🎣 Vanishing Brook Trout Launch
Critical Thinking & Problem Solving
8.MS-LS4-4
Real-World Challenge
Submission Required
Students analyze a short case study with photos, a temperature graph of a local river, and a brief quote from a fishing cooperative member about declining brook trout catches. The teacher facilitates a mini-lesson connecting environmental change, genetic variation, and survival across generations. Students generate initial noticings and wonderings about how traits like temperature tolerance or body size could influence survival.

Preparation (3 items)
- Prepare and print case study materials, including photos and the temperature graph.
- Establish connection with a local fishing cooperative to gather quotes and data.
- Set up the workspace with all necessary materials and arrange seating for group discussions.
Student-facing instructions
You will explore how environmental changes impact brook trout populations. Analyze a case study using provided photos, temperature graphs, and expert quotes. After reviewing the mini-lesson, generate observations about how genetic traits like temperature tolerance influence survival. Collaborate with peers to discuss and list questions about trout traits and survival factors for further investigation.
