“This Friday we'll have the yearly Egg Drop Challenge,” said our science teacher, Mr. Baker. “You can work alone or with a partner.”
My friend, Cassie, and I smiled at each other. We always worked on projects 36 .
The 37 of the challenge was simple—to build a protective container to keep an egg from breaking when 38 the stadium wall.
