In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

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

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this math activity, learners observe and sketch cracking patterns in pavement.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.

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.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

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 (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.
