In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this activity, learners explore sublimation by conducting experiments with dry ice.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

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 learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.
