Magnet Basics
What are the two ends of a magnet called?
Poles (North and South)
If a North Pole and South Pole are close, what happens?
They attract
What did Barry say about strong magnets?
They repel
What is a variable?
Something you change in an experiment
If two things change at once, is the evidence weak or strong?
Weak
Which poles of a magnet attract?
Opposite
If a North Pole and another North Pole are close, what happens?
They repel
What did Barry say about weak magnets?
They attract
What does "isolated variable" mean?
Only change one things at a time
If only one thing changes, is the evidence weak or strong?
Strong
Which poles of a magnet repel?
Same poles, Like poles
Which is stronger? attraction or repulsion?
They can be equally strong
Was Barry's claim correct?
Why is isolating variables important?
It makes evidence stronger
What surrounds a magnet and makes it work?
magnetic field
What happens when a magnet breaks in half?
You get two magnets, each half gets its own south pole and North Pole
Why do we test claims in science?
Too check if they're true
What happens if too many things change in a test?
You can't tell what change caused the result
Name one real life use of magnets
Compass, computers, speakers, fridge door decor
True or false: Weak magnets can still repel each other
True
Give one reason Barry's evidence was weak?
He changed too many variables
True or false: Evidence is stronger when variable are isolated
True
