The Nuclear Fusion Reaction Inside Stars Investigative Science Lab book pages 60-62 What is Nuclear Fusion? Brainstorm: Think/Pair/Share with partner and put your ideas into your lab book. Discuss the following questions (p.60): 1. What is nuclear fusion? 2. Where does nuclear fusion happen? 3. What is produced from nuclear fusion? The Nuclear Fusion Reaction Inside Stars Homework: • Read Nuclear Fusion Article. • Answer Checking In questions on paper. • Due next class. • Keep paper in science folder/binder. How is helium created? With your group discuss how nuclear fusion might happen to create helium. Diagram on dry erase board how helium is made in a star Be ready to present your idea to the class. Let’s draw out all of the element reactions during Stellar Life and Death. Use pages 60-62 in your lab book 1. Let’s draw out the creation of Helium. This happens in the star while it is on the main sequence (p.60) Equation: Protons: Electrons: Neutrons: At. Mass: 2. The creation of carbon is next. This reaction happens in star death. How do you think carbon is created? (p.61) Equation: Protons: Electrons: Neutrons: At. Mass: Homework • • • • Read Supernova Article. Answer Checking In questions on paper. Hand in next class. Keep in science binder/folder. 3. The creation of oxygen is next. This reaction happens in star death. How do you think oxygen is created? (p.61) Equation: Protons: Electrons: Neutrons: At. Mass: 4. The creation of neon is next. This reaction happens during star death. How do you think neon is created? (p.61) Equation: Protons: Electrons: Neutrons: At. Mass: 5. The creation of magnesium is next. This reaction happens during star death. How do you think magnesium is created? (p.62) Equation: Protons: Electrons: Neutrons: At. Mass: 6. The creation of silicon is next. This reaction happens during star death. How do you think silicon is created? (p.62) Equation: Protons: Electrons: Neutrons: At. Mass: 7. The creation of iron is next. This reaction happens during star death. How do you think iron is created? (p.62) Equation: Protons: Electrons: Neutrons: At. Mass: Tracing Our Roots to Space Address the following on page 63 of your lab book 1. What elements would be present in a nebula? 2. What would you expect to happen to elements in a nebula over time? 3. Write a summary of The Fact of the Matter and Nuclear Fusion reactions. 4. How are these two activities related to elements and astronomy?
