Name______________________ Per_______ Date_____________________ Life Cycle of Stars Lab Part 1 1. Look at the nine pictures of people at various ages. Classify these pictures in order from youngest (1) to oldest (9). As you do this, pay attention to the method you use to figure it out. Try to determine the ages of the people pictured. A)______age:____ B)_____age:_____ C)______age:____ D)______age:____ E)_____age:______ F)______age:____ G)______age:____ H)_____age:_____ I)______age:_____ 2. Write a DETAILED description of the method you used in the activity above. What traits and characteristics did you use, and what clues from one picture helped you with another? Describe your method in enough detail that other students could follow it and get the same answers you did. 3. Check how you did against the answer key. Describe any mistakes you made, and why you think you made them. Part 2 – on computer 4. Read the background on star formation found on the link from Mr. Mason’s website (http://btc.montana.edu/ceres/html/LifeCycle/starsbackground.htm) 5. Number the following life stages in the order that they occur. Number the medium and large stars separately. Medium Stars (sun) Large Stars__________________ ______White Dwarf _______Neutron Star or Black hole ______Main Sequence Star _______ a large cloud of interstellar gas and dust ______Planetary nebula _______ Supernova ______Red Giant _______Main Sequence Star _______ proto-star (embryonic) ______a large cloud of inter_______ Supernova Remnant stellar gas and dust _____ proto-star (embryonic) 6. What conditions or events lead to the formation of a black hole? 7. You will now see a slide show of images located at: http://btc.montana.edu/ceres/html/LifeCycle/starsunbigstar.html This page shows eight NASA images from the Hubble Space Telescope (HST). These are pictures of the formation sequence of really BIG stars. Your FIRST task is to figure out and record the correct sequence of pictures from birth formation to stellar death. You must also list the stage that the star is in. Pay careful attention to how you determine the sequence because your SECOND task is to write a detailed description so clear that other students will understand it, and be able to use it as a model to come up with the same sequence. Each picture is hyperlinked to a description of the picture for background information IF you need it.

Write a DETAILED description of the method you used in the activity above. What traits and characteristics did you use, and what clues from one picture helped you with another? Describe your method in enough detail that other students could follow it and get the same answers you did.
