Electromagnetic Fishing Derby
NAME: ______________________________________ CLASS: __________________ Electromagnetic Fishing Derby Goal: Build an electromagnetic fishing rod that can lift paper clips from one container and drop them into another. *The Team 1 Derby winner will be the student who lifts & transfers the most paper clips in one minute. Requirements: Complete this packet and a working electromagnet fishing rod. Worksheet 1 – DUE _________________ Worksheet 2 – DUE ____________________ Worksheet 3 & fishing rod – DUE ___________

Worksheet 1 – Planning for Your Electromagnetic Fishing Pole Directions: Use this worksheet to make a detailed plan for building your electromagnetic fishing pole. After you build a first model, testing and improving it will be important steps. As you make plans and build your fishing pole, keep in mind that you may replace some parts later. Introduction: The different parts of the pole are the rod itself, a metal core wrapped in wire and powered by a battery, and a switch to turn the electromagnet on and off. In the space provided, make a detailed plan for constructing your electromagnetic fishing pole and sketch your proposed design with labels. ITEM MATERIAL(S) Draw and label your design here: Pole Core Item(s): Shape: Battery Type/Size: How Many: Switch (include in sketch) Materials: How it works: Attachments How will everything be held together?

Name: ____________________ Class: ____________________ Worksheet 2 – Testing Your Electromagnetic Fishing Rod Directions: You will need to test your different versions of your fishing pole. Does one choice of core work better than another? Is a core with 200 turns of wire twice as strong as a core with 100 turns of wire? How will you measure the lifting ability of each fishing pole version? One way is to count how many paper clips it will lift at once. Another way would be to see how heavy an object your pole can lift. Use the table below to record the data on your tests. Remember to change only one variable at a time. Remember to consider the freshness of the battery in your testing. Description of Model Tested Example: Nail Core, 100 Coils, Tight and Neat Wind Results, Observations, and Notes Example: Picked up 12 Paper Clips, Some clips fell off when raised, light and hard to control. 1. 2. 3. 4. 5.
