States of matter

Part 1: Marshmallow

Materials used: Buntzen Burner
                           Small Marshmallow
                           Large Marshmallow








 In class we observed different states of matter by burning a marshmallow. First however, we were given a small marshmallow. We had to observe it first. I concluded that it was small, white, and soft. Then we were instructed to taste it, which in my opinion, I enjoyed. I wrote that it was sweet and soft. Then, we received a large marshmallow, observing it as well. It was big, soft and white. Next, we had to burn the large marshmallow over the buntzen burner. We were instructed to eat the burnt part first. In my opinion, it was bitter and impossible to bear. However, the inside was heaven.

The reason we experimented this was so we could tell the difference between chemical and physical change. We were also supposed to observe the marshmallows change in matter. If I had kept on melting the marshmallow, it would have changed from solid to liquid. I believe we were supposed to realize that even though it was a minor part of this experiment. Due to this, I conclude that this lab was to help us observe matter and physical and chemical change. Possibly to relieve our appetite and help us remember also :)
