Student's Guide

 

1. Welcome to the Recycler Project! The information provided in this homepage should help you understand the need of this project, as well as why we have decided to use oversized refrigerator magnets, instead of other types of magnets. You should also be able to graph some data on how the magnetic flux of these bricks decreases over time. You should also be able to figure out why it is important to know this information.

 

 

2. Realize, what you are studying here is REAL! This is an actual experimental project taking place at the Enrico Fermi National Accelerator Lab in Batavia, IL. This data was not nade up, and it even has some flaws in it (called experimental error)..you should be able to determine at least one or two points on your graph that belong to some erroneous data points.

 

 

3. You will need some background to do this project. Some knowledge of algebra is necessary (college algebra would be helpful, but not necessary). In physics, it would be extremely helpful to have some knowledge of magnets, but you can still do a good job without it.

 

 

4. If you have any questions, think about it first! Then, you may wish to consult a text book. After that, you may wish to consult a teacher. Finally, if all else fails, you can e-mail me at Tegan7@aol.com, or Dr. Jim Volk at Volk@fnal.gov. Dr. Volk and I are quite busy, and you should not expect an immediate response, however, we are both interested in helping students, and would like to hear from you! If in doubt, e-mail Tegan7@aol.com first.

 

5. If you live in the Chicago area, or will be visiting, you may wish to stop by the Leon Lederman Education Center, where you can learn about the activities at the lab, with some hands-on interactive displays. The Center is on the Lab property, but is open to visitors year round. Call (630) 840-8258 to make sure the Center will be open when you plan to arrive. You can also see some of the ecological restoration that is taking place on the lab. The lab has restored large areas of native Illinois prairie, and wetlands. There's even a herd of American Bison prowling about.

 

What should I do?

Go back to the first page, and go into the data section. You may want to copy the data, and then make a graph of Average Voltage Change vs. Time (Remember, in our experiment, we are measuring Voltage instead of Magnetic Field Strength, because it is easier, but to keep things simple, you may assume that voltage and Field Strength are proportional to each other). MAKE THIS GRAPH IN A LINEAR-LOG FORMAT.....THAT IS, THE X-AXIS MUST BE LOGARITHMIC, AND THE Y-AXIS MUST BE LINEAR. When you graph, choose a scale that will show as many of the points as possible (many of the points will be on top of each other). Check out the Teacher's Guide for some more hints!
