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...

It doesn't matter if you look on land, in the air, underground, or in water—evolution is everywhere. Scholars complete worksheets with multiple question types as they progress through six online missions creating phylogenic trees. 

Many scholars study phylogenetic trees without understanding how they are made. Through an online game, young scientists use the given data to create phylogenetic trees of increasing complexity. They rely on the trees they create to...

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...

Geologists are gneiss, tuff, and a little bit wacke. The fifth chapter of seven includes ten activities at four different levels. The hands-on activities cover fossils including how they are formed, vertebrates, invertebrates,...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

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...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

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...

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...

A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about...

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...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

It's not often that you come across a clever laboratory activity that is both imaginative and comprehensive! Using M&M's and Reese's peanut butter candies to represent two different clam species, young biologists test for "relative...

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...

It's all in the cards. Using cards to simulate a disease's attack on the immune system, pupils develop an understanding of how the immune system and pathogens react to each other and why at times the pathogen wins. Groups play a game to...

Curriculum resources can be expensive—but not this one. An online textbook offers informational text for a complete high school Biology course. Topics include energy flow, body system, genetics, and evolution.

One important skill in analyzing scientific evidence is identifying facts versus opinions. Scholars identify pieces of evidence from the film The Day the Mesozoic Died and then discuss this evidence in small groups at the end of each act...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

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...

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...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...
