Objectives
This unit is designed to teach Mathematics objectives relating to scientific notation, equation solving, the Pythagorean Theorem, units of measurement, writing formulas as ratios and converting from one unit of measurement to another. The Science objectives would include Astronomical measurement units and knowledge about stars related to distance, luminosity and velocity.
My students do not see Mathematics or Science as anything that will ever be of use to them. This will give them an opportunity to see both in the context of events happening in their world today. The success of the Deep Impact Spacecraft in hitting the Tempel 1 Comet is an event that I can use to show my students that there are still exciting challenges out there. You do not have to be an astronaut to be a part of space discovery. Science and Mathematics can be exciting activities that prepare them to be a part of the "final frontier".
Any study of Astronomy in a Physics class would be limited by the time available and the range of topics to be covered. By teaching this in a Mathematics class, students are exposed to the Mathematics and to the Astronomical knowledge in one situation. While I cannot teach to the same level as the Physics teacher, I can build interest and provide opportunities for them to explore on their own. There are many websites available where they can get accurate information at a level that is in their comfort zone.
They will increase their Mathematical skills by using them in a context that is different from what is normally found in the Mathematics classroom. By working with extremely large and extremely small numbers, they will have an opportunity to develop new techniques and confidence. Perhaps the next time a familiar skill is presented in an unfamiliar way, they will be more confident in attempting the work.
