We gave a short presentation on basic electronics, resistors, and circuits.  This was followed with an activity where students decoded resistors, measured actual values and calculated differences to validate tolerances. The activity is learning about resistors and Ohm’s law. 

Each student was given kit with multiple resistors and asked to read the color codes to determine the value and tolerance, and verify with a multimeter.  

We then made a circuit with a resistor, LED, 9-vlot battery, switch, and a breadboard to turn on the LED.

The students were very engaged and excited when their LEDs turned on.
