Tips and Strategies

Below are some general tips and suggestions to assist with the management of materials for the Electrical Circuits Unit:

• Check here for classroom supplies needed for the lessons. Use the following strategies to make acquiring and maintaining these materials less cumbersome:
  1. Use your school’s Open House/Parent Night to gather materials for the unit. Download the Request for Materials form, copy in needed classroom materials, and distribute the form during this time.
  2. Store classroom supplies in one or two boxes.
  3. Organize classroom supplies and ExploraGear items needed for a lesson (or week) into a separate “Active” box, so they are ready for use.
1. Rotate the “Active” box items throughout the unit.

• Obtain these recommended books for the unit.

Electrical Circuits Lesson 3

The following are instructions to help you prepare the wire in Lesson 3 of the Electrical Circuits unit. They replace the first Preparation step on page 54 of the Teacher Lesson Manual. Use these instructions and the ExploraGear items below to prepare the wire.

Item	Quantity	Notes
Wire, 22-gauge, insulated	15 cm (6 in) per pair	To use with battery and bulb.
Wire stripper	1	To cut and strip wires.

1. Cut the wire into 15 cm (6 in) lengths.
2. Use a Philips head screwdriver to set the small nut and bolt on the handle of the wire stripper to about the third mark from the right end of the scale.

1. Strip about 1 cm (1/2 in) of the insulation from both ends of each wire. Some trial and error may be necessary to ensure the insulation is cut and not the wire when it is placed in the notch of the cutting blades.
