Lesson Planet has helped me find many ideas for supplementing the curriculum that is provided to me by my school district. I have found many creative, hands-on activities that make my science curriculum "pop".

In this flower population worksheet, students use a diagram of first and second generations of a flower population to complete 2 short answer questions about genotype and allelic frequency.
Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results. A second set of simulations is performed with natural selection added to the simulation.
Students explain the basics of evolution by natural selection. They calculate allele frequencies as they relate to inheritance. They explain the Hardy-Weinberg Law and how evolution takes place when this law is not in place.
Students investigate how selective forces like food, predation and diseases affect evolution. In this genetics instructional activity, students use red and white beans to simulate the effect of malaria on allele frequencies. They analyze data collected from the experiment and answer analysis questions at the end of the lab.
Here is a cute, yet practical assignment for using the Hardy-Weinberg principle for determining allele frequency in an imaginary family of rabbits. Roger Rabbit, an albino bunny, noticed that some bunnies in his clan had brown fur. Your junior geneticists examine the genotypes for 200 members of the clan and calculate frequency. The worksheet is five pages long and includes an optional interactive extension exercise.
Environmental science stars answer six detailed questions regarding genetic variation and speciation. The worksheet was written for a general ecology course at Sacramento State University and refers to specific textbook pages and class lecture. It can possibly be used for your college ecology or high school AP environmental science course if you preview the questions and make sure they all relate to your curriculum.
The Hardy-Weinberg principle is the focus of this concise slideshow. Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W principle are shown applied to sickle cell and malaria.
The change in genetic makeup of a species over time is explored in this PowerPoint. Facts around parent populations, the Hardy Weinberg principle, and selection under different circumstances contributing to an overall change in genetic make-up are presented.
The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of characteristics of populations.
Research how DNA, the genetic blueprint of living organisms, plays an essential role in the continuity of life. High schoolers will summarize how their influence may very well effect the destiny of the population from one generation to the next. Using interactive learning, group dynamics, and critical thinking learners will use critical thinking to participate in a bean activity to understand the big ideas.
