Popcorn

We asked ourselves the question:

Can we change food by heating it?

Our hypothesis was that when popcorn is heated it will pop because all the molecules will start to move away from each other.

Method:

First we poured popcorn kernels into the popcorn machine and shut the lid.  

Then we turned on the popcorn machine.  

The machine heated the kernels and they started to pop!

We ate the popcorn. Yum!

The Results:

When we heated the popcorn it started to pop! We can change food by heating it. We can change other foods like ice-cream, water, bread and chocolate by heating them too.
