Grade 5 Science · World 8: Circuit Works · Level 58
Conductors and Insulators
Test common materials and sort them.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 58
- Some materials let electricity pass easily. They're conductors. Most metals are good conductors.
- Others block it. They're insulators, such as rubber, plastic, glass, and dry wood.
- Test a material by putting it in a gap in the circuit. If the bulb lights, it's a conductor.
- If the bulb stays dark, it's an insulator.
- Try it with a grown-up: use your small battery circuit to test things from a junk drawer, and make a chart.
Georgia Standards of Excellence in Science:
- S5P2.c — Plan and carry out investigations on common materials to determine if they are insulators or conductors of electricity.
