In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

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...

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...

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...

On the Caribbean islands, lizards expanded into different niches instead of competing for resources. Scholars discuss and learn from experts in a video how scientists prove the theory. They build phylogenetic trees based on appearances...

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...

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

How does the Earth continually repair itself? Explore the answer to this question, and others, with a unit on plate boundaries and interaction. Pupils classify the types of movement at plate boundaries and identify the...

What does it take to create a scientific theory? Learners attempt to answer the question by studying the work of Charles Darwin and Alfred Russel Wallace. While watching a video, they track observations from each scientist and then look...

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

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,...

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....

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...

Understanding how viruses spread has never been more important. A well-designed WebQuest lesson has young scientists research viruses, how they spread, and how they are treated. They also consider the trends in common viruses in the world.

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...

As part of a larger online exhibit answering the question, What is evolution, this site examines the specific theory of evolution with immediate attention given to exploring and defining morphs.

Explore the Black History in America in the lives of famous African Americans. Features include a clickable interactive timeline that highlights important events, accomplishments, and personalities from 1492 to 2001.

This site explores what Hardy-Weinberg Equilibrium is, and how teachers can explore this topic in their classrooms. Content includes background information on this topic, as well as numerous learning activities.

How much do you know about our early ancestors? In this activity you will explore our early ancestors and the evolutionary processes that led to human evolution.

EvoDots lets the user explore the mechanism of evolution. The program creates a population of dots. The user is a predator. As the dots run around the screen, the user eats them by clicking on them with the mouse. After the user has...

Students explore eight major phyla of the animal kingdom by comparing body plans, animal behavior, evolution, reproduction, and more. Includes a one-page reference to characteristics by phylum.
