Sample Sections and Exercises in a Darwin’s Natural Selection Worksheet
Vocabulary Building
Match the terms with their correct definitions:
1. Variation
2. Adaptation
3. Fitness
4. Natural Selection
5. Speciation
Definitions:
a. The process where species evolve into new forms.
b. Differences among individuals in a population.
c. The ability of an organism to survive and reproduce.
d. A trait that increases an organism's chances of survival.
e. The mechanism by which advantageous traits become more common.
---
Diagram Labeling Activity
Exercise: Label the following diagram illustrating natural selection:
- Step 1: Variation exists within a population.
- Step 2: Some individuals possess advantageous traits.
- Step 3: These individuals are more likely to survive and reproduce.
- Step 4: The advantageous traits increase in frequency over generations.

Scenario-Based Questions
Scenario:
A population of beetles varies in color—some are green, others are brown. Birds prey more on green beetles because they are more visible on the environment.
Questions:
1. Which beetle color is likely to become more common over time? Why?
2. How does this scenario illustrate natural selection?
3. What role does variation play in this process?
