Below you will find your DDE group projects by Week. Included is your
presentation date and Quiz responsibility. Your group needs to meet with
Prof. Walker no later than the Tuesday of the week prior to your DDE Week.
At that time, you will need to turn in 2 potential quiz questions. We will
also discuss the details of your presentation. If you have anyquestions,
feel free to contact me. You need to send me an email verifying that you
are participating in the DDE group.
- Week 2 Human Reaction Time (10/7; Quiz 2)
Caudill,Henderson,Wilborn
- Reaction Time Project: Using a meter (or yard) stick record the
human reaction time by dropping and catching the stick and converting
the distance the stick fell into a time. Record the time for each attempt and
graph the results. Calculate the average and characterize the distribution.
Are there any biases in your data set? Make careful notes about how
you decided to do the experiment and average the data. Be prepared to
compare your data to that of Week 2's analysis. Are the results consistent?
Why or why not?
- Week 3 Human Reaction Time (10/7; Quiz 3)
Wagner,Strols, See,
- Reaction Time Project: See above. Your group should do the project
indenpendently and then get together (prior to 10/7) with Group 2 to
compare results.
- Week 4 Football Dynamics (10/21; Quiz 4)
DeGeronimo, Sakada, Tillman, Powell
- Your group should use the results of projectile motion to describe
the motion of a football. While you do the analysis, think about what
can enhance the motion and thus under what conditions your results apply.
The goal is to estimate the minimum initial velocity of a ball which travels
60 yards in the air. Your presentation needs to describe projectile
motion and show the results. You can get info on projectile motion from
Galileo himself.
Also, look at
water balloons and
trajectory plotter for help.
- Week 8 High Tension Wires and Cancer(11/18; Quiz 7)
Donatone,Morrell,Fuquen
- Groups from Week 8 and Week 9 are to present a discussion
of the possible connection between increased cancer rates and the proximity
to EMFs (high tension wires, cell phones, ...). You will need to read,
summarize, and present to the class the information found in ``EMF Handbook''
by S. Prata, pp.183 - 243 in your Course Note Packet. You should also
see if you can find studies, both pro and con, relating cancer rates and emfs.
- Week 9 High Tension Wires and Cancer(11/18; Quiz 7)
Koshino,Choi,Jefferson
- See Week 8.
- Week 10 Home Appliances (12/2; Quiz 8)
Carine,Wimite,Hibner,Ziegler
- Your assignment is to discuss how electromagnetic fields/radiation
(emf/r)
contribute to technology. Each group needs to pick a set of devices (2 or 3
per group) that
depend on emf/r (e.g., radar detector, electric guitar, cd player, ...)
and present your findings to the class (about 5 minutes per device). Check the following
for starters: How Things
Work, How Stuff
Works, or How Things
Work: The Physics of Everyday Life, by Bloomfield.
