LESSON GUIDE

STEP 1 : Don’t Come a Knockin’

Don't Come a Knockin'1

Students will attach battery to power source. Wires are then added for length (creators choice), add button, then more wires (this time a must). Carefully make a cut in along the bottom of a Solo plastic cup and thread wire in, attach to buzzer inside of cup. Thread another wire into cup attaching to the other side of the buzzer. Finally attach that wire (or add more) to the number bit. Make sure the number bit is set to count and not to read.
