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. Note: This lesson plan is designed for classroom use only, with supervision by a teacher familiar with electrical and electronic concepts.       Vocabulary : SeriesParallelOpen circuitClose circuitLEDResistance Objectives:Students will Learn that different circuit designs result in different electrical behaviors. Students will Learn about current flow and the operational differences between series and parallel circuits.students will use of different electrical and electronics components like,bulb, resister, power supple and use of multi meter. Students will be able to measure voltage and current. Students will Learn to predict outcomes and draw conclusions. Students will Learn about teamwork and working in groups.
