Partill: Modeling the Sun (20 points) Now it's time to construct your two models. Carry out the plans you described in Part II. Then, write a
report that includes the following: (20 points)
• A description of the processes and/or stages illustrated in each model
• A list of the materials and references you used to design and construct each model
• An explanation of how you can use your models to explain how changes in the proportions of
hydrogen and helium affect the Sun's life cycle
• An evaluation of how well you incorporated evidence into each model
• A suggestion of how you might improve each model
Submit this completed worksheet, your models, and your report to your teacher on or before the due
