Hardy-Weinberg Equilibrium
Students investigate how Hardy-Weinberg Equilibrium is established and what assumptions and conditions are necessary to reach Equilibrium. They model alleles using materials such as index cards, M & M's and goldfish.
Curated OER
Molecular Approaches to Evolution
High schoolers examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and...
Curated OER
Establishing Hardy-Weinberg Equilibrium
Students study how Hardy-Weinberg Equilibrium was established and what assumptions and conditions are necessary to reach Equilibrium. They record class data on their charts. Frequencies are calculated.
Curated OER
Pre-Hardy-Weinberg
Students examine the inheritance of ABO blood groups. In this investigative lesson plan students perform a lab and show how natural selection can alter the gene frequencies in a population.

Using Molecular and Evolutionary Biology to Understand HIV/AIDS and Treatment
HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...
Curated OER
Natural Selection
Students practice calculating allele and genotype frequencies in the framework of a simple simulation using hard candy, calculators, and a worksheet. This lesson plan includes a three-page worksheet and an assessment question for...

Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...
