Introduce the statement to be investigated in the lesson: Objects can be classified as conductors or insulators of electricity.
Display and discuss slides 10-12. Draw attention to the diagrams and consolidate the concept that a material’s conductive capabilities relate to the properties of its electrons.
Refer back to the video. Review how objects were connected to a circuit to confirm their conductivity.
Distribute the Electrical Conductors and Insulators Worksheet to the students. Read through the instructions on the worksheet as a class and check that the students understand the task. Have the class assist in gathering the required equipment.
Monitor and support the students as they complete the activity. The task can be completed in small groups or individually, depending on the resources available. Encourage the students to complete the questions on the worksheet once all of the tests have been completed.
After the activity has been completed, review the task and encourage the students to share their findings.
Refer back to the statement being investigated: Objects can be classified as conductors or insulators of electricity. Discuss whether or not it is true, using the results from the activity to support a conclusion.
