In this exercise, students will study a number of materials to see whether or not they are conductors.
Genecon and Lost Energy
Genecon and Lost Energy
Students will operate a Genecon Hand Crank Generator to study the Law of Energy Conservation.
Racing Marbles: The Race
Racing Marbles: The Race
Students will simultaneously roll two marbles down separate ramps with contrasting designs and predict which marble will win a race.
Observing Acceleration with an Accelerometer
Observing Acceleration with an Accelerometer
Students will use a liquid accelerometer to observe different types of motion and classify the acceleration. 
Lab #35.3   Electric Circuits: Be The Battery
Lab #35.3 Electric Circuits: Be The Battery
