The Ruining of Sugar

States of Matter: Part 2

Materials used: Sugar
                         Beaker
                         Buntzen Burner
                         Cup with Water
                         

In school we performed a lab relating to sugar. First we got a sugar cube and licked it. It tasted sweet. We were also supposed to observe it. It was hard, white and cubicle, unlike the marshmallow. Then we had to crush it and dissolve it into the water. It tasted like tea.

Our next lab involving sugar was to burn it. We observed it and crushed it, just like the previous one. However, this time we burnt it over the Buntzen Burner. It turned black, just like the picture. After it cooled down, our teacher, Mrs. Rousseau, had to break the beaker to get the sugar out. It was black, hard and sort of like a crystal now. Next we were instructed to taste it. It tasted bitter and disgusting, just like the burnt marshmallow, except worse.
As we burnt the sugar, only one item was left...... carbon. The carbon caused the bitter taste. That was a chemical change. The purpose of this lab was to observe a chemical change and physical change, and to show the difference between them. We were also supposed to seperate a mixture. This lab showed how chemical change can affect an original item. That is why we experimented with this lab.

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 :)
