Intensity of Light

Students measure the intensity of a light source vs distance. Using their data they explore the mathematical relationship between intensity and...

High School / Physics

Ohm's Law

Students measure the current and voltage across a resistor while varying the output voltage. A graph of voltage vs current will reveal Ohm's...

High School / Chemistry

Varying Reaction Rates

Students will use a wireless temperature link with a fast response temperature probe to investigate how different temperatures affect the rate...

High School / Physics

Change in Kinetic Energy

Students measure the force from the Smart Fan, then investigate the relationship between the change in kinetic energy and the distance traveled....
