| Abstract: |
Spectroscopy is arguably the most valuable tool professionals use to study the stars. So it's disappointing that as educators we haven't had effective tools with which to teach it. Handheld plastic spectrometers, meter sticks, and diffraction foil all often end up frustrating both us and our students. In this three minute video, we'll show you an inexpensive live video spectrometer: RSpec Explorer. You'll see how enormously effective a live video feed combined with an LED array and gas tubes can be. You'll hear from teachers like yourself who (along with their students) now love the science of spectroscopy. You'll also see how you can use a small telescope (or even a DSLR), an inexpensive diffraction grating, and the same live video to capture the spectra of stars. Combining gas tube and astronomical spectra is the key to student understanding. We'll also show you a Periodic Table of Spectra poster that will help you teach spectroscopy. Your presenter in this video is Tom Field, who has been a Contributing Editor at Sky & Telescope Magazine for more than ten years. Tom is also the founder of Field Tested Systems. |
