In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

In this activity, learners explore how boats are engineered to achieve speed.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In two separate bags, learners mix water with Epsom salts and detergent.

This is an activity about friction as well as kinetic and potential energy.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners investigate passive solar building design with a focus solely on heating.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.
