Circuit Challenge – Lab

Your teacher needs to approve your circuit before you move on to the next challenge.

REMEMBER…only TWO wires should be connected to the battery and no more.

  1. (1-1.5V battery, 1-1.5V Light bulb, wires.)  Without using a light bulb holder or a battery holder, figure out how to light the light bulb.
  2. (1 battery, 2 light bulbs, light bulb & battery holders, wires.)  Build a circuit so that if I unscrew one light bulb the other goes off.  You have just connected the two light bulbs in series.
  3.  (1 battery, 2 light bulbs, wires.)  Build a circuit so that if I unscrew one light bulb the other stays on.  You have just connected the two light bulbs in parallel.
  4.  (1 battery, 2 light bulbs, wires, switches.)  To circuit #3, add a switch to control each light bulb and a switch to control the entire circuit.
  5. (1 battery, 3 light bulbs, wires)  Build a circuit with two light bulbs connected in series and one light bulb connected in parallel.
  6.  (1 battery, 1 light bulb, wires, 1 motor)  Build a circuit where the battery, light bulb, & motor are connected in parallel.
  7. (1 battery, 1 light bulb, wires, switches, 1 motor)  Build a circuit where the battery, light bulb, & motor are connected in parallel.  Add switches to control the motor and the light bulb.
  8. (1 battery, 1 light bulb, wires, 1 switch, 1 buzzer)  Build a circuit where the light bulb & buzzer are connected in parallel.  The buzzers are directional; the black wire needs to be hooked up to the negative terminal and red wire to the positive.  Add a switch to control the buzzer.  DO NOT ALLOW THE BUZZER TO BUZZ CONTINUOUSLY!
  9. (1 battery, wires, 1 switch, 1 buzzer, 1 motor)  Build a circuit where the battery, motor & buzzer are connected in parallel.  Add a switch to control the whole circuit.
  10. (2 batteries, wires, 1 LED)  Connect two batteries in series.  Add one LED.  The LEDs are directional… the longer wire needs to be attached to the positive end of the battery and the shorter wire to the negative end.
  11. Congratulations you have finished!  You may now build your own circuit but using ONLY ONE BATTERY.

 

 

Clean Up

Everyone participates & you will only be allowed to leave when everything is put away properly.

  • Disassemble ALL materials & return to proper bin.

    Text Box: Text Box:

  • Clip wires to bottom of hanger & make sure alligator clip is pushed right up to the hanger:

 

 

  • Check the floor & desk around you for dropped equipment

I like how the kids have to figure out each of the circuits.  Great idea with the hanger.
