, a wooden block, a wooden train track, a plastic block, a plastic bowl, a water bottle, toys etc.
