An eight-unit electronic textbook provides a guide to AP® Biology. Each of the 28 chapters include an introduction, multiple lessons, a summary, review questions, and test prep questions. Teachers see how each lesson connects to a big...

Can DNA fingerprinting prevent the extinction of elephants? Young scientists learn about DNA fingerprinting before applying their knowledge to case studies of elephant poaching. The first case requires them to match the DNA from a tusk...

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Do you have young scientists wanting to make new discoveries rather than just completing the same experiments? Young scientists use their observational skills to identify animals and patterns in animal behavior. Through tracking...

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...

An engaging unit on wildfires includes three sections, including a background section with eight lessons and five activities, a field experience section with 13 lessons and five activities, and a conclusion section featuring an analysis...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

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...

Explore the excitement and ethical challenges of CRISPR and genetic-editing technology. Participants engage in do-nows, view a slideshow, and collaborate on scenarios about genetic editing. Group members analyze scenarios to generate...

Develop an understanding of how climate change affects humans' health. The class lists what they know about climate change and its connection to disease and then read sections of an article providing specific details on how climate...

Stop the spread. Pupils work through two activities to gain an understanding of vaccines and immunity. Learners research different types of vaccines and how they are made and explore the advantages and disadvantages of them. Using a...

Scientific knowledge of genetic information has grown quickly over the last decade. An interactive lesson has learners research the role of science and medicine in diagnosing and treating genetic disorders. They consider the job of the...

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.

Make connections between ocean organisms. Individuals explore three different ecosystems in the ocean. With an online interactive, they learn how different organisms depend upon each other. Learners first answer questions to connect...

Put on those forest ranger hats for an engaging and informative lesson. Eager scientists study the makeup of a local forest ecosystem and then write a forest management plan. They consider many parameters including identification of both...

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...

Simple characteristic changes can have a significant impact on species survival. A hands-on activity has learners investigate the color variation in pocket mouse populations in different environments. They connect the timing and number...

What, exactly, causes lactose intolerance? Scholars view a video describing a Finnish study that determined why some people are tolerant while others are intolerant. They then use the data from the study to reenact the experiment and...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

An environmental factor, such as a drought, sometimes speeds up the rate of natural selection. Scholars analyze data on the beaks of birds around the time of the drought. They compare those that survived to those that perished and find...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...
