The Hardy-Weinberg's principal in hard for students to understand, and use to make predictions about gene frequency, but the concept can be learning without even teaching students the mathematical equation, which is what i did with my 6th grade life science class. We did two different experiments in which we simulating breeding in a population. Students had to predict how their population would change over time, and then collect data from 5-10 generations of breeding to see if their hypothesis was correct. After we finished, I think students understood that populations can change over time, and for different reasons, the environments, the adaptations found within the population, disease, immigration/emigration, etc. Above are some pictures as students keep track of how many alleles were in each generation.
