The Making of the Fittest: Natural Selection in Humans
Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

Artificially Selecting Dogs
Selective breeding has resulted in some novel and beautiful or useful dogs over the years. Using the American Foxhound as an example, genetics learners find out how and why they came about. Then, in small groups, they select breeds 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...

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 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...

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,...

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...

Evolution of Fur Color in Mice – Mutation, Environment and Natural Selection
Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

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...

Introduction to Natural Selection
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...

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.

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...

Evidence of Evolution
What an impression fossils make! In this activity, aspiring paleontologists view fossils and construct a timeline to further understand how the lack of natural adaptation caused historical organisms to become extinct. While they should...

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...

Biodiversity and Evolution – Darwin’s Finches
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 food...

Natural Selection- the Peppered Moth
Can human activity cause animals to evolve? Your budding biologists will find out the answer to some of the big questions in natural selection with a peppered moth activity. They will watch a few short videos, look at pictures, and...

Human Evolution
As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

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...

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...

Natural Selection
Kids act as scientists and preditors in this short natural selection activity; they collect and analyze data, then apply their new knowledge to real-world examples of natural selection. The layout of the worksheet is easy enough to use...

How Does Evolution Work?
Students investigate how natural selection influences evolution. They complete a hands-on lab simulation of natural selection, and replicate a real experiment and examine the interplay between selection factors in a population of guppies.

Why Does Evolution Matter Now?
Students examine how natural selection creates antibiotic-resistant bacteria,
recognize applications of evolutionary principles for medicine, agriculture, and conservation, and discuss how science contributes to decisions in context of...
