This document discusses different types of materials including plastic, paper, metal, glass, clay, rubber and wood. It describes various properties such as being smooth, rough, soft, hard, rigid, flexible, transparent, opaque, waterproof and absorbent. It also discusses how heating and cooling can change objects in reversible or irreversible ways and how forces can be used to change shapes through bending, stretching and squeezing or cause movement through magnetism.

6. Heating and Cooling things
We can HEAT or COOL things to change objects.
Changes can be REVERSIBLE (change back) or
IRREVERSIBLE (not change back)

7. We can make things CHANGE SHAPES
Bend
Stretch
Squeeze

8. We can make things MOVE (Forces)
MAGNET
We pull things TOWARDS us We push things AWAY FROM us
Some materials move towards
a magnet. MAGNETISM is a
type of force
