• I learned that popcorn has water in it.                
• I learned that popcorn pops because the heat makes it jump around and pop.
• Lastly, I learned that when popcorn gets so hot steam and water comes out.

 

  3.      My hypothesis: It pops because the heat pops it.

5.  I saw that the test tube burned and that steam and water came out. A cloud of steam traveled up the tube.

   

      

6.  I did not know that popcorn had water in it. I just learned that Friday. My hypothesis was half correct. It was half of how popcorn pops. It is like the water’s being boiled and the steam pushes the popcorn kernel and it pops open.  It was really cool to learn this and it was fun.
