Thrown for a Loop
Round and round it goes. Class members observe a current carrying loop in a magnetic field and calculate its associated torque. They then apply what they have learned to example problems to solve for the torque and to calculate the...
Curated OER
Laser Types and Uses
Students examine the properties of lasers and research their types and uses. In this laser lesson students view several demonstrations.
Curated OER
Learning Light's Properties
Students examine the properties of light and the behavior of light during interference. In this electromagnetics instructional activity students explain behaviors of light.
Curated OER
No Valve in Vain
Students design and create their own heart valves out of a variety of materials. Their heart valves are one way valves designed for water flowing through a tube representing blood moving through the heart.
Curated OER
Viral Hijackers
Students discover how viruses effect living organisms. Focusing on HIV, they explain why it is unique and how it attacks the immune system. They simulate the spread of viruses through an experiment using water containing sodium...
Curated OER
Tracking a Virus
Students simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be tainted with...
