• I learned that a marshmallow expands when heat gets into the little holes of the marshmallow.
• I also learned that the reason why a marshmallow turns black is because when the suger gets warm it turns black and makes the marshmallow swell a little bit.
• Marshmallows melt and expand because they have holes in them that lets in heat and gets all gooey but candy does not have as many holes so it does not expand and melt as easily and get all mushy and gooey.

3. HYPOTHESIS Maybe marshmallows expand when heat gets into the marshmallow and pushes the marshmallow around.

5. It is all gooey and mushy. One is really sticky and hard. It is crunchy and good. They are also very puffy.

I see that the inside is like a tanish color. The face is all messed up. They are now flat and hard but it is still a little gooey. And the marshmallow is sticking to the paper towel.

6. My hypothesis was almost correct. I learned that it turns because the sugar gets warm and the marshmallow gets all black. When the marshmallow was in the microwave it got all puffy because the heat made it such a big blob but, when I took the marshmallow out it started to go down and get flat. The marshmallow expanded in the microwave because when the heat got into the little holes of the the marshmallows it pushed the marshmallow all around. But if you put a piece of candy in the microwave it won’t expand and get all mushy because it does not have holes like a marshmallow does.
