Cable Cars PowerPoint

Cable Cars Physics.ppt

Students build cable cars to apply their knowledge of DC circuits. The tracks are simple bare copper wires attached to either side of the classroom, powered by a cheap DC power supply (I've also used old computer power supplies). Examples of student cable cars are shown in the powerpoint.

Materials: toy propellors, toy motors, hookup wire, bare copper wire for the tracks, DC power supply

Circuit Lab Directions

circuit lab.doc

Students use Ohm's law to predict current's and voltages in three simple DC circuits. Then they build the circuits, test their predictions, and compare theory with reality.

Materials: resistors, batteries, wire, multimeters
