In this unit I learned that everything is made up of tiny particles. I also learned that most of our heat comes from the sun. Lastly I learned that conduction takes place throughout direct contact between two objects. What I liked most is the labs. My favorite one was the lab were we had to put our hand in cold water then into warm water. Then into hot water then back to warm water. My least favorite thing I learned in science class was convection, conduction, and radiation. I still dint really know what convection and radiation are but I have a good idea. OK, now for a question did you like this science lesson
