In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

In this activity, learners build a carousel toy that spins when pushed down.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

In this activity, learners explore the relationship between electric charges and magnetic fields.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

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 model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this water activity, learners discover ways to move water across the water table.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg
