Hit the green flag and wait for the program to start.
In Science class we learned about the mechanics of catapults and then designed and built our own. In Computer Science class we were challenged to solve the design problem: How might we design a computer model that informs a user about the mechanics of how a catapult works? I used Design Thinking to create a Scratch program that is a solution to the user need: A person that knows nothing about the catapults needs to know how to build a basic catapult so as to making one that is great and work.
