Classify design iteration
Free printable Grade 7 science worksheet for "Classify design iteration" — practice engineering design. No-prep, print or assign online.
Middle school students classify the concept of design iteration — the cycle of testing, evaluating, and improving a prototype — in this challenging Scientific and Engineering Practices worksheet focused on engineering design. Teachers can use it to help students understand that iteration is not failure but a built-in, essential feature of how engineers improve solutions over time. It develops the growth mindset and systematic thinking that underpin effective engineering practice.
Learning objectives
- Define design iteration and classify examples of the testing-and-improvement cycle
- Explain why iteration is a necessary and productive part of the engineering design process
- Apply the concept of iteration to evaluate how a design can be improved after testing
