The three things that I did learn in this unit are how radiation heats things up without the use of matter, How convection is not created by direct contact but how Pericles pass each other and making convection,and that heat will go up and cold will go down. What I did like best about this unit is that we did many experiments. My favorite was the food coloring experiment. What I did like least about this unit is how we had to do the home work. Even though they are needed. 

There are other things I did like about this unit like how we got to watch videos on it and many others. One question I do have is how does radiation not use matter?
