Conduction Activity by Tracy Nguyen [Student FVHS]

1. What is conduction? What is heat as defined in science?

Conduction is the transfer of thermal energy by molecular and electrical collisions within a substance. It occurs by means of particles in a solid, often electrons.

2. Explain how conduction is demonstrated by the experiment that you are doing with the candle, wire, and the wax.

The candle, wire, and the wax demonstrate conduction because the candle flame (thermal energy) at the hot end of the copper wire travels along the wire's length to the other end where ball of wax is placed. The thermal energy is expected to reach the end of the wire, to melt the ball of wax.

3. Which of the wires conducted heat the best (melted the ball of wax first)?

The thickest copper wire conducted the heat the best.

4. Explain with at least 2 sentences why that wire is the best conductor of heat. (Make sure to mention how the thickness of the wire helped your results)

The thickest wire is the best conductor of heat because the thicker the wire, the less resistance. Because the wire is thicker than others, the metal atoms have loosely held elections that are free to travel in the wire.

5. Which of the ESLR's was addressed in this activity. Explain with a couple of sentences.

Critical Thinkers was portrayed in this activity frequently because we developed educated opinions on what copper wire would conduct heat the best. We researched and processed information using our mobile devices and other technology. The entire class applied knowledge to achieve this activity.

Skip to 0:25 to view the ball of wax melting off the copper wire.
