The Making of the Fittest: Natural Selection and Adaptation
The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

Selection and Variation in the Egyptian Origami Bird
Using origami paper birds, your biology class will experiment with mutations and natural selection to determine wing position, length, and width. It would be helpful to provide a worksheet to go with the activity that includes a...

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...

WHAT DARWIN NEVER SAW: Evolution, Science, Biology, Natural Selection
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.

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
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...

Natural Selection Day 1
High schoolers 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...

The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture
Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Beans and Birds: A Natural Selection Simulation
Students solve the following problem concerning the evolution of seed color in pinto bean plants: "How does natural selection change the frequency of genes or traits over many generations?" They use the constructivist approach to...

Human Skin Color: Evidence for Selection
Skin color is controlled by at least six genes. Young scientists learn about skin colors through a documentary. They discuss the topics of pigment, natural selection, and vitamin D absorption. They apply their knowledge to higher order...

A Model for Natural Selection- Spaghetti Worms
Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

Owl Family Natural Selection
How do genetic mutations within a population lead to future variations? Provide your class with the resources to answer this question and more upon completing an activity on natural selection. The entire class participates in a fun role...

A Simple Model for Natural Selection
Do you have what it takes to survive as a fit predator or will elusive prey lead to your extinction? Find out in a creative natural selection activity. Using different colors and shapes of grains to represent different species and...

Natural Selection
Students estimate how many different species of organisms inhabit the Earth. In groups, they match the pictures of embryos at the different stages of development. They compare and contrast animals from the sky, land, and water and...

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...

The Perfect Cow?
Students examine how cattle have evolved through natural selection and selective breeding. In this natural selection instructional activity students compare and contrast natural and artificial selection.

Adaptation and Evolution
Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

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...

Comparing Theories: Lamarck and Darwin
Students compare the evolution theories of Lamarck and Darwin. They use self-assessment and a video to increase their knowledge of evolution theories. They research questions and present them to the class.

The Beaks of the Finches
Students become birds and are given "beak-types". After completing the simulation, students relate results to adaptations and natural selection. Extensions of the simulation allow for comparative results and include population genetics.

The Creation of an Imaginary Species
Students explore the characteristics that distinguish different forms of animal life on Earth which are the results of natural selection and adaptations to their environment. The creatures are created using a game and then drawn by the...

Survival of the Fittest – Battling Beetles
Students explore natural selection. For this genetic adaptation lesson, students discover why certain traits continue and some traits disappear. Students discover how species evolve and change. Resources are provided.

Lamarck And Darwin
Students compare Lamarck's mechanism for evolution with Darwin's theory of natural selection.

Spork and Beans
Students 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.
