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

Conduction is defined as the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.

A form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation.

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

The fire from the candle used conduction when it tranfered its heat to the wire and the wire transfered its heat to the fax causing it to melt and fall.

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

The thickest wire conducted the most heat because when it was transferring heat to the wax ball it had a lot more area to transfer the heat to the wax so it made it melt first.

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)

Wire is made from lattice of ions with free electrons. When it gets heated electrons collide with ions it gets kinetic energy making it move to the cold end. It collides with a cold ion making it vribatge making it heat up the end thus transfer heat across the wire.

During this project we learned how to be an effective communicator because this is the first project with new partners and we were able to do this project without any conflict with each other.
