This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners learn about friction by making their own miniature hovercraft.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners discover how solar energy can be used to heat water.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

In this activity, learners make a photographic image—without a camera!

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake

Learners construct and launch paper helicopters.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
