Original Prompt

Mimic this lesson. Day 3: The Fair Test (Investigation) Objective: I can conduct a fair test to compare the effectiveness of two flood-reduction models. Instructional Strategy (LER - Feedback): Circulate and ask, "How are you ensuring this test is fair?" (e.g., same amount of water, same angle of the tray). Activity: Testing Day! Groups build their models in a plastic bin with soil. Mathematical Integration: Students measure the amount of water (in mL) that reaches the "protected zone" using

This Teacher Preparation Guide outlines a 45-60 minute activity designed to engage students in the role of flood protection engineers. Participants will set up investigation stations to test flood barrier models using materials such as soil, water, and graduated cylinders. The guide includes preparation steps, learning targets, key vocabulary, and structured activities for building and testing barrier designs. Students will learn about the importance of conducting fair tests, identifying independent and controlled variables, and accurately measuring data. This hands-on activity emphasizes real-world applications and the critical role of engineers in preventing flooding and protecting communities.
