This activity allows students to demonstrate their understanding of the concept of natural selection. Students are asked to choose any single organism and any single variation within their population. Instructions provide suggestions and questions to get students thinking about each of the four components of natural selection:
1. Variation among individuals within a population
2. Competition for resources
3. Selection for individuals with advantageous traits
4. Reproduction (new population reflects the advantageous traits that are passed down.
This activity provides a space for a rough draft, but I have students transfer their final model to a poster board. Encourage students to be creative - one of the best models I have ever received was of selection in Pokemon!
I have uploaded this in both a .docx and a PDF format, so you can feel free to use "as is" or modify and differentiate to meet your classroom and students' needs. Enjoy!
HS-LS4-2. Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
