Forces and motion
Pushes and pulls, simple machines, magnets and building strong structures.
Lessons
Pushes, Pulls and Magnets
Why a rolling ball always stops, whether a magnet can pull through a table, and how far a paper clip will jump. Three lessons on the pushes and pulls that start, stop and steer things.
Forces and Motion: Crash, Push and Stop
Why you lurch forward when the bus brakes, how fast a toy car really goes, why heavier carts hit harder, and how to build a crumple zone that saves an egg. Four lessons on inertia, speed, mass and stopping safely.
Forces at Work: Gravity, Resistance, Levers and Pulleys
Do heavy things really fall faster? Why are fast swimmers shaped like torpedoes? How can a small push lift a big load? Three hands-on lessons on gravity, air and water resistance, friction, levers and pulleys, measured in newtons with homemade and simple tools.
