PREVIEW: Today we are going to learn more about variables, which allow us to make BIG changes in our program by changing a single line of code!

• Click Run to see an example of the program you'll be making today.
• Then, find the variable called star_size on line 3.
• Change the value of the variable star_size from 6 to 20. (Don't make it too big, or your screen will freeze!)
• Click Run again to see the changes. When you're finished, click Submit and Next.
