One thing that I liked the best in this unit was the popcorn lab. I liked that a lot because I got to get popcorn. Another thing that I liked was when we were in the lab and were playing review games. The thing that I liked the least was when we had the test because it was kind of hard even though I studied a lot. Three things that I learned was what conduction, convection, and radiation. Conduction is when energy is traveling from one to another by direct contact. Convection is the transfer from on place to another by gases and liquids moving. Radiation is the moving of particles without the use of matter. I really like this unit. Did you like it?
