Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Learners follow the template to build and fly a paper helicopter.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

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

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

In this activity, learners construct paper airplanes that twist and turn.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
