Magnets have two poles. What are the poles called?
What is the rule that tells if the poles will repel or attract?
North and South Pole.
Rule: Opposites attract!!

TRUE OR FALSE: All magnets have the same strength and can pick up the same magnetic objects.
FALSE: We know from our experiment that different magnets have different strength.

In class, we did an activity that helped us explore which objects were magnetic and which ones were not. What activity did we do for this?
We sorted objects based on "Magnetic" or "Non-Magnetic" and then we tested them and glued them into our science journals.

A.) Hockey Stick
B.) Your Brain
C.) Compass
D.) Tire of a Car

Is a pencil magnetic?
No! A pencil is made out of wood and lead.

Which magnet do you think would be stronger? A whiteboard magnet or the magnets we used for our science projects?
Science project magnets!

TRUE OR FALSE: The word "repel" means that a magnet is broken and will not stick to other magnets.
FALSE: Repel means when magnets push away from each other because the poles that are coming together are south and south, or north and north.

In class, we learned that magnetic fields can pass through objects. What were 2 objects the magnetic field passed through, and 1 that it did not?
Passed through: fingers, deck of cards, wooden block, tin foil
Did not pass through, soccer ball, science journal

Why does a refrigerator need a magnet to function correctly?
The magnet keeps the door shut so that the cold air does not escape. If there was no magnet, the food inside would get warm.

Is a computer magnetic?
Yes! Computers have parts inside that are made out of iron and steel that would attract magnets. DO NOT PUT MAGNETS NEAR A COMPUTER!
300
Why do the poles of a magnet matter? What do the poles tell us about how the magnets will interact?
It is important to understand that magnets have poles because they help us understand why magnets can attract other magnets or repel other magnets.
300
TRUE OR FALSE: Magnetic fields can pass through some objects. This means that some magnets can attract together even when there is something that is between them.
TRUE: What are some objects we know that magnetic fields can pass through?

Tell us two new things that you learned about magnets that you did not know before?
YAY! You thought of two things:)

How does a compass work? What direction does the magnet inside always point to?
Inside of a compass, there is a magnet that always attracts to the north pole of the earth! The needles always points NORTH!

Is Ms. Munroe's finger magnetic?
No! There is nothing metal in my finger! But magnetic fields can pass through fingers!
400
Why do you not want to put a magnet close to a computer or any kind of electronic device?
Because the device has parts inside that are made of iron or steel and the magnet will attract them, causing them to break off of their correct place.

TRUE OR FALSE: A paperclip is a magnet.
FALSE: A paperclip is MAGNETIC, but it is not a magnet itself.

In science, we learned that not all magnets have the same strength. How did we test this?
We used a ruler and had a paperclip at the end. We slid that magnet down the ruler and recorded which number the magnet was at when the paperclip attracted to the magnet.

An MRI (Magnetic Resonance Imaging) machine uses magnetism to work. What is an MRI machine used for?
Doctors use an MRI machine to look inside peoples body's without using surgery. It is similar to an X-RAY of your bones.

Is a spoon made out of silver magnetic?
No! Only spoons made out of iron or steel would be magnetic.

There is a rock that occurs naturally on the earth that is magnetic. What is this type of rock called?
MAGNETITE. It is a rock that has iron in it!

TRUE OR FALSE: If you wanted to create a car that is powered by the magnetic force, you would want to put the north pole facing out on the back of the car, and the north pole facing out on the driving stick
TRUE. If you do this, the magnets will REPEL and push the car forwards.

In science, we used a special black powder for an experiment. What was the black powder made of, and what did the powder show us?
The power was Iron Filings. The filings showed us what a magnetic field looks like.
