Suggested Time: 50 minutes  
Grade levels: VI, VII , VIII
Overview:
This lesson demonstrates simple circuits and the differences between parallel and serial circuit design and functions. The Series and Parallel Circuits activity encourages students to test two different circuit designs through the use of low voltage light bulbs. Students work in teams to predict the difference between the two circuit designs, and then build examples of the two different circuits using wires, bulbs, and batteries. After testing several predictions about each circuit type, the students will compare results and discuss findings.
