 Going the Distance  Jimmy, Tiffani and Lance attempted to
determine the distance traveled by a golf ball as a function of the
speed of the club and the club used. They also compared the data they
collected to the model used by a laser swing monitor.
 To Teach or not to Teach; an Investigation into the Trends of the
Salaries of America's Secondary Teachers  Jimmy, Gary and Matt
used data (corrected for inflation) to estimate the future salaries
and lifetime earnings of gradeschool teachers.
 Condenser Bushing  Bridget, Jay and Jennifer discovered the
equation relating the radius of a condenser bushing and the electrical
charge to the field intensity surrounding the bushing.

1998 
 The Probability of Winning the Superbowl  Can we use team statistics through
the last week of regular play (such as rushing yards and pass completion percentage)
to predict the winner of this year's Superbowl? Keri Bailey and John Bush used logistic
regression to determine the most important team statistics for "predicting" the previous
Superbowl winners. They then used these statistics to develop a logistic model for
predicting the probability each team will win the Superbowl this year.
 The Perfect Bat  Melissa Rudy and Tommy Elliot first explore the relationship
between a female baseball player's build (height to weight ratio) and their batting speed,
and find a roughly linear relationship. (UTM's softball team was kind enough to be the
subjects of this trial.) They then seek the optimum bat for a player, based on the player's
batting speed and the "weightlength ratio" of the bat.
 Outbreak: Is this the End?  A severe pandemic in 1918 infected at least
onefifth of the total human population and took more than 20 million lives. Anisha Mabry
and Jerrica Wall estimate the number of sick, contagious, immune, susceptible and deceased
individuals at several susceptibility rates, then predict the daily population over the next
few months.

1997 
 Draining Oil  The students drained a cylindrical tank of oil through
a horizontal pipe and modeled the height of the oil in the tank as a function
of the oil's viscosity, density, and temperature.
 Parachutes  After making small parachutes and quickly learning
why parachutes have a hole in the center, these students added a hole,
then modeled the terminal velocity as a function of the parachute's radius
and load.
 Rat Trap Catapult  Using a catapult made from a rat trap, two different types
of projectiles were launched. A model was developed to find the optimum firing angle.

1996 
 Choose your Club Wisely  The distance a golf ball travels as a function of
type of club (wood, steel and titanium) and swing speed.
 Flight Time of Paper Helicopters  Flight time of a paper helicopter
as a function of the wing length, weight and height from which it is dropped.

1995 
 That's the Way the Ball Bounces  The height a basketball bounces as a
function of velocity and pressure.

1994 
 You Spin Me ‘Round  an analysis of how long it takes clothes
to dry in a dryer (does it take twice as long to dry a load twice as big?)
Pat used dimensional analysis to develop a mathematical model, then empirically
fit this model using data he collected by drying towels.
 Evaporating a Puddle  an effort to model the volume of a puddle
as a function of several variables including time, temperature and the
specific heat of the fluid. The students heated alcohol to get their
data that was fit to a mathematical model derived by a dimensional analysis.
 The Melting of An Ice Cube  beginning with a simple differential model, the
students then used dimensional analysis and least squares fit to determine the necessary
constants. The end product is a model that relates the mass of an ice cube to the
ambient temperature, time, specific heat and thermal conductivity of water.

1993 
 Free Style Tuning for Guitars  Determining how to tune a guitar
using string tension and linear density. By using a hook to hang a mass
on the string, these students model how many turns of the peg are necessary to bring
the string into tune.
 A Projection of the Deer Population  Using the Leslie matrix Model, the
students estimated the number of female deer in Tennessee over the next few years.
 The Effectiveness of a Foam Rubber Coolie  The rate of heat transfer was
related to the amount of the surface of the can covered by the "coolie," as well as the
specific heat of the soda, and the thermal conductivity of the foam in the coolie.
 A Spinning Dilemma  Farmers use paddlewheel spreaders to distribute
seed. This team modeled how far a "seed" (actually a marble) would
travel when dropped on to a spinning paddle as a function of the angular
velocity, height, gravitational constant, and radius.

1992 
 Let's Go Parking  The geometry of parking cars.

1991 
 The Average Number of Coins  If we always give the "best" amount
of money to the cashier, what is the average number of coins we will have
in our pocket? Are there other sets of coins (instead of 1, 5 10
and 25 cents) which would reduce this number?
 To Fold is to Conserve  How fast will a towel dry as a function
of both the humidity? And what is the best way to fold it on a clothes
line?
 To Play are not to Play; How Dangerous are Collegiate Sports 
Using data from the NCAA Injury Surveillance System, this team developed
a ranking of collegiate sports from the "most dangerous" (spring football,
wrestling and men's soccer) to the least dangerous (women's softball).
 Electricity, the Energy of Choice 

1990 
 Liquid DrainO  Models the rate a which a cylinder drains
as a function of the size of a hole in the base and the viscosity of the
liquid.
 Crime on Campus  Compares the crime rate on 150 college campuses
to the campus and city sizes, and the crime rate in the city.

1989 
 Milk Production in Dairy Cattle  Various data such as cattle age, somatic
cell count, and temperature are correlated to average milk production for one dairy
farm.
 Mathematical Relationships of Golf  Distance a golf ball travels as a
function of the face angle of the club and compression of the ball.

1988 
 To Cut or Not to Cut?  This project studied the relationship between a cut or
scuff on a baseball and its trajectory out o a pitching machine.
 Bowling Strikes  Using both a computer model and a mathematical model, this
group determined the best angle and location for a straight ball.
 Efficient Restaurant Service  A model of restaurant service as a function of
the distribution of the customers and the number of employees.
