Magnetism

2. What are some uses for magnets?
LO: To know the responses of different materials to magnets
Magnets are in most electronic devices, in fact, anything that has a motor uses a magnet.
They are used to slow down roller coasters and subways.
Magnets are used to keep refrigerator doors closed.
Magnets are even placed in the stomachs of cows to catch metals!
Televisions, computers, and microwave ovens all operate with magnets.
More uses of magnets are found every day!

3. What are the characteristics of magnets?
LO: To know the responses of different materials to magnets
They have two ends called magnetic poles.
They can also
repel other
magnets.
They are usually made of iron.
They can attract some materials.

4. What do all these new words actually mean?

What do all these new words actually mean?
Magnet
A stone or a piece of metal that attracts some
other metal.
Attract
To pull towards each other.
Repel
To push away from each other.
Poles
The ends of a magnet.

5. LO: To know the responses of different materials to magnets
poles
Every magnet has at least one north pole and one south pole. 
The blue end of a magnet is usually the south pole.
The red end of a magnet is usually the north pole.

6. LO: To know the responses of different materials to magnets
When two magnets are close, they create pushing or pulling forces on one another.
These forces are strongest at the ends of the magnets. The two ends of a magnet are known as the north pole and the south pole.

7. LO: To know the responses of different materials to magnets
What did we find out?
So now we know that “like” poles repel each other…
and that “opposite” poles attract each other.
They do this because there is a
FORCE
between them.

8. LO: To know the responses of different materials to magnets
Same poles repel
LO: To know the responses of different materials to magnets
If you try to put two magnets together with the same poles pointing towards one another, the magnets will push away from each other. We say they repel each other.
In this picture two north poles are pushing away from each other (repelling each other).

9. Different poles attract
LO: To know the responses of different materials to magnets
If you put two magnets together with different poles pointing towards one another, the magnets will pull towards each other. We say they attract each other.
In this picture a north and a south pole are pulling towards each other (attracting each other).

10. LO: To know what is the difference between solubility and insolubility
Soluble
LO: To know what is the difference between solubility and insolubility
When a substance dissolves into another substance

11. LO: To know what is the difference between solubility and insolubility
Insoluble
LO: To know what is the difference between solubility and insolubility
When a substance cannot dissolve into another substance

12. LO: To know what the difference between irreversible and reversible
A Reversible Change
When a substance has changed state (eg. a solid piece of chocolate to melted liquid chocolate) It can be changed back after (reversed).

13. LO: To know what the difference between irreversible and reversible
Solution
When two substances are mixed they create a new substance.
For example you can have a salt solution.

14. Reversible or Irreversible
LO: To know what the difference between irreversible and reversible
Reversible or Irreversible
When a substance has been created it can sometimes be turned back into its original states
Sometimes when you have changed the state of a material, you cannot change it back to its original state

21. LO: To understand how distillation works
Distillation is a chemical process and it is a mixture made up of two or more liquids with different boiling points. This method has been used a long time for drinks.
