 This lesson is functional sun catchers. You'll be creating these pretty sun catchers using functions. There are several steps in creating one of these sun catchers. Some of the steps you have to repeat many times. The first step in simplifying the process of making a sun catcher is to figure out what we have to repeat over and over again. We can group these steps into what we call a function. But there's more to creating a beautiful sun catcher than following precise steps. Sometimes we want to be creative and change the color of the beads we're using. We can make every sun catcher unique if we use different colored beads. Your sun catcher will be uniquely yours when you learn to think of the beads as variables, which is a word that means a placeholder for information that can change. Have fun creating beautiful sun catchers using functions and variables.
