Brief Description Squishy circuits allows for students to make a simplified circuit using Playdough as wires.
Lesson Objectives: Students will be introduced to the concept of circuits and attempt to make their own circuit using a power source, conductive wires, and lightbulbs.
Materials Needed: -Playdough
-9V Batteries
-LED Lightbulbs
Preparation and Set Up: -Pack supplies. Ensure that there are extras of everything, in case a battery has died or some of the LEDs are not functioning properly.
-Arrange students in pairs.
-Distribute materials.
Necessary Background Students should be introduced to the concept of circuits as well as the necessary components to each circuit. What are some common circuits that we use every day? It may be helpful also to explain to them the properties of Playdough that would make it useful in a circuit.
Procedure
  1. Arrange students in pairs.
  2. Distribute materials.
  3. Allow students to spend some time trying to get the LEDs to light up themselves, offering guidance only when deemed necessary.
  4. If students are still stumped, it may be time to give hints to them as to why their circuit is not working. The most common issue is that the Playdough wires will be touching. Some groups may not even make two separate wires.
  5. Ensure students understand why their circuit is or is not working by the end of the activity (1-2 weeks, as you see fit).
