Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
How Far?
To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.
Perching Parrot
Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.
Hovercraft Racers!
Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).
Action-Reaction Rocket!
Learners construct a rocket from a balloon propelled along a guide string.
Blow-and-Go Parachute
Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.
Hanging Around
Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.
Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.
Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
How Do Things Fall?
Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.
Skateboard Disaster
Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.
Breaking Beams
Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
Fun with Bernoulli
Learners conduct four simple experiments to demonstrate the effects of air pressure.
Floating and Falling Flows
Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.
I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.
