**In this activity you will sequence the stages of a star's life. Use the links below to complete the activity.
 * The Lives of Stars


 *  You may review the stages of a star's life here

Activity 1: Investigating the Human Life Cycle ** Activity Page One ([|unsequenced human life cycle page]) shows eight pictures of humans at various ages. Your FIRST task is to figure out and record the correct sequence of pictures from youngest to oldest. 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. This might not be as easy as it appears. THIRD, check your sequence with the expert sequence ([|sequenced human life cycle page]) and propose explanations for any discrepencies.

Activity Page Two ([|unsequenced large star cycle 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. 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. THIRD, check your sequence with the expert sequence ([|sequenced large star cycle page]) and propose reasons for any discrepencies. FOURTH, and most important, write a paragraph or two that describes the sequence of stellar formation, life cycle, and death. Use sketches or pictures from the WWW to support your description.
