Population Genetics, Selection, and Evolution
The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Evolution in Action: Data Analysis
An environmental factor, such as a drought, sometimes speeds up the rate of natural selection. Scholars analyze data on the beaks of birds around the time of the drought. They compare those that survived to those that perished and find...

Scavenger Hunt: Simulating Natural Selection
High schoolers simulate natural selection using pinto beans. In this biology lesson, students identify the factors affecting organism evolution. They record data from the experiment and formulate a conclusion.

Artificial Selection
The second lesson in the series begins with a starter activity discussing wild versus domesticated animals. Then, scholars play a card game, with optional variations, to emphasize artificial selection. Next, they attend a field trip to a...

Introduction To Natural Selection
Seventh graders investigate the concept of natural selection and it relation to the theory of evolution. They create a definition for classification based upon looking at other subjects that are similar. The variation of species is...
Curated OER
Natural Selection
Students construct a working definition of the word "evolution," and list the key points of Darwin's theory of natural selection. They create paper moths to help them explain the importance of camouflage and how it relates to natural...

Natural Selection
Pupils comprehend that natural selectionis the tool for adaptation and evolution of populations. They pick three M&M's and no candy corns. Students tally the number of different color M&M's chosen. They discuss why colors were...

The Natural Selection of Stick-Worms
Students discuss and role-play the elements of natural selection. They use toothpicks to represent Stick-Worms and discover the mechanisms of change of traits in populations.

Natural Selection And Evolution
Students investigate the concept of evolution and how natural selection is used as an indicator that evolution has happened. They recognize the three effects it has on diversity and how adaptations can develop. Diversity is explained as...

Natural Selection: Exploring the 'Ohi'a Common Garden
Seventh graders examine natural variation by visiting the Ohi'a Common Garden in Volcano, Hawaii. In this natural selection lesson, 7th graders study background information about phenotypes, genotypes, and phenotypic plasticity before...
Curated OER
Natural Selection
Students use discussion questions, handout information and research topics to explore several issues related to natural selection and evolution. They examine Darwin's research on the finch and antibiotic resistance.

Nowhere to Hide
Students examine the topic of natural selection. As a class, they write their own definition to survival of the fittest and watch a video. Using the internet, they research how Darwin started to examine this process using finches and how...

Adaptations and Evolutions of Species
Examples of natural selection over time will make the concept of evolution more clear to your students. This presentation is short but summarizes the mechanisms of isolation and selection clearly. This presentation would be useful to...

Natural Selection.... a Cumulative Process... it's in the cards!
Learners working in pairs attempt to produce a full sequence of 13 cards of one suit (ace - to king). This must be done by shuffling the suit of cards for each round, then checking the cards.

The Chips Are Down: A Natural Selection Simulation
Students, in teams, use different colored paper chips to represent prey and a piece of fabric as the environment.

AP: Chapter 22: Descent with Modification
After taking in part of Darwin's The Origin of Species, advanced biology learners reiterate its themes and concepts. Also examined are the contributions to the theory of evolution made by Linnaeus, Lamarck, and Wallace. Use this handout...

Genetic Variability
Using black and white construction paper, evolutionary biologists simulate the classic peppered moth study. They use beans in a frequency and natural selection exercise. Finally, they analyze germinated seeds for variations. All three...

Evolution – Diversity of Life
Scientists noticed animals with backbones share similar bone structure despite having different forms, such as fins, arms, and wings. Young scientists gain an appreciation for evolution by understanding the history of the theory. They...

Comparison of Evolution Mechanism
In this comparison of evolution worksheets, students read information about Lamarck's hypothesis of evolution and Darwin's hypothesis of evolution. Students then rate the scenarios given as either supportive of Lamarck's or Darwin's...

Evolution and Adaptations
Survival of the fittest isn't just for the movies! A five-part lesson plan explores several different species with known adaptations and analyzes them for their survival strategies. Using both video and research data, scholars draw...

Stickleback Evolution Virtual Lab
How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

Variations in Living Things
Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

Beaks as Tools: Selective Advantage in Changing Environments
How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

The Making of the Fittest: The Birth and Death of Genes
Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...
