In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

In this activity, learners design a bungee jump for an egg using nylon stockings.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

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 activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.
