The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

You've probably spent plenty of time discussing animal adaptations with your young biologists, but what about human adaptations? Explore the evolving traits of humankind through an interactive that combines text and video clips. Scholars...

When you get to the heart of the matter, you learn a lot about an organism by studying its circulatory system! A perfect resource for a zoology or anatomy class, the simulation gives users a peek inside a variety of vertebrates to...

DNA writes 64 different words but only codes for 20 different amino acids. Budding scientists learn about where each of these numbers come from and why they aren't equal with an online interactive. The resource explains the research, the...

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

What is DNA metabarcoding? Show your biology class the latest method for studying biodiversity in an ecosystem with a fun, informative interactive. Individuals examine the animal species that compete for vegetation, then learn how their...

Why are so many inherited diseases more prevalent in populations of specified races? Scholars learn about pedigrees and genetics using a reading, an animation, primary sourced letters, a short video, a biography, a guided practice...

Frederick Sanger won two Nobel prizes for protein sequencing and DNA sequencing. Young scientists learn about Dr. Sanger's research and amazing discoveries. They read an article and a biography, view videos and animations, and apply...

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...

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...

For years, scientists believed tRNA was junk left over from larger RNA. Three scientists used different approaches to prove tRNA actually exists as the connection between DNA and protein. Learn about their experiments, their lives, and...

In the 1940s, scientists discovered bacteria conjugation, the process of DNA transfer or bacterial sex. The discovery proved that bacteria and viruses contain DNA and led to a Nobel prize. Interested individuals learn about the...

Young scientists begin a field journal by following four steps. A real-world example of an entry showcases the different parts, including location, date, drawings, and more. 

Match up the DNA code. Pupils read the website from the American Museum of Natural History about how DNA can determine whether a skin is from a particular type of reptile. Using the same technique, learners match up products with the...

How did that turkey get from the early Aztec culture to your table? Learn about the history of wild and domesticated turkeys in North America, as well as their inclusion in Thanksgiving traditions, with a two-part agricultural science...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

A tutorial on genetic engineering. Students work their way through illustrations and animated tutorials about how genetic modification works and the ethical issues surrounding this scientific practice. The last two sections have...

Practice the steps of cloning in this interactive animation. Using what you know about somatic cell nuclear transfer, your mission is to create a genetically identical clone of Mimi, a brown female mouse. You'll answer a few questions at...

Find out what happened when Mendel crossed two hybrid pea plants. The animations do a good job explaining why these crosses produce a 3:1 ratio of traits.

A complete, student-paced lesson on genetics and inheritance. Students work their way through illustrations and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end of the lesson.

Create a Snurfle and see whether it can survive in different environments. As you play the game, you will learn about natural selection and animal adaptations. At the end of the game, try the multiple-choice quiz to check your...

Read a passage about recombinant DNA technology and answer the follow-up questions.
