In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

In this activity, learners will use bubble wrap to print patterns on paper and experiment with mixing colors.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.
