  1. We did a flashlight activity using this website http://www.teachengineering.org/view_activity.php?url=collection/cub_/activities/cub_electricity/cub_electricity_lesson05_activity2.xml

    The students have a hard time getting all the wires to stay connected.  We worked with fourth graders and the would get frustrated even though they were very patient with their activities.  

    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.
