Three things I learned in this science unit is that a room is heated by convection. Another thing I learned is that you boil water using conduction. The last thing I learned is that a microwave heats food by using radiation. The thing that I liked the best in this unit was doing experimemts. My least favorite thing about this unit was learning about expansion and contraction because that was the most confusing thing to me. The question that I have is where does a plane's jet get the heat from?
