"Conductors and Insulators" PPT courseware

Description

Hunan Education Edition fifth grade science volume 1, conductors and insulators PPT courseware

Part One: Circuit Detector

circuit detector

1. Why does the little light bulb light up?

2. If you cut the wires in the circuit, what will happen and why?

3. Is there any way to reconnect the small light bulb?

Use a "circuit detector" to detect whether rubber is a conductor or an insulator

1. Predict whether the rubber can pass electric current to make the small light bulb light up, and keep records.

2. Make the two detection heads of the "circuit detector" contact each other to check whether the small bulb emits light.

3. Use two detection heads to touch both ends of the rubber and observe whether the small bulb emits light.

4. Repeat the test once and record whether the small bulb is "on" or "off" during the test.

Conclusion: Rubber is an insulator.

Conductors and Insulators PPT, Part 2: Discussion

Five-minute discussion

1. Look for it: In our experimental classroom, look for where insulating materials are used in the electrical equipment?

2. Think about it: What is the purpose of insulators? What is the use of conductors?
