Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this activity, learners will explore acid-base reactions and create their own bubbly results.

Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

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.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

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

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.
