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.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

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

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

Learners build simple catapults and use them to launch cotton balls.

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 examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

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.

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.

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 explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Learners construct and launch paper helicopters.

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.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
