What i am going to tell you is what i learned this science lessons or chapter. Hear are the somethings i learned. What i learned is that when a hot or warm particle hits a cold particle it becomes hot like them and move fast as the hot particle .i also learned about heat, heat is the flow of energy from warmer matter to cooler matter. When particle's lose energy the will contract and when particle get more energy it expands. Ironing clothes is conduction. What i liked in this chapter is the experiment's we did in class or out in the pod. In the chapter i didn't dislike anything at all! That is what i learned in this chapter!
