Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

In this activity, learners make their own "tornado" using two soda bottles and water.
