You can also evaluate popcorn quality by measuring kernel expansion, which means how big the popped popcorn flakes get. Students will learn how to make popcorn by using three types of heat transfer. Once the pressure gets high enough and the temperature reaches about 180 degrees Celsius (355 degrees Fahrenheit), the kernel hull bursts and the popcorn is turned inside out.
