Power's Path

We think wood is the better conductor because wood catches fire very easily. We think rubber is a good insulator because we see electricians wearing electric gloves when working and never get shocked.

Copper and steel have a high rate of electricity currents to pass through it. Wood, lapis lazuli, rubber, and plastic have a rate of zero for electricity to pass through it.

Manipulated Variables: Different materials being tested

Constant Variables: Same buzzer, Same fan, Same switch, Same wires, Same LED light, Same temperature, Same circuit

Responding Variables: Effect on the electrical apparatus

1. Connect the wires to wood and make it a closed circuit.

2. Observe the working of LED/ Fan/ buzzer and note down the readings.

3. Repeat steps for 3 trials.

4. Repeat all the above steps with lapis lazuli, copper, steel, rubber, and plastic.

We are wrong about wood as we thought it is a conductor but it is actually it is an insulator because electricity did not pass through it when we tested in our design. We are right about rubber and it is an insulator as electricity pass through it.

Material | Trail 1 | Trail 2 | Trail 3 | Average

Wood | Not Working | Not Working | Not Working | Not Working

Plastic | Not Working | Not Working | Not Working | Not Working

Lapis Lazuli | Not Working | Not Working | Not Working | Not Working

Copper | Working | Working | Working | Working

Nail | Working | Working | Working | Working

Rubber | Not Working | Not Working | Not Working | Not Working

Every time when we put the wires on Copper and Steel (Nail) the LED bulb, Fan, and the DC Buzzer worked. When ever we put the wires on Wood, Rubber, Lapis Lazuli, Plastic the LED bulb, Fan, and the DC Buzzer not worked.

We found out that Copper and the nail acted as conductors because electricity passed through them, while wood, plastic, lapis lazuli, and rubber acted as insulators because electricity did not pass through them.

The result of the our science project can help many people in a variety of reasons and different ways. In our daily life, conductors play a very important role. Conductors pass power from the smallest gadgets to the largest machines. These materials light up our homes, keep our devices running. Insulators keep us safe and protected in everyday life by stopping unwanted flow of electricity and heat. They are key to many aspects of our daily lives and play a major role in everything from cooking utensils to the insulation in our walls.

We would like to thank our parents who helped us throughout this project. We would also like to thank our science teacher who guided and corrected us in different ways.
