Properties of Matter
What ARE PHYSICAL properties?
The characteristics that we use to identify matter and distinguish them from one another are called properties. Some examples of physical properties are:
It does NOT matter how much matter you have, it will ALWAYS have the SAME boiling, melting, and freezing points!!! The amount of time changes depending on the amount of matter not the melting, boiling, and freezing points! Mr. Edmonds song about properties mass Mass is......
Test your skills using the Interactive below: Reading a Triple Beam Balance This is a Triple Beam Balance. We use this to measure the amount of MASS an object contains. |

Density
At a 5th grade level you need to compare objects by their ability to sink or float in water. Example: 1 cubic unit of IRON is denser than 1 cubic unit of ALUMINUM. The space or volume is the same, yet IRON is denser than ALUMINUM because the particles are packed closely together. Therefore IRON is also heavier per cubic unit than ALUMINUM. |
Solubility
Solubility is the ability of a substance to be dissolved
Soluble-------> Dissolves
Insoluble-------> Does not dissolve
Our substances on the right are salt coffee and sugar.
Do you think these substances dissolved in the water?
Water soluble materials will completely dissolve, which means the material will be distributed evenly throughout the water.
Consider this question.......................
In an experiment in the science lab, salt was poured into a beaker containing 200 Ml of water. The solution was stirred, and the salt dissolved.
Is salt soluble or insoluble in water???

Magnetism - Three common types of metals that interact with magnetic fields.
1. Iron
2. *Steel (alloy)
3. Colbalt

Like poles REPEL, opposite poles ATTRACT
Attraction - pull
When two magnets or magnetic objects are close to each other, there is a force that attracts the poles together.
Repulsion - push
When two magnetic objects have like poles facing each other, the magnetic force pushes them apart.

- Magnetism is the force of repulsion (pushing) or attracting (pulling) between two poles of a magnet
- Every magnet has a magnetic field around it
- Earth is a huge magnet! its magnetic field causes compasses to point North
- Not all metal is attracted to a magnet
- Iron, cobalt, nickel, and steel* are all attracted to a magnet, copper and aluminum are NOT!
