 physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. . What I learned from my project is that Pop Secret was the one with the least amount of popcorn. popcorn is a physical change because  Popping cone is a physical process, not chemical. This is because popping does not change anything in the internal or chemical environment of the cone, hence just a physical process. (kidclicks.org)

The people who invented the popcorn were the people in  Peru and they found this 3600 b.c. The Indians made popcorn through the 16th and 17th century. Corn was called maize by the U.S Indians ( popcorn wikepida).

 Corn kernels were very hard. So two make popcorn u need hot water and oil boiled to 180 degrees. Then the kernels would break and expand into popcorn. And also during the depression they bought a bag of popcorn that was 5 through 10 cents for a bag of popcorn.( popcorn wikepida)

The definition of popcorn is  A variety of corn, Zea mays everta, having hard kernels that burst to form white, irregularly shaped puffs when heated.( dictonary)
