Demonstration on the different phases of matter
Procedure:
A.Place the popcorn-butter mixture (frozen) in a beaker and heat it until the butter melts.
B.Pour the melted mixture to and from two beakers.
C.Heat the liquid mixture until the popcorn begins to pop. (do not cover the beaker)
Type your responses to each of these questions on the next five slides.
1.What does the butter represent?
2.What do the popcorn kernels represent?
3.What caused the mixture to melt?
4.What must be done to the mixture to cause it to solidify?
5.When the popcorn popped and exited the beaker, what did it represent?
