This is a great summer science activity which introduces new concepts such as weight, density and bouncy and builds second language vocabulary. For this activity I set out a number of objects on trays mark float and sink. We tested a couple of these in a bowl of water during our morning circle. Later we revisited this as a group, trying new objects found in our environment. The activity was then set up for them to try during the day.
On trying new objects, they will make a connection between the objects weight and the outcome of the experiment. They will also learn which materials will float or sink. Finally, they may also notice a rise in water level with denser objects.
