This lesson is used to review what students may have already learned about circuitry, electricity, and electromagnets. This will offer them the opportunity of 3 very distinct hands-on activities to see these topics in action.
(Most appropriate for grade levels 5-8.)
Lesson Time: 60-70 minutes
Student Activity 1: Students will experiment with solenoids.
Student Activity 2: Students will experiment with St. Louis motor.
Student Activity 3: Students will experiment with hand crank generators.
Group work: Students will work in groups of 3 or 4. In order to save time, teachers are asked to create the groups before our Wizard arrives.
7.PS.3: Energy can be transformed or transferred but is never lost.
7.PS.4: Energy can be transferred through a variety of ways.
8.PS.1: Objects can experience a force due to an external field such as magnetic, electrostatic or gravitational fields.
8.PS.2: Forces can act to change the motion of objects.
PS.EW.5: Electricity: Movement of electrons, Current, Electric potential (voltage), Resistors and transfer of energy
P.EM.5: Magnetic fields
P.EM.6: Electromagnetic interactions
