Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

Learners construct and launch paper helicopters.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.
