Name________________________________ Period____ Date_________ Star Life Cycle Page 1: Star Life Cycle, What’s out in Space? How is a star’s life cycle like a human’s life cycle? What is a nebula? Why are they important to a star’s life cycle? Page 2: Protostars and the Nebula Watch the animation of how a star begins to form out of a nebula. What is a protostar? What causes the dust and gas to together and eventually turn into a protostar? What nuclear process occurs that marks the official of the star? “birth” Page 3: Stars What is a star? Stars spend most of their lives as a main sequence star. What is a main sequence star? Complete the interactive lab. Click through the animations for each possible starting mass of a star. How does the starting mass of a star affect how long it is on the main sequence? (In other words, does a more massive star have a longer or shorter life on the main sequence?) Page 4: Stars, Equilibrium, Hydrogen burning (fusion) What is equilibrium and why does a star want to reach equilibrium? Read through the rest of the info on this page. Test your knowledge with the Star Quiz (part 1) at the bottom of the page. Page 5: Stars: The beginning of the end Read through the info on this page. Test your knowledge with the Star Quiz (part 2). What happens after the hydrogen burns out and the star begins to burn helium? What is the next stage of a star after main sequence?
