Learning objectives
Activities (in brief)
State the distinguishing properties of solids, liquids
and gases
Relate the properties of solids, liquids and gases to the
forces and distances between molecules and to the
motion of the molecules
Interpret the temperature of a gas in terms of the
motion of its molecules
Show an understanding of the random motion of
particles in a suspension as evidence for the kinetic
molecular model of matter, and, describe this motion
in terms of random molecular bombardment

moved by light, fast moving molecules
Revision molecular (particle) model of solids liquids & sgases
from KS3.
