Ward's® AP Biology Investigation 2: Evolution: Hardy-Weinberg

Meets AP Science Practices 1, 2, and 5, and Big Idea 1.

• Use mathematical models to determine genotypes and phenotypes in a population

In this lab, students focus on developing a mathematical model for biological populations based on the Hardy-Weinberg equilibrium using a spreadsheet program to record and analyze data. The investigation begins by examining the prevalence of at least one human phenotype within the classroom population and using this as a basis for building the mathematical model. Then, students will use this model to analyze genetic drift and effects of selection in the evolution of populations.

The Only Kits Aligned with AP Science Practices. Ward's AP Biology Investigations provide complete coverage of the Four Big Ideas and Seven Science Practices to help you meet new AP Biology curriculum standards and prepare students for real-world success in college and research-level labs. Each investigation follows a series of three parts, beginning with a structured lab investigation, followed by a related guided inquiry investigation with thoughtful assessment questions, and finally, suggestions to encourage students to formulate their own questions and explore further self-guided experimentation. This complete series of investigations emphasizes the progression to fully student-directed investigations and builds competence in all of the science practices, helping students:
•Practice concept application instead of fact memorization.
•Focus on self-guided experimentation instead of step-by-step lab procedure.
•Investigate real-world concepts with greater curriculum flexibility.
•Apply problem-solving skills to strengthen student inquiry.
