A complete study of population ecology is covered by this worksheet. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes worksheet or assigned as homework.

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Students explore the notion of local evolution, or genetic selectivity among different continent-based human populations. They consider specific examples of local evolution, such as lactose tolerance, skin color, and cognitive capacity,...

Explore the practice of oyster gardening. Because oysters play a vital role in marine ecosystems and their populations have declined, biologists are transplanting oyster seed to repopulate reefs. After learning about this practice,...

In this evolution activity students complete a crossword puzzle by answering questions about the environment, evolution and populations. 

Students examine the roles that natural events (such as droughts), population growth and other human factors play on land use and food supply.

After viewing information about different types of isolation, students will see that reproduction among a group will cause the frequency of a specific trait to increase. The history of prominent scientists such as Charles Darwin are and...

How does life evolve? The interactive provides a simulation based on the Game of Life invented by mathematician John Conway. Users can run the applet with the preset rules and settings or adjust them to view whether overpopulation or...

Using this interactive map activity, from A Biography of America, explore how the "New West" evolved during the late 20th century, transforming from the wild, untamed Old Rocky Mountain West into a smaller, more accessible "New West."...

Students investigate plants and compare them to the purple loose strife. As they observe the plants they predict possible impacts on plant populations based on their observations. They work in groups and present their findings to the class.

The Hardy-Weinberg principle is the focus of this concise slideshow.  Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

Octopodes existed for hundreds of thousands of years before humans, yet our eyes share many similarities. Scholars analyze the evidence to determine if the evolution of eyes best fits a homology or analogy model. They discuss the issue...

While cities had only a small fraction of the population in colonial America, they played a significant role in pre-revolutionary years, and this was certainly true for the largest city in the North American colonies: Philadelphia. Your...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

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...

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...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

In this detailed and comprehensive multi-day activity, budding evolutionary biologists use real data from lizard populations in the Canary Islands to examine evolution and natural selection. 

In this evolution worksheet, learners will answer questions about population genetics and the theory of evolution of species. This worksheet has 15 true or false, 6 fill in the blank, and 4 short answer questions.

Can your young biologists interpret population graphs, match macroevolution patterns and descriptions, and answer multiple choice questions about evolution? Find out with a comprehensive three-page quiz covering some specific examples of...

Agriculture, deforestation, and urbanization. How have human's changed the planet and how might we mitigate the effects of human activity on the planet? To answer these questions class members research the changes in human land use from...

We all drink milk as babies, so why can't we all drink it as adults? Examine the trend in lactase production on the world-wide scale as science scholars analyze and interpret data. Groups create pie charts from the data, place them on a...
