Students investigate how selective forces like food, predation and diseases affect evolution. In this genetics lesson, 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.
High school biology learners simulate gene flow within a population of fish. They hold colored fish cards as identification and carry "Good & Plenty®” candies to represent alleles, the recessive homozygous of which is lethal. You will need to construct the fish cards and set obstacles up around the room for fish to swim around. 
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.
High schoolers 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.
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.
Students 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 assess historical continuity among closely and distantly related species. Students research and work on molecular data.
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.
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.
Students determine the types of natural selection and variation that exists in a population, using beans.
Students discuss Darwin's theory of evolution. In this biology lesson, students investigate what influenced Darwin's thinking as it relates to Evolution. They discuss pros and cons of Natural Selection.
In this evolution learning exercise, students review the genetic aspect of evolution such as gene pools, specific traits, and genetic mutations. This learning exercise has 15 multiple choice and 5 fill in the blank questions.
In this evolution worksheet, learners look at the role genes play in the transferring of traits to generations. Students review gene pools, natural selection, and genetic drift. This worksheet has 5 fill in the blank and 15 multiple choice questions.
For advanced biology learners, here an interesting presentation on Alu elements within a population. It begins by teaching viewers how to perform calculations for alellic and genotypic frequencies. The second half of the slide show walks them through the use of an online allele server. With this tool, they discover whether on not the class is consistent with Hardy-Weinberg equilibrium. 
Well, shiver me timbers! Biology pupils practice using the Hardy-Weinberg principle for computing change in gene frequency within a fictional population of pirates. The genetic trait being analyzed is the presence of sea legs, legs that prevent them from falling over when the ship is tossing. A combination of math and science makes this a handsome treasure to increase the value of your genetics unit!
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all the difference in survival when the landscape changes drastically. After watching the video, high schoolers take a look at the Hardy-Weinberg theorem, perform some calculations regarding the frequency of heterozygous genotypes in the rock pocket mouse population, and answer some short analysis questions. 
Again, the basis for trait inheritance and the impact of alleles in phenotypes was covered in previous videos. This presentation focuses on gender and the likelihood of traits if they are sex-linked. Sal tells a great anecdote about where the blame should have been placed for Henry VIII's female offspring.
This instructional activity will help students examine their preconceptions and assumptions about racial categories and understand the impossibility of constructing a consistent system of human racial classification.
Learners examine natural selection, how it works and how it can cause microevolution.  In this evolution lesson students complete a lab activity that shows the effects that natural selection has on organisms.
Students explore natural selection. In this genetic adaptation lesson, students discover why certain traits continue and some traits disappear. Students discover how species evolve and change. Resources are provided.
