• 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
• We ca
