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

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?
