This document describes a lesson on the phases of matter. It includes objectives, definitions of matter and the three phases (solid, liquid, gas), an activity to classify materials as solid, liquid or gas, comparisons of the different phases, descriptions of phase changes like melting, freezing, evaporation and condensation, and questions about a video on phase changes.

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?

The ice would turn to gas without passing
through the liquid state. Heating the solid would
cause the intermolecular forces between the
molecules causing them to separate very
