1. Properties of Matter

2. Properties of Matter Kinetic Theory of Matter
Law of Conservation of Energy
Law of Conservation of Mass

3. Kinetic Theory of Matter
All matter is made of particles called atoms.
These atoms are always in constant motion.
As heat and energy increase, motion of the atoms increases.

4. Kinetic Theory of Matter
Kinetic Theory of Matter can explain many everyday occurrences.
Increasing temperature causes solids to melt into liquids
Inflatable pool toys deflate in cold temperatures
Water and food coloring demo

6. Law of Conservation of Mass
Mass cannot be created or destroyed.
In a chemical reaction, the mass of the products will equal the mass of the reactants.
This is why we have to balance chemical equations!

8. Law of Conservation of Mass
You place 10 grams of ice in a beaker and let it melt. What is the mass of the liquid in the beaker?
Baking soda and vinegar experiment

14. Law of Conservation of Energy
Energy cannot be created or destroyed
Energy can change forms
Heat
Electrical
Chemical
Mechanical
Any more??

15. Law of Conservation of Energy
A car engine turns the chemical energy of fuel into mechanical energy.
As the car runs, much of this mechanical energy turns into heat.
Solar panels turn sunlight energy into electrical energy.
During a chemical reaction, energy may be transferred (absorbed or released) but it does not disappear.

16. Energy Questions What is the definition of energy?
Describe and give examples of two types of kinetic energy.
Describe and give examples of two types of potential energy.
Give an example of an energy transformation.
What does energy efficiency refer to?
Do you think a car engine is energy efficient? Why or why not?
If energy cannot be created or destroyed, why are we worried about running out of energy sources?

18. Foldable/Poster Guidelines
For each property of matter:
Define it
Draw it
Apply it (where can you see this in real life?)
