Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this experiment, learners float colored ice cubes in hot and cold water.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.
