In this activity, learners make an electroscope out of a foam cup, straw, aluminum pie pan, thread, and foil. Learners use their electroscopes to test for static electricity.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

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 on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

This quiz lets you estimate your annual radiation exposure.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
