Possible Module Topic?

The past couple days have been pretty busy with research and reading.  I finished an Inquiry-based Learning Workshop I have been working on online.  I also think I have finally decided on a topic for my module.  After contemplating which math concepts I can apply to NASA in an interactive way, I have decided to relate basic algebra to the Crab Nebula's pulsar.  I am planning on beginning this module by reviewing pre-algebra topics, such as the definition of a function.  Then, I will display different graphs and ask the students to determine if they are functions or not.  Next I will describe pulsars and the Crab Nebula, giving a linear equation relating to the spinning of its pulsar.  I will ask the student to evaluate this equation in different ways and discuss how changing the slope would alter the graph's characteristics.
