Curated OER
Forces Acting on a Spring
Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is...

Hooke's Law, Vibrations, Mechanical Waves, and Sound
Dangle a spring to experiment with vibration and discover if period is dependent on amplitude. Strum a guitar and adjust the strings to compare displacement and sound. Use a Slinky® and guitar strings on a ring stand to uncover the...

Breaking the Mold
A little too much strain could cause a lot of stress. Groups conduct a strength test on clay. Using books as weights, pupils measure the compression of clay columns and calculate the associated strain and stress. Teams record their data...

Projectiles: Target Practice
Angry Birds prepared them, but now pupils must prove their skills with projectiles! Scholars test different variables to determine which ones impact the distance the projectile flies. The experiment provides connections to kinetic and...

Model of a Black Hole
Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.
Illustrative Mathematics
Bank Shot
Young geometers become pool sharks in this analysis of the angles and lengths of a trick shot. By using angles of incidence and reflection to develop similar triangles, learners plan the exact placement of balls to make the shot....

An Egg-Citing Ride
Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.

Conservation of Momentum: Marble Collisions
What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...
