Properties of materials • hard materials

are very difficult to cut

• Soft materials are easily to cut

• Tough materials are very difficult to break fragile materials are easy to break

WHAT IS MATTER• AN ATOM IS THE

SMALLEST PARTICLE OF MATTER.

• A molecule is made when two or more different atoms join together.

Properties of materials• Plastic materials are easy to bend

elastic materials go back to their shape

Thermal conductors and thermal insulators

• Thermal conductors

• Its molecules are free to move about

• Thermal insulators

• Their molecules are close together and can’t move about

Mixtures and solutions• Heterogeneous

mixture• We can see the

separate subtances

• Homogeneous mixture
