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...

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...

Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

Survival of the fittest isn't just for the movies! A five-part lesson explores several different species with known adaptations and analyzes them for their survival strategies. Using both video and research data, scholars draw...

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...

Whether or not you think mice are nice, you'll love the colorful activity! Scholars examine evidence for evolution in the rock pocket mouse through video, discussion, and collaborative work. Learners watch a video regarding variation in...

Students participate in a variety of activities to introduce them to biology. In this biology lesson plan, students use microscopes, discover bacteria, view human anatomy, and more.

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's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...

Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

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...

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...

Is there one right way to control infectious diseases? Learners determine the facts each stakeholder must consider when making their recommendations for controlling a disease threatening their area. They take into account public health,...

This is a lesson designed by a biology teacher. In it, students use maps and evidence of island age, molecular genetics, morphology, and distance apart to determine how the islands came to be occupied by different species of lizards. It...

Students explore the evolution of the anole lizard in this virtual lab. Students will collect and analyze data during the virtual lab that focuses on evolutionary biology and includes adaptation, convergent evolution, phylogenetic...

This simulation allows students to take on the role of a bird and eat different types of peppered moths. Students analyze which types of peppered moths do better in various environments.

Use molecular information and observe female response patterns to learn about the mating calls of Physalaemus frogs. Examine the evolution of female preference for particular call characteristics.

Great site that provides all types of information on fish ranging from fish ecology to funky fish. Entails links to sites on fish evolution and morphology.

In this biology inquiry lab, students study evolutionary relationships by making observations of preserved animal specimens, developing a question, then investigating by dissecting the specimens provided. This comparative approach offers...
