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...

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...

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...

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.

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?

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....

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...

Adaptation or acclimation? Young ecologists determine which is being exemplified in twenty questions. When teaching about adaptations, make sure to talk about acclimation, a short-term learned response to a change in the surroundings....

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...

Pretend you are exploring a newly discovered species of fish in the Galapagos. Your budding marine biologists access FishBase Database's list of marine/brackish fishes and choose one to research. The link through this website does not...

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...

In this relationships and biodiversity instructional activity, high schoolers investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and...

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 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...

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...

Students practice identifying different groups of living organisms using a dichotomous key. Students also examine the history of an organism and its lineage by writing a paragraph about it and "three generations" of ancestors.

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...

Students examine various inheritance patterns using pedigrees. In groups, they predict what might happen to the offspring of a woman with normal vision and carries the recessive allele gene. They determine the genotypes of the man and...

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 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...

Students identify and illustrate how changes in DNA cause mutations and evaluate the significance of these changes. They illustrate a chromosomal mutation such as duplication, deletion, inversion, and translocation.

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...
