Three things I learned were what an exothermic reaction was, what a endothermic reation was, and what an indacater is. One thing I learned was that a exothermic reaction is a chemical reaction in which more energy is given off than taken in(example:burning of wood). I also learned that an endothermic reaction is a chemical reaction in which more energy is takeni in than given off(example:a cold ice pack). The final thing I learned is what a indacator is. An indacator is a substancethat changes color at a certain range of pH values. One thing i liked is the lab when we used cabbage juice as an indacator, this was my favorite because we got to try and come up with our own pH values. My least favorite part was doing the study guides because it took me a long time to write and look up the answer in the book.

What was your favorite part of the lesson???
