Unit 6.6: Lesson 5
How does an injured foot help students understand nervous-system communication? Follow this two-day lesson through visual models, a movement game, six condition stations, and a discussion of healing and accessibility. Includes four optional reaction-time lab versions.
Unit 6.6: Lesson 2
An arm model, an injury simulation, and three days of notebook work helped students explore how subsystems work together—and what happens when one is damaged. Here’s what worked, why the spring-scale measurements fell short, and why I’m bringing back the frog-leg dissection.
