In this activity, learners explore how polarizing sunglasses can help diminish road glare. By rotating a pair of polarizing sunglass lenses or other polarizing materials, learners will discover that some angles are better at reducing glare than others. Learners observe light from the sky, reflected from a mirror, or reflected from the surface of a pond. Use this activity to introduce learners to principles of light and polarization.

In this video segment from Cyberchase, the CyberSquad breaks down an action into a series of steps in order to program a robot to do what they need it to do.

In this unit of study students learn that in the horizontal direction a projectile moves at a constant speed with nothing to cause acceleration. In the vertical direction a projectile accelerates due to the earth’s gravitational field. And combining these two type of motions together you can determine the parabolic arch of a projectile. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.

Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target.

Science Phenomena: HS Physical Science - Forces and Interactions - Asteroids have the potential to cause catastrophic loss of life on our planet upon impact. In 2013, the Chelyabinsk meteor injured 1500 people when it exploded over Russia. If researchers could identify potential asteroids early enough they could change their orbit to eliminate the threat to Earth. This phenomenon could be used to explore the motion of orbiting objects in the solar system or to gain a better understanding of gravitational forces and fields.

Students will investigate the interactions between colliding objects using pushes and pulls. After listening to the book, Push and Pull by Charlotte Guillian, students will play a game of kickball and observe how the ball is pushed, pulled, started, stopped, collided with other objects and how it changed position and speed. As a group, students will then brainstorm about other objects being pushed, pulled or colliding and choose one of those objects to investigate. This lesson is part of a bigger unit based on this Performance Expectation and items not addressed in this lesson are addressed in other lessons.

The topic of this video is energy in general, and specifically the ways we can quantify it. In order to make the concepts accessible to a broad audience, this video focuses on everyday things and events. How is it that energy plays a part in a child riding a scooter? How is the energy we consume in playing related to the energy on the food we eat? This video poses these questions to the class and challenges them to put a list of five such items into an ordering from most energy to least.

Explore the properties of quantum "particles" bound in potential wells. See how the wave functions and probability densities that describe them evolve (or don't evolve) over time.

When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.

The electric field lines from a point charge evolve in time as the charge moves. Watch radiation propagate outward at the speed of light as you wiggle the charge. Stop a moving charge to see bremsstrahlung (braking) radiation. Explore the radiation patterns as the charge moves with sinusoidal, circular, or linear motion. You can move the charge any way you like, as long as you don’t exceed the speed of light.
