EARTH’S MAGNETIC POLES – ARGUMENT AND EVIDENCE.
Oh no! Your crazy cousin is at it again. (He never was too bright.) He’s telling everyone he knows that the magnetic poles of the Earth will reverse and all life as we know it will END! He’s got the whole family in an uproar! What an idiot.
Fortunately, you have solid evidence – in the form of the articles you have read, and your textbook - that your crazy cousin is wrong, wrong, wrong!
Your assignment is to write a one-to-two page letter to your crazy cousin and tell him that although he’s correct that Earth’s magnetic poles do reverse, he’s got all the details mixed up.
Cover in your letter -
- Earth’s history of magnetic pole reversal.
- Evidence we have that pole reversals occur and how often.
- Who tracks the movement of the magnetic North Pole and why.
- Where the pole may end up in the next few decades.
- What happens at Earth’s core to create our magnetic field?
- How long these reversals take and what happens during them.
- Why we don’t have to worry, we’re really quite safe!
Neatness counts. Clarity counts. Spelling and grammar count. Back up your explanations with the evidence you find in your articles and textbook. 40 points.

Newton's Laws of Motion Model and Demonstration
For the next three days you will either work alone or with a team of NO MORE THAN THREE people in total to create a workable model of one of the laws of Newton's Laws of Motion. You will pick your primary law by drawing a slip of paper with its name from a bag.
- You will use materials we have in the classroom plus items you will bring from home.
- If you use things from the classroom, please ask me before you go cutting into them; I may still need them whole after we're finished.
- Think of the OK GO video, "This too shall pass" for inspiration.
- Needing/Getting is pretty darned inspirational, too.
Parents: This is a great time to use up small odds & ends you have at home and don't know what to do with: orphan nuts, bolts. ancient keys, long-ish bits of wire, small non-working electrical thingamabobs, leftover craft supplies like yarn, pipe cleaners, lollipop sticks, paper or plastic cups etc... send them to our class with your student! Small boxes, like shoe boxes or small shipping boxes are great, as well. We take donations of masking and scotch tape, too! And THANK YOU!!!
When you and your team (if you have one) are complete, you will use your model to demonstrate your law to me and to any volunteer students. You will then (1) explain how this model demonstrates/models your Law; (2) explain how it also demonstrates the other two Laws; and (3) explain how gravity factors into your demonstration.
- Tuesday 1/9/18: Receive Law; assemble team; discuss model designs; research on internet.
- Wednesday 1/10/18: Bring in materials if needed; assemble model.
- Thursday 1/11/18: Complete model; practice demonstration.
- Friday 1/12/18: Complete model & rehearsals, give demonstration to Mrs. Greenberg
