Product Description
This activity asks students to explore what happens to allele frequency in a population of goldfish when environmental pressures (the introduction of a predatory octopus!) are placed on them. Students will be asked to make predictions, interpret data and allele frequencies, create a graph of the allele distribution, and (most importantly) eat goldfish.

I have uploaded this in a .docx format so you can modify and differentiate for your classroom and students' needs. I recommend going through the first "generation" with the class to save confusion and questions. Enjoy!
