Newton's Apple
Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

Third Law Simulation
Keep calm and use the force! Joey pulls a cart and scholars adjust the force required to control the movement. Through simulating different scenarios, participants learn about Newton's Third Law. It includes analysis questions throughout...
Concord Consortium
Pendulum
Add some zing to your swing! Explore pendulum motion through an engaging interactive. Physical science scholars specify the pendulum's mass, rod length, and starting angle before they observe the resulting angle graph.

Orbital Motion
Why do planets orbit the sun in ellipses when moons orbit their planet in circles? Pupils control the semi-major axis, eccentricity of the orbit, and position angle. The resulting orbital appears with the related force vectors as...

Concentrating Charge and Electric Fields
How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...
Curated OER
Model Rockets
Students build a model rocket. In this model rocket lesson, students explore a rocket launch cycle. Students investigate the laws of physics for each part of the launch. Students build model rockets and launch at school.
Curated OER
Push and Pull Factors: Tug O' War
Students analyze the factors that led to migration in the 19th century including the forces that drew people to resettle as well as to return a place where they previously lived.

Sars
Students discuss the Sars outbreak in 2003. In this biology lesson plan, students research the effect of the outbreak to the world. They create a public announcement about the topic.
