Demonstrating the concept of conducting or insulating electricity. Note: This lesson plan is designed for classroom use only, with supervision by a teacher familiar with electrical and electronic concepts.
Learn about the electrical properties of different materials.
Learn how conductors and insulators react to electric current.
Solve simple algebraic manipulations involving squares and square roots.
Learn to make predictions and draw conclusions.
Learn about teamwork and working in groups.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
conductors and insulators
circuits and current
making and testing predictions
Students test a variety of materials in a circuit to determine whether each item behaves as an insulator or a conductor. Students make predictions about each item and discuss the results in teams and as a class. Student teams also construct their own circuit tester using wires, batteries, and a bulb.
