Conduction Activity by Bryan 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. Heat only 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

How conduction is demonstrated by the experiment is that the flame (thermal energy) travels through the copper wire. Then the heat travels through the copper wire to the other end and melts the wax.

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

The largest wire melted the wax first, therefore meaning the largest wire conducted 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 largest wire was the best conductor of heat because it was the thickest of the three copper wires. With more room for the thermal energy to travel, it would travel to the ball of wax faster, therefore melting the ball of wax first.

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

The ESLR, Critical Thinkers was addressed in this activity. Instead of doing a lab report on paper, we utilized current technology (padlet) to do our lab report instead. We also developed educated guesses and make well-informed choices on which copper wire would melt the ball of wax first.
