1. Iteration, collaboration, and documentation

    Iteration, collaboration, and documentation

    Iteration, collaboration, and documentation are integral parts of engineering design. This challenge is intended to provide students with an opportunity to develop their understanding and appreciation of these important ideas. To run this activity, first divide the class into at least three different groups. Stage 1 Challenge each group to...

  2. Energy losses

    Energy losses

    One of the most important topics of engineering and design is losses. In many classes, we ignore losses (such as friction) to simplify problems while learning the physics of engineering. But when we solve real life engineering problems, we need to be aware that losses are always present and are a...

  3. Iteration and efficiency

    Iteration and efficiency

    Efficiency is important in engineering, not only in materials but also time, money and energy. It is important for a young engineer to learn the value of an efficient product. Anyone can build a bridge with as many pieces they desire, but can you do it with fewer and fewer?...

  7. Learning sequence: Learn about gears

    Learning sequence: Learn about gears

    This suggested sequence of activities begins with an exploration of simple hand-powered gear trains. The second and third activities use gears to decrease the rotational speed of motor-powered music boxes and fans. The last three activities incorporate gears into cars so that they can win a “snail race” or climb...
