Station Rotation: Engineering Design Challenges for Grade 7
A multi-station engineering assignment for 7th graders that reviews STEM concepts through the MS-ETS1-1 standard, using a Millbrook bridge scenario to practice defining criteria and constraints for a design problem. Students work through stations with key-term callouts, a guided scenario, and written response prompts, making it well suited to a 45 to 60 minute rotation block or small-group work.
Teacher Guide & Tips
- Use this as a rotating station activity during an engineering design unit, having small groups move through each station and record answers on their individual worksheets before a whole-class debrief.
- Discussion question: How is a criterion different from a constraint, and which one would the Millbrook engineers need to satisfy first if the budget was very limited?
- Scaffold for struggling readers: Pre-teach the terms "criteria" and "constraints" with a simple anchor chart, and have students circle key words in the Millbrook scenario before writing their responses.
- Extension for advanced students: Ask them to draft a short list of three criteria and three constraints for a bridge that must also accommodate flood conditions, and justify their priorities in a brief paragraph.
- Estimated time: About 10 minutes per station, or roughly 45 to 60 minutes total for a full rotation with a short debrief.
