Digital Agenda October 7: Magnetism Cornell Notes

Standards:
MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.



Objectives

·        1. Define magnetism, and explain how magnets attract objects by watching a video, taking Cornell notes, and passing a post-quiz with a 3 or better.

1. Do Now: Intro to Magnetism Pre-Quiz




Independent
1. Title Your Cornell Notes, "Magnetism Cornell Notes" and set them up (Due Friday). (In order to leave, you must have ALL of the vocabulary done, and the questions answered up to #4. the rest is HW if you do not finish)

Questions
1. What is a magnet?
2.  List 3 metals that magnets are attracted to.
3. Compare and contrast the arrangement of the magnetic domains inside of normal materials, and the arrangement of the magnetic domains inside of magnets.
4. Describe what happens when all of the magnetic domains inside of a material are all facing the same direction.
5. When the magnet comes in contact with the paperclip:
    a) what happens to the magnetic domains in the paperclip?
    b) why does the paperclip temporarily become a magnet?
    c) Draw a model of the paper clip before, during, and after it comes in contact with the magnet.
6. How does distance affect how strongly a magnet attracts a metal?
7. What happens when a North and South pole come into contact?
8. What happens when two North Poles come into contact?
9. What makes magnetic Metals different from other metals?
10. Explain how compasses work.
11. Explain how electromagnets work, and draw a model.

Summary: Today I learned.....

Optional (ONLY AFTER YOU ARE FINISHED!!!!)
1. Play with this PhEt simulation to explore how to create electric and magnetic fields

2. Watch THIS MYTHBUSTERS EPISODE that tests whether or not an electromagnet can deflect bullets.

3. Watch THIS DOCUMENTARY about how magnets work

4. Play the roller coaster building game
