Purpose: In this assignment you will demonstrate what you understand about the life cycle of stars and how
elements are formed.
Directions: Complete the parts below.
PART 1:
According to NASA, “nucleosynthesis” means “the creation of new elements in stars by combining lighter nuclei to
make heavier nuclei.”
Write a definition of nucleosynthesis you could use with an elementary school student.
Lighter nuclei come together to make heavier nuclei, and when that happens, it creates a new element
Draw a model on paper of how you think this happens in stars, take a photo of it and insert the picture in the
space below.
Diagrams from the internet at not acceptable.
In words, describe why you have drawn the model the way you did. Include terms from your model where you can.
I have drawn this model the way I did because it shows how the nuclei come together
List three questions you have that will help you understand the question of where natural elements of the universe
originate.
1 What happened after the explosion happened?
2 How are new stars able to form?

3 How do they study stars and know where they are?
Use this website to answer the questions you wrote in the spaces below. http://aspire.cosmicray.org/Labs/StarLife/
1 After the explosion occured it created the basic air elements
2 In order to get other elements, they must be built out of hydrogen through nuclear fusion, which occurs
within stars.
3 The HR Diagram
From Earth, there are a number of things that we can observe about stars. One of the easiest things to
measure is the star's brightness, or magnitude.
PART 2:
Using the same website from Part 1, start with the section on Protostars, then the section on Main Sequence. Notice that
there is a good glossary available to you
