The Doppler Effect
In 1842, Christian Doppler proposed a theory relating the change of wavelengths based on motion. Young scholars observe the Doppler Effect on a small scale in a ball, on a larger scale from a car, and on the largest scale studying the...

Special Relativity
According to Einstein's Theory of Special Relativity, time moves slower when you're working. That's not quite what it says, and in a hands-on lesson, pupils learn the actual theory. Scholars plot the half life of muons, then compare it...

Speedy Light
We know the speed of light, but can we measure the speed of dark? During the lesson, scholars perform gedanken, or thought experiments related to the speed of sound and the speed of light.

A Moving Frame of Reference
We often remind pupils to cite their references, but this lesson helps them understand there are many frames of reference. Scholars experiment with throwing a ball straight up in the air and catching it. Then they must do it again while...

Inferences of Waves
Building on the previous lesson, scholars use Slinkies to create standing waves. They graph waves on a calculator and then apply their knowledge to both sound and light waves. This is the fourth in a series of nine lessons.

Slinkies and Waves
Slinkies® are a great tool for visualizing waves. Pupils work in groups to create both transverse and longitudinal waves before using a polarizer to analyze the ways they are able to travel.

Newton's Law of Universal Gravitation
While science is looking for correct explanations, pseudoscience often fills in the blanks. Pupils explore the relationship between light distance and intensity and graph their data. Then they compare their data to Newton's Law of...

Life (and Death) Before Seat Belts
Did you know only 80-90% of passengers wear a seat belt in a moving car? Young scholars use clay and a cart to complete an experiment about what happens without a seat belt in a collision. The lesson includes Newton's Second Law of...
