FIVE LABS BEFORE THE FIRST OF THE YEAR (1/2 of your lab grade)--100 points

#1 How different mass stars evolve: Pick 5 different masses of stars and watch them evolve into red giant format. For each, record the mass in terms of of a number _____ mass sun and the time it takes to evolve _______ years. If you graph these, do they form a linear or nonlinear relationship? Turn in your graph and your speculations about what this means for stellar evolution

#2 Types of galaxies: Go to Galaxy Zoo and Register. Take the tutorial, and print out the Congratulations sheet when you are finished. At the bottom of the sheet, please summarize the different types of galaxies that are commonly seen in 1-2 paragraphs, or a picture.

#3 Stellar scavenger hunt: Go to the Sloan Digital Sky Survey(SDSS) to see what's out there! SkyServer brings you the entire public database of the Sloan Digital Sky Survey Digital Photos - almost 150 million stars, galaxies, and quasars - free of charge. We use this data to learn science. Download the sheet and fill in. While you may work with a partner, everyone turns in his/her own data. No two groups should have the exact same answers, as there are so many millions of possibilities. Finding a quasar is worth a bonus +4, but it is not required.

#4 Color: Another SDSS work project, but it's a long one. Again, you may work with a partner. Doing the research challenge at the end would be worth a bonus +20 towards your grade

#5 Asteroids: The basics behind finding those potential killers
