Description
What It Is:
This worksheet explores how bacteria evolve resistance to antibiotics through mutation and natural selection. It includes vocabulary scaffolding, term matching, and a step-sequencing activity that illustrates the evolutionary cycle of resistance.
Why Use It:
It strengthens understanding of core evolutionary concepts such as mutation, selection pressure, and population change. Students learn how antibiotic resistance develops over time and why evolution acts on populations rather than individuals.
How to Use It:
• Match key evolutionary terms (mutation, selection pressure) to their definitions.
• Number the steps in the correct order to model the resistance cycle.
• Discuss how antibiotics act as a selection pressure in bacterial populations.
• Review the evolution loop together to reinforce population-level thinking.
Grade Suitability:
Best suited for Grades 8–11.
• Middle school advanced life science units.
• High school biology lessons on evolution and microbiology.
Target Users:
Science teachers, homeschool educators, tutors, and students studying evolution, microbiology, and health science fundamentals.
