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...

What caused the dust bowl, and should we worry about it happening again? Scholars look at various data to come up with their hypotheses. Then, they experiment to find some of the factors that contributed. Finally, the video has them look...

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...

Island exploration—sounds exotic! During these three activities, high school learners explore island biogeography through a game and then analyze data collected, ask questions via BioBlitz, and present findings. Then, they must convince...

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...

Are you having trouble deciphering the Next Generation Science Standards on the website, or just trying to find the standards for your grade in a quick-and-easy format? If so, here is a free and easy-to-navigate app made with you in mind.

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...

How does biodiversity affect ecosystems? An insightful presentation covers the concept of biodiversity and its importance. It takes a look at extinction and endangered and threatened species as well as biodiversity hot spots around the...

How do populations grow and change? Scholars define demographics and identify trends in human population growth and learn how to make predictions about population size based on data analysis. Learners then explore the concepts of age...
