Three things I learned in this unit are what the different ways heat can transfer from one particle to another.  The first way is radiation, it transfers heat by electromagnetic waves.  The second way is conduction, this is the transfer of heat with direct contact with two objects.  The last way is convection, this is the transfer of heat with the use of a liquid or gas.  What I liked best about this unit, was that almost everything we learned about we did some type of lab or experiment, where we got up and did fun stuff in groups.  I did not dislike anything we did this unit, i liked it all.  Can you tell me what a conductor is?
