This assignment can only be completed using the link that is provided on Canvas (see
Modules). Use the blue menu bar on the right hand side of the activity screen to help guide
you through the portions of the activity we are completing. Begin by reading the
Introduction. The activity will run through Electricity and Magnetism. Fill out the
worksheet as you go, be sure to try all of the experiments presented in the activity.
1. Introduction (no questions here)
2. Magnetic Behavior
1) What is magnetism?
2) What is a magnet?
3. Magnetic Properties
1) What is happening when you cut the magnet?
4. Review of the Atom
1) What are the two types of motion that the electrons of an atom exhibit?
2) Which scientists model of the atom do we generally depict?
5. Creation of Magnetic Fields
1) What is a magnetic field and how is it created?
6. Electron Pairing
1) What are paired electrons?
2) How do paired electrons affect the magnetic properties of a material?
7. Magnetic Domain
1) What happened to the piece of metal when you rubbed a strong magnet across it
the first time?
1a) The second time?
2) What do the arrows in the material represent?
3) Why do they become lined up when the magnet is brought in contact with the
metal?
4) If you wanted to turn a paper clip into a magnet, how do you think you could do
it?
8. Two Ends of a Magnet
1) What happened to the blue pole of the compass arrow then it wa brought close to
the north pole of the magnet?
2) What happened to the blue pole of the compass arrow then it was brought close
to the south pole of the magnet?
3) What is a compass and what direction does it always point?
4) What would you expect to happen if a magnet is suspended by a string and
allowed to hang freely in the air?
5) From your observations, what can you conclude about the Earth’s magnetic
properties?
9. Magnetic Lines of Force
1) What happened when you placed the circular piece of metal in the magnetic lines
of flux?
1a) outside the lines?
2) What do the lines around the bar magnet indicate?
3) If he Earth is like a huge magnet, with a magnetic pole at the north end and
another magnetic pole at the south end, what might these imaginary lines look like
around Earth.
10. Magnetic Fields
1) What is happening when iron particles are sprinkled over and around the
magnet?
2) Do you see any differences in the patterns in each of the three situations? If so,
what differences do you see?
3) What do the patterns indicate in each situation?
4) Can you tell by these patterns where the magnetic forces might be the strongest?
4a) the weakest?
5) Can you tell by these patterns where the magnetic forces are attracting?
5a) repelling?
11. Ferromagnetic Materials
1) What is happening in this experiment?
2) What conclusions can you draw about magnets and magnetism from this
experiment?
12. Electromagnets
1) Explain how can turning on the electricity allow the iron crane to pick up the car?
13. Electricity and Magnetism
1) What happens to the compass needle as the compass moves around the wire
carrying electrical current?
2) What causes this to occur?
