Instead of doing traditional problem sets and tests during the fourth quarter, I have kids work on an individual project on something that relates to multivariable calculus that interests them. (During the year, I have them keep track of interesting tidbits or facts or something I go off on a tangent about [pun] that they find could be a possible final project. I also have this list of ideas I’ve culled to help them come up with a topic.)

I have them come up with a prospectus and I individually talk with kids about their proposed project and timeline for completion. Then when they get started and start envisioning a final product, they are asked to write a description of the final product out clearly, and come up with a rubric for grading that product. They are also asked to make a 20-25 minute presentation to their classmates, their parents (if they choose to invite them), math teachers, and administrators. This year, they wanted to give their presentations during senior thesis week, which means that lots of their friends could come to their talks.

And they have been! In the past week, students have given their talks and I have been way impressed by them. Honestly they’ve been more independent than in years’s past, so I was unsure of whether they were putting together a solid final project or not. They did.

Without further ado:

**Title: Mathematical Change We Can Believe In**

Description: This presentation shows how one region can be manipulated to form something more interesting, a process called Transformation of Axes. The 2D and 3D analogues, use of rectangular and rounded shapes, and proofs of the properties of transformations abound in this exciting journey through the wonders of the world of multiple (MANY) variables.

**Title: Pursuit Curves: The Ultimate Game of Tag**

Description: Pursuit curves are the paths formed when one point chases another point. In this program, we will be looking at the mathematical explanations of pursuit curves, and then using a computer program I have built to model a few.

**Title: What’s Our Vector, Victor**

Description: This will be an investigation into the history, origins, and evolution of vectors, their analysis, and notation.

**Title: Economists working with Models: Understanding the Utility Function**

Description: Firstly, we will gain a foundational understanding of economics as a discipline. Secondly we will discuss the utility function and the questions which it raises.

**Title: From Chemistry to Calculus: a study of gas laws**

Description: For my project I have constructed a “textbook” that analyzes the idael and real gas law through the lens of multivariable calculus. In my “textbook” I compare and constrast these two laws by means of graphical and derivative analysis.

**Title: Knot Theory**

Description: Knots are everywhere around us, from how we tie our shoes to how the proteins in our body wind themselves up. My presentation will give an overview of their place not only in the “real world,” but also the world of classroom math and calculus.
