    No More Chores! Engineering Challenge

    No More Chores! Engineering Challenge

    Overview

    Learners will design a combined machine to eliminate one chore they may dislike. Once learners work through the engineering design process, they will share their prototype locally.

    Driving Question / ScenarioMany children complain about doing chores at home. Learners will think like an engineer and create an invention (a combined machine) to eliminate one chore for themselves. Learners will follow and complete the engineer design process and create a prototype.
    Project SummaryLearners will design a combined machine to eliminate one chore they may dislike. Once learners work through the engineering design process, they will share their prototype locally.

    Educational Standards7.P.2 Understand forms of energy, energy transfer and transformation and conservation in mechanical systems
    Classifying Objective7.P.2.4 Explain how simple machines such as inclined planes, pulleys, levers and wheel and axels are used to create mechanicaladvantage and increase efficiency.
    EngageThe teacher will select 1-2 suggested engage activities from the Teacher Resource document.
    Project Outline
    AskComplete the Ask on the Student EDP Planning Sheet (5 minutes)Constraint: The invention must be a compound machine. A compound machine consists of two or more simple machines put together. In fact, most machines are compound machines. Some examples are a pair of scissors and a bicycle.
    ImagineComplete the Imagine on the Student EDP Planning SheetBrainstorm (2 minutes).Sketch 2 Designs for your chore elimination invention. (5-10 minutes)
    PlanComplete the Plan on the Student EDP Planning Sheet (5 minutes)
    CreateBuild the chore elimination invention. (20-30 minutes).Complete the Create on the Student EDP Planning Sheet (5 minutes)
    ImproveStudents test their chore elimination invention.Complete the Improve on the Student EDP Planning Sheet (5 minutes)If time permits, students brainstorm revision and rebuild their chore elimination invention.
    ShareComplete the Share on the Student EDP Planning Sheet (5 minutes)
    Closure / Student ReflectionsStudents reflect individually and then share out. (10 minutes)
    • Explain your solution and why you designed it the way you did.
    • Share how you used the Engineering Design Process.
    • How do you plan to ask for feedback on the invention and answer questions others have about your solution.
    Possible Modifications / ExtensionsThis lesson can be done as an individual or team.Showcase day-Learners display their prototypes at school or via flipgrid.Learners make an advertising brochure to “sell” your machine. Include a labeled drawing—and be sure to explain how it works.
