1. Properties of Matter

2. Mass How much matter is in an object.
An object’s mass stays the same no matter where it is
Tool- Triple Beam Balance or Double Pan Balance
Units- Grams (g) or Kilograms (kg)
“ I can classify these objects by which ones are more than 50g and which are less than 50g”

3. Practice finding Mass http://touchspin.touchspin.com/DisplayTBB.php

4. VOlume The amount of space an object takes up
Measure with “Z Factor” (LxWxH), use a graduated cylinder, or use water displacement
Solids, liquids, and gases take up space
“ These objects take up 50mL or more of space, and these objects do not”

5. Practice finding VOlume

6. Physical State Is your object a solid, liquid, or a gas?
Solid has a definite shape and volume
Liquids can have lots of shapes, but a definite volume
Gases can have lots of shapes, but no definite volume
“These objects are solids, and these others are not solids”

8. Changing states of Matter

9. Solubility Testing to see if an object dissolves in water
If something dissolves in water, it creates a solution
If something is not soluble it creates a mixture
Heat up the liquid to make substances dissolve faster
To separate a solution you must evaporate the water

10. Warm water helps substances dissolve faster
Stirring quickly helps substances dissolve faster

11. Magnetism The ability to be attracted to a magnet
Magnets have a North and a south end
Only opposite ends will attract
Most metals are magnetic (Iron, cobalt, nickel)

13. Density The amount of matter in a certain amount of space
Mass divided by volume
(More than 1 it will sink, less than 1 it will float)
If something floats it is less dense than water
If something sinks it is more dense than water

15. Conductors and Insulators
Conductors- Materials that allow electricity and heat to pass through them
Insulators- Materials that do NOT allow electricity or heat to pass through them
Use by testing circuits
