Engineering Design Process

The engineering design process is a series of steps that guides engineering teams as we solve problems. The design process is iterative, meaning that we repeat the steps as many times as needed, making improvements along the way as we learn from failure and uncover new design possibilities to arrive at great solutions.

Overarching themes of the engineering design process are teamwork and design. Strengthen your students’ understanding of open-ended design as you encourage them to work together to brainstorm new ideas, apply science and math concepts, test prototypes and analyze data—and aim for creativity and practicality in their solutions. Project-based learning engages learners of all ages—and fosters STEM literacy.

Engineers ask critical questions about what they want to create, whether it be a skyscraper, amusement park ride, bicycle or smartphone. These questions include: What is the problem to solve? What do we want to design? Who is it for? What do we want to accomplish? What are the project requirements? What are the limitations? What is our goal?

This includes talking to people from many different backgrounds and specialties to assist with researching what products or solutions already exist, or what technologies might be adaptable to your needs.

You work with a team to brainstorm ideas and develop as many solutions as possible. This is the time to encourage wild ideas and defer judgment! Build on the ideas of others! Stay focused on topic, and have one conversation at a time! Remember: good design is all about teamwork! Help students understand the brainstorming guidelines by using the TE handout and two sizes of classroom posters.

For many teams this is the hardest step! Revisit the needs, constraints and research from the earlier steps, compare your best ideas, select one solution and make a plan to move forward with it.

Building a prototype makes your ideas real! These early versions of the design solution help your team verify whether the design meets the original challenge objectives. Push yourself for creativity, imagination and excellence in design.

Does it work? Does it solve the need? Communicate the results and get feedback. Analyze and talk about what works, what doesn't and what could be improved.

Discuss how you could improve your solution. Make revisions. Draw new designs. Iterate your design to make your product the best it can be.
And now, REPEAT!

  • Be “Cool” with Popsicle Engineering
    Be “Cool” with Popsicle Engineering

    Students follow five steps of the engineering design process and make a popsicle production line that the class can enjoy. Beginning kindergarteners are introduced to science and engineering concepts and compare and contrast the roles of a scientist and an engineer.

  • Invent a Backscratcher from Everyday Materials
    Invent a Backscratcher from Everyday Materials

    In this activity, students create devices to get "that pesky itch in the center of your back." Once the idea is thought through, students produce design schematics (sketches).

  • Naturally Organized
    Naturally Organized

    Students learn about biomimicry and the engineering design process by designing a tabletop supply organizer inspired by the natural home of an insect species. Their prototype stores the group’s classroom supplies, such as scissors, crayon boxes, pencils, and glue sticks. They must design their suppl...

  • Straw Towers to the Moon
    Straw Towers to the Moon

    Students learn about civil engineers and work through each step of the engineering design process in two mini-activities that prepare them for a culminating challenge to design and build the tallest straw tower possible, given limited time and resources. In the culminating challenge (tallest straw t...

  • Engineering a Mountain Rescue Litter
    Engineering a Mountain Rescue Litter

    Students build small-sized prototypes of mountain rescue litters—rescue baskets for use in hard-to-get-to places, such as mountainous terrain—to evacuate an injured person (modeled by a potato) from the backcountry. Groups design their litters within constraints: they must be stable, lightweight, lo...

  • Biodomes Engineering Design Project: Lessons 2-6
    Biodomes Engineering Design Project: Lessons 2-6

    In this multi-day activity, students explore environments, ecosystems, energy flow and organism interactions by creating a scale model biodome, following the steps of the engineering design process.

  • Exploring Variables While Testing & Improving Mint-Mobiles
    Exploring Variables While Testing & Improving Mint-Mobiles

    Students design, build and test model race cars made from simple materials—lifesaver-shaped candies, plastic drinking straws, Popsicle sticks, index cards, tape—as a way to explore independent, dependent and control variables.

  • Water Bottle Rockets
    Water Bottle Rockets

    Students are challenged to design and build rockets from two-liter plastic soda bottles that travel as far and straight as possible or stay aloft as long as possible. Guided by the steps of the engineering design process, students first watch a video that shows rocket launch failures and then partic...

  • Saving a Life: Heart Valve Replacement
    Saving a Life: Heart Valve Replacement

    Students use their knowledge about how healthy heart valves function to design, construct and implant prototype replacement mitral valves for hypothetical patients' hearts. Building on what they learned in the associated lesson about artificial heart valves, combined with the testing and scoring of ...

  • Clay Boats
    Clay Boats

    Students use a small quantity of modeling clay to make boats that float in a tub of water. The object is to build boats that hold as much weight as possible without sinking. In the process of designing and testing their prototype creations, students discover some of the basic principles of boat desi...
