On Saturday we learned how to purify the water samples obtained the previous day in the Snowy Range. We also learned more about the electromagnetic spectrum and how to combine astronomical images taken at different wavelengths to create a nice multi-color picture (ask the campers to show you theirs). After lunch we explored a bit of statistical analysis of numerical data, and then did some practice for our camping trip on Mt. Jelm (setting up tents, tying ropes, first aid, etc). The rest of the day was on the mountain, roasting hot dogs, telling ghost stories, singing campfire songs, doing silly skits and dances, and using our largest telescope to take spectra of their stars. These spectra will be used later in the computer lab to characterize the physical properties of the stars and to help assess if they could possibly harbor planets that could be habitable.
