Here are some ways to help students reflect on the lesson.
Feel free to copy and paste them into an assignment.

1. How is glass made?

2. What did this lesson make you curious about? What other questions do you have about glass?

Bonus Activity: Go on a glass “scavenger hunt” in your home. You likely have windows made of glass, but what else? How many different glass objects can you find? How do you know that they’re all glass? Write or draw at least three things you notice that all of these objects have in common. Write or draw at least three things that are different about the objects.
