Student Exploration: Magnetism
Vocabulary: attract, bar magnet, ferromagnetic, magnetize, north pole, repel, south pole
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. What happens when you place two magnets close together?
they come together
2. What objects do magnets stick to? Make a list.
anyhting that has iron, nickel in it
3. What do these objects have in common?
they are both metals
Gizmo Warm-up: What is attracted to magnets?
A bar magnet is a simple rectangular magnet. If you
hang a bar magnet by a string, the north pole (N) of
the magnet will tend to point north while the south
pole (S) of the magnet points south.
1. Look at the materials at the bottom of the Gizmo.
Which ones do you think will stick to a bar magnet?
nickel, copper, iron
2. Ferromagnetic materials are strongly attracted to magnets. Drag a bar magnet and the
piece of nickel onto the scribbled line. Press Play ( ).
A. Is nickel ferromagnetic?
yes
B. How do you know?
because htye come together
3. Test copper, wood, glass, and iron. Which ones are ferromagnetic?
Iron only

, Get the Gizmo ready:
Activity A: ● Check that the MAGNETIC FORCES tab is
Attract or repel? selected.
● Click Reset ( ).
Question: How do magnets interact?
1. Observe: Drag two bar magnets onto the paper and press Play. Then click Reset. Change
one of the magnets (either from N-S to S-N, or vice-versa). Click Play again.
A. What happened the first time?
they come together
B. What happened the second time?
they go away from eachother.
2. Form hypothesis: Magnets are either pulled together (attracted) or pushed apart (repelled).
Based on what you have seen, when are magnets attracted and when are they repelled?
attracted when different poles are facing each other
repeal when they are facing the same poles
3. Predict: Based on your hypothesis, which pairs of magnets will be attracted to each other?
Which will be repelled? Record your predictions below. (Leave the result blank for now.)
Prediction Result
Left magnet Right magnet
(Attract or repel?) (Attract or repel?)
attract attract
repel repel
attract attract
repel repel
4. Run Gizmo: Test your predictions using the Gizmo. Record your results in the table.
5. Draw conclusions: Fill in each blank below with the correct word.
A. The south pole of a magnet is attracted to the North pole of another magnet.
B. The south pole of a magnet is repelled by the South pole of another magnet.
C. The north pole of a magnet and the north pole of another magnet will repel each
other.
