=How Stars Change Over Time - Composed by the Students of Oxford Hills Comprehensive High School's Freshman Team 2= media type="custom" key="2696603"

We used the following methods to create our graph.

We found the absolute magnitude and the color, then used the inverse square law and stellar parallax to make the H-R Diagram.

We noticed the following patterns while looking at the graph. Pattern 1 is between -10 and 8 magnitude and has a strong negative correlation, we can see that because the stars are all overlapping and tightly packed together. These stars are affected mostly by fusion, because of their large size. Pattern 2 has a magnitude between -8 and 4 and also has a strong negative correlation. This we can see because the stars aren't quite so overlapping, but they are still tightly packed. Pattern 3 has a magnitude between 10 and 18, and has a weak negative correlation. This is clear because all the stars are scattered far away from each other.

Based on the patterns we see on the graph we draw these conclusions.
