In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

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.
