Friction and gravity are always at odds! Learners complete a set of activities to explore the relationship between friction and gravity. Groups make conclusions about the factors that affect the amount and type of friction between surfaces.

Twisting and turning through the sky, roller coasters are popular attractions at amusement parks around the world, but how exactly do they work? Explore the physics behind these thrilling rides with an engineering design activity....

Slip sliding away. Groups investigates the two types of friction by running an experiment that allows them to calculate the coefficient of static friction and the coefficient of kinetic friction. The experiment uses a box, a...

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

Skate through a simulation on energy with an a activity that uses a computer simulation of a skater to reinforce the concept of conservation of energy. The resource guides pupils through scenarios using the computer simulation to...

Rolling for momentum. As part of a study of mechanical energy, momentum, and friction, class members experiment rolling a ball down an incline and having it collide with a cup. Groups take multiple measurements and perform...

Discover the science of NASCAR! Young scholars rev up their learning as they explore aerodynamic principles. Hands-on activities help learners understand concepts of friction, kinetic energy, and potential energy.
