In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

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

In this activity, learners create a hearing based memory game that they can share with friends.

In this activity, you'll use a straw, a water bottle and a paper tube to make an instrument that's very much like a saxophone.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.

In this activity, learners will make a thaumatrope, an old-fashioned optical illusion that dates back to the 1820s.

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this math activity (Page 10 of the Play Ball! PDF), learners play a game of "football" and analyze the results of the game.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through.

In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

With little more than a plastic bottle, some vinyl tubing, and a length of PVC pipe, make a rocket and a rocket launcher and investigate how rockets fly.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

This activity explores the concept of center of gravity by having learners build a Jitterbug--a motorized toy that seems to dance--using a recycled CD and a DC motor.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.
