At the 2004 MAA Southern California Spring Meeting
Three Bakersfield College Math
Students presented poster projects at the Mathematical Association of America (MAA)
Southern California Spring Meeting at San Diego University on March 6,
2004. Bakersfield College accounted for
five of the 30 poster projects and was the only community college that had
students participate in the session.
Other participants were from CSU’s, UC’s, and fouryear private
colleges.
Hesham and Sam are explaining their
project to a conference attendee. 
In this project, we investigated whether the ozone hole is healing or not. This study has been done using data that has been collected from reliable resources. By plotting the zone lost in Dobson units versus time, we derived several equations using a variety of mathematical means. Looking at the area of the ozone hole was not enough to understand its behavior, so we considered the thickness of the ozone layer. Faculty Advisor: Becky Head

Why
Don’t My Students Come To Class Everyday?

Adult ESL student attendance is often irregular. This leads to many frustrating moments for the teacher and the students. Why do adult students miss class so often? Which students miss class and/or drop most often? The presenter will discuss the results of a study she conducted to find the answers to these questions. She will show how data on students’ educational backgrounds, work schedules and family lives correlate with their attendance/attrition, and, in turn, their CASAS posttest scores. Students’ selfreported reasons for absences and drops will also be included in the discussion.

Roller coasters are exciting contraptions full of loops, curls, and extreme gforces. This project models a roller coaster by using fundamentals of physics, differential equations, linear algebra, and calculus. I designed my own coaster incorporating a drop and a loop. Using the path I derived for the coaster, I calculated maximum velocity and acceleration.

Derek’s project won the first place award of Best
Project.

Ion engines are the propulsion systems of tomorrow. Using data from the ion engine systems of Deep Space One and math from various levels, I will compare and contrast the Newtonian and the relativistic methods to calculate the time to reach 200,000 km/sec, and show when the two methods become noticeably different.

Minimum
Arc Lengths on a Doughnut

The purpose of this project is to determine whether ants will find the shortest path from one side of a doughnut to the other. Data was gathered by placing a plastic doughnut between the ants’ nest and sugar water. Points from the ant trail were used to generate an equation in 3D of their path. The arc length of this equation was then compared to that of other possible paths.
