Microsoft Powerpoint Presentation Week 8 - Squishy Circuits.pptx Powerpoint I used when I taught this lesson. Contains lots of animations - watch slideshow rather than looking through editing view if you want to use. Also blank 'circuits' slide was designed for drawing circuits using the smart-board May 09, 2013 by Matthew R. Long

  1. The students really liked this activity and we gave them some foam paper to work with. We taught them that the foam was an insulator so they could use it to separate the playdough and their circuits would still work.  They got really creative with their designs and used the foam and playdough to make designs such as a tower with a light on top and a car with headlights.  Our class is an hour long and the activity could have been shorter but we let them take more time by making them more creative.

    We did this activity as a final, fun one for the students. We did not have to spend time explaining what circuits were because the students previously had learned about circuits in class (which saved time).

    Overall, the project was successful. There were students who had trouble visualizing how play doh can be part of the circuit, so it might be helpful to have them draw out what a circuit looks like first and ask them "substitute" play doh for wires. We challenged the students who finished early to come up with even cooler, more unique designs. This was a quick, easy way to end the semester. 

    One tip: Paper clips can be substituted for alligator clips, though they are harder to latch onto the batteries.
