In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

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

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

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 activity, learners explore a surprising method for calculating the mathematical constant pi, known as Buffon's Needle.

En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.

In this activity, learners will construct an air cannon as a model for the human ear.

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.

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 weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.

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

In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

In this engineering design challenge, learners build an air-powered spinning machine.

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

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

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