1.Static Electricity Intro
-demos: rod pvc pipe, wool/felt, and paper, balloon on the hair paperclips
-Comment: We had planned on the kids all trying to make static electricity each with a plastic ruler. The plastic rulers did not pick up anything.
-powerpoint of circuit basics
3. Build A Flashlight
-introduce switches and bulbs
4. Adding more lightbulbs in a circuit
-explain current, energy dissipation
-craft activity that reviewed simple circuits. They built a card that incorporated a circuit with a battery and a light or a motor.

-application of circuits in everyday life
-making the circuits more compact for a device
We tried to make the circuit building easier by using christmas lights and cutting them up and exposing the wires like this http://www.stevespanglerscience.com/experiment/light-circuit-sick-science. We went through a lot of bulbs because they would burn out often using 9V batteries so it was useful to have a whole string of lights available and we could just strip more as we needed.
We also bought 6 of these switches https://www.sparkfun.com/products/9414 later in the semester which would have been good for this project so they are available in the supply closet now, check for them with the light bulbs.
5. Parallel circuits
-discovery experiment, how to keep one light on while turning one off
7. Potato batteries
-potatoes, lemons, oranges
