Engineering Design Process: Simple Machines
Time Frame: # 3-4 weeks
Overview of Unit

Overview of Unit |
|
In this activity, students will learn about and apply the Engineering Design Process to solve a problem. While working through the steps of the Engineering Design process they will focus on defining the criteria and constraints of a design problem, learn about scientific principles of simple machines, understand tool and machine safety, and create a prototype solution to the problem. The activity frames the problem around researching, designing, building and testing a prototype that is built with at least one simple machine that will launch a ball into a target. At end of unit students test their prototypes and present their findings of working through the process. Resources included in this lesson are found at the bottom of this document and include: ● Teacher day by day rough guide ● Engineering Design Process Presentation ● Engineering Journal for students to use with activities, notes, and study guide ● Links to unit resource videos/websites for games, quizzes, TED talks, and visuals ● Unit Test ● Project Rubric |
