You are an engineer who specializes in designing cool toys. You are recently contacted by us, Mochy Kid Limited, to help design a machine called a catapult (彈射器) that will launch balls at a series of targets.
The engineering design process involves a loop of design, build, test, evaluate and redesign a product or structure through many iterations, so as to find out the best design. Engineers follow such engineering design process, whether in designing a Tesla car powered by battery, a rocket to take us to the moon, an artificial leg for a runner, or the hottest toy for kids.
To ensure that players will love the game, you need to test your catapult and record your findings onto the workbook.
