A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

This editable instructional activity is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction....

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Students develop an understanding of natural selection, specifically, how it unfolds from generation to generation. They work in small groups to perform an experiment using beans. They use a worksheet imbedded in this plan to guide their...

Can natural disasters alter natural selection? The interactive explores this concept with mice living through a forest fire. As the environment changes, the camouflage also changes. How does this one disaster impact future generations?

Students define the concept of classification. In groups, they categorize a series of objects into categories they identify. As a class, they participate in a variety of activities to examine the concept of natural selection. To end...

Students view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.

Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could...

Can human activity influence the colors of moths? The simulation explains how pollution changed the color of tree bark, which led to the survival of a different variation of moths. It also discusses the shift back as air quality improves.

Do predators look for different things in different seasons? The quick interactive shows how some species survive longer in one season than another based on the conditions. The challenge questions encourage pupils to demonstrate that...

Although the instructions include reading from a specific textbook, the tasks are appropriate for any unit dealing with how genotype frequency changes over time. Junior biologists define five vocabulary terms and then answer five...

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...

Students participate in a discussion about the three types of natural selection. In groups, they identify examples of adaptations from photographs. To end the lesson, they analyze results of natural selection in adaptation, behaviors...

Learners 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...

Students investigate natural selection and differential survival among divergent phenotypes of a population. Using everyday items , they model adaptations of camouflage and protective coloration in two very different environments.They...

Pupils 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.

In this ecosystem worksheet, students answer questions about energy pyramids, food chains, consumers, producers, decomposers, biotic and abiotic factors in an environment, natural selection and the importance of biodiversity in an...

Students examine adaptation through a hands-on activity and determine how the gene pool can affect adaptability. They simulate a predator and prey relationship by going on a hunt for colored acetate disks. After a three minute hunt, they...

Thirty short-answer questions comprise this detailed review of evolution theory. Many of the questions ask scholars to define vocabulary. Because short answers are required, this worksheet will take some time to complete. You could give...

Class pairs select a prompt from a provided list and tell (and record) their story to their partner. They then examine linguist William Labov's model for natural narratives, and apply his model to their tale. Next, class members watch...

Teens experience natural selection firsthand (or first beak) in an activity that has them act as finches foraging for food. Using different household items  to act as different beak styles, your little finches will collect as much...

Students simulate the changes in a natural population of birds or other species. They establish baseline data of population fluctuation for a closed population with a stable food supply. They graph the data to complete their mutations.

Learners pretend they are a scientist like John Endler in this Web activity. They visit his pools, from hypotheses, and test them out. In the process, the explore about natural selection and sexual selection. They are able to explain the...

Students illustrate the results of natural selection by identifying conditions that could lead to the development of new species (speciation) based on a given description of environmental conditions and description of variation within a...
