• I learned that marshmallows expand because of the sugar.
• Also, the microwaves help too.
• There is air trapped in marshmallows.

3.  Hypothesis:  When the microwave gets hot, it helps it heat up.  Then the marshmallows start to expand.  Then the sugar helps the marshmallows expand.

5.  The microwave heats the marshmallows up. It tasted like it was hard.  It is hard on the outside.  It feels like it was very hard.

6. My hypothesis was partly correct.  The air trapped inside was heated and this made the marshmallow expand.
