Curated OER
Electrical Energy
Students conduct an experiment to find out how well different wires radiate heat when voltage is applied across the wire. They use the results of their experiments to consider how the gauge of the wire and the type of wire affect the...

Coefficient of Kinetic Friction and Surface Area
Young scholars investigate coefficient of friction with respect to surface area and applied force in contact with the sliding force.
