Three things i learned about in this unit is conduction. Conduction is the flow of heat, direct contact between the obejects. Another one is a conductor. A conductor is a substance is energy that travels easily. Also i learned about is convection. Convection is the flow of energy that occurs when warm liguids or gas moves. The best thing i liked in this unit was the lab we did that was putting the plate down on a flat surface and then having water and dye on the plate then taking a candle and lighting it, and putting a vase on top of it and watching to see wat happend. There was nothing in this unit i disliked about. What are two good conductors?
