Part of Lesson Plan: **Fabricate a simple electrical switch (updated) by Ramon C. Iniguez

Activity Overview / Details

Show students examples of student work (see attachments) so that they have a model to base their idea to. Once the students have a clear understanding of the expectations, divide the class into groups and have them search the shop, or designated area, for insulators and conduction to fabricate their switch. Give each group two six-inch lengths of wire to attach to their switch. These wires will then be connected to a light and battery to test the function of their switch.

Caution!

Discuss battery safety, and any other safety issues that you find important, before allowing students to connect their switch and light to the battery.

Note: Before releasing the students to look for their materials, tell them that you want to see their materials before they start fabricating their switch in the event they have materials that you don’t want them to use.
