Additional Info

• ID Code: K7-05
• Purpose: Generate thought about how a motor works.
• Description: A 1.5 volt motor and 1.5 volt light bulb are wired in series such that a 1.5 volt battery can be connected across either of them individually, or across both in series. The first mpeg video linked below shows what happens when each is connected to the battery individually.
  Ask the students what will happen when both are connected in series: Will (a) only the light bulb operate, (b) only the motor operate, (c) both operate, or (d) neither operate?
  Again, only the motor spins, as seen in he second mpeg video below.
• Availability: Available
• Videos-1: Each connected indivudally
• Videos-2: Both connected in series
