The Effect of Natural Selection on Genes, Traits and Individuals
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...

Genetic Variation Worksheet
Fill- in-the-blank, labeling, and short answer questions make up this well-written cell division worksheet. Neat diagrams of chromosomes and dividing cells are included. Junior biologists show what they know about reproduction, meiosis,...
Curated OER
Form and Observation
Use a familiar song and adorable baby animal pictures to teach youngsters about genetic variation. Begin by listening to "Twelve Variations on 'Ah vous dirai-je Maman,'" which you will need to find online (there are several versions...

AP: Chapter 23: The Evolution of Populations
How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and selection.
Curated OER
Adaptations to Niches and Habitats
Life science learners measure and record traits of seeds, leaves, and their own hands and then graph the data to find a continous distribution curve. They compare and color diagrams of seven different animals' forelimbs (not included),...
Curated OER
Gene Switches- A Model
Students explore genetic variation within a population. In this genetic adaptation lesson, students investigate the reasons contributing to genetic adaptation. Students collaborate and analyze DNA models. Multiple resources are provided.
Curated OER
How Evolution Works
Students work in groups to investigate and present genetic variation, adaptation, and sexual selection as it relates to evolution. In this evolution lesson, students watch a video discuss how the human eye could evolve due to natural...

Clipbirds
Learners attempt to pick up various objects with a wide variety of beaks, including scissors, spoons, etc.

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
The Acetate Animal Hunt
High schoolers determine which adaptations allow an organism to survive and reproduce in a certain environment. Students act as "predators" to pick up acetate discs "prey" scattered around the classroom. High schoolers list the number...
Curated OER
Battle of the Beaks
Students explore adaptive advantage, based on beak function, by simulating birds competing for various foods.
Curated OER
Genetic Variation
Young scholars study families and their genetics. In this investigative lesson students explain how variations in genetics can be harmful and how some can help with survival.
Curated OER
Reproduction and Development
In this development worksheet, students compare the characteristics of mitosis and meiosis. Students review the male and female reproductive organs and their functions. This worksheet has 4 graphic organizer, 6 short answer, and 16 fill...
Curated OER
Natural Selection
Students observe, measure and record variations that may be due to genetic inheritance. They look at the length of seeds for germinating pinto and lima beans and measure the distance between eyes in humans. They graph and discuss the...
Curated OER
Natural Selection in Protected And Unprotected Populations
Studnets compare how two elephant seal populations fare during successive generations. They participate in a simulation using a card game to look at the differences in two populations, one that is protected from mortality by human...
Curated OER
Of Mice and Moths
Students study the concept that genetic variation of offspring contributes to population control. They create a presentation showing natural selection and survival of the fittest.
