======Frog Natural Selection Simulation====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Frog Population and Predation Model, Natural Selection Frog Model ====Summary==== {{$demo.summary}} ====Procedure==== - Use frog cards and a dice, and follow the instructions in the links to model natural selection in a frog population. ====Links==== 📄 Natural Selection Investigation - Mr Fraser: [[https://petergef.weebly.com/natural-selection-investigation.html]]\\ 📄 Natural Selection Frog Selection Activity - Studocu: [[https://www.studocu.com/en-au/document/wavell-state-high-school/biology/natural-selection-frog-selection-activity/101846664]]\\ ====Variations==== * Change predator numbers (e.g., 10 or 20 frogs eaten each year) to see effects on survival. * Introduce an environmental change (e.g., pond vegetation colour shift) and track changes in which frog color is favoured. * Allow students to design their own predator–prey rules to model different ecosystems. * Attempt to program a computer to model the simulation. ====Safety Precautions==== None ====Questions to Consider==== * Why are red frogs most likely eaten in the pond and yellow frogs in the forest? * How did the frog populations change over time in each environment? * How does this classroom model differ from real frog populations in nature? * What role does natural variation play in the survival of species? * How might environmental changes affect which frogs are most successful? * What conclusions can be drawn about natural selection from this model?
