Basic Circuit
Build a Basic Circuit
Work in pairs (partners)
1. Collect your supplies (one set for each pair)
- one - Light Emitting Diode (LED)
- one - 9 volt battery
- one - 9 volt battery connector
- one - container of Play-Doh
- one - small piece of aluminum foil
2. Create a basic circuit
- Connect wires using pieces of Play-Doh. Just push the wires into the Play-Doh.
- Play-Doh happens to be conductive which means it allows electricity to flow easily.
- If the LED doesn't light try switching the wires.
3. Add a switch
- Use the piece of aluminum foil to create a pressure sensitive switch. Push on the switch to turn the LED on.
4. Experiment with different types of circuits
- Partner with other teams to build these circuits.

Makey Makey LABZ - Simple Circuit Challenge
Colleen Graves has created and shared a wonderful "simple circuit challenge" HERE.
Watch the 2 min. 26 sec video below to learn what a circuit is.
Watch the video below to further understand what a simple circuit is.
What is electricity? Watch this video.
Causal Patterns in Simple Circuits is a set of lessons that are to be infused into a broader unit on simple electrical circuits. The lessons are designed to address a set of persistent misunderstandings that students have when learning about simple circuits. Developed by Project Zero at the Harvard Graduate School of Education.

Sources for Materials used in "Build a Basic Circuit"
- Supplies (one of the following for every two people):
- LED - Lighthouse LEDs 10 x 5mm 9v Pre-Wired Red LED - Ultra Bright (7v, 8v, 9v)
- 9v battery - The link takes you to the amazon website to purchase their "basic" brand but you can buy these anywhere.
- Connector for 9v battery - Uxcell Black Red Short Cable Connection 9V Battery Clips Connector Buckle(10-Pack)
- Play-Doh - Regular off the shelf play-doh used to facilitate connections of wires. I like to buy the "Play-Doh Party Bag Dough, 15 Count (assorted colors)"
