Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge. They will observe how the bridges work under load and discover why engineers...

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds. Learners...

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

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device. This activity can be used as a lesson on...

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move? In this activity, learners explore this classic physics...

In this collection of demonstrations, learners explore Newton's Laws of Motion. These seventeen quick activities investigate air resistance, acceleration, terminal velocity, inertia, action...

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

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. This is an...
