In "Chemistry is Colorful" learners explore different materials through paper chromatography.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

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.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.
