Adaptations Over Time Substitute Slideshow & Teacher Guide | Life Science | Grades 6–8

This Substitute Slideshow & Teacher Guide gives grades 6–8 Middle School Life Science students a ready-to-run, illustrated lesson on Adaptations Over Time, built around the driving question "How do structural, behavioral, and physiological adaptations evolve over time, and how can mathematical models track shifts in population traits and the formation of new species?"

Slide topics: The Driving Question; Background Information; Structural, Behavioral, & Physiological; Camouflage, Warning Coloration, & Mimicry; Patterns of Trait Selection & Coevolution; Speciation & Adaptive Radiation; Environmental Change vs. Extinction Risk; Trivia Tidbits; The ‘So What?’; Key Takeaways.

What's inside: 11 student-facing slides followed by 12 teacher-guide slides (talking points and demo ideas for each content slide), so a substitute or co-teacher can deliver the lesson.
