In this lab, students will model natural selection by simulating a population of bunnies that have variation in their fur. They will be challenged to understand what happens to both desirable and undesirable genes over time, how the environment can affect populations, and how natural and artificial selection affect a population.
Students should have a basic understanding of traits, dominant and recessive genes, and Punnett squares. It is important to note that this activity does not represent exactly what would occur with a population of real bunnies, but rather simulates the change in allele frequency over time.
The product contains three complete labs that are differentiated for all of your students.

3 Differentiated Labs
Dependent Student Lab- A complete lab. This level is written with a combination of procedural instructions and inquiry questions. They are moderately student-centered with guided inquiry questions throughout the lab. Suggested for on-level learners.
Modified Student Lab - A complete lab. This level provides the most structured lab experience. The lessons may eliminate parts of the lab and change the questioning to include sentence stems or multiple choice questions. Suggested for learners with modifications.
Independent Student Lab - A complete lab. This level is the most student-centered experience. Suggestions are made for the students to get started, but most of the decisions will be student-centered. The students will be responsible for most aspects of the lab and will have the least guidance. Suggested for advanced learners.
Materials Needed Per Group:
50 dry brown beans (can be purchased in a grocery store)
50 dry white beans (can be purchased in a grocery store)
breeding placemat – can be laminated for reusability (included)
2 plastic cups, one labeled “Breeding Grounds” and one labeled “Graveyard"
TEKS: 7.11C - Identify some changes in genetic traits that have occurred over several generations through natural selection and selective breeding such as the Galapagos Medium Ground Finch (Geospiza fortis) or domestic animals.
NGSS: MS LS1-5 - Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
NGSS: MS LS4-6 - Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.
