Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

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....

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...

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....

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

In this environment worksheet, young scholars complete a series of multiple-choice and short-answer questions on genetics, populations, and cell structure.

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

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...

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...

The most popular AP science exam, Biology, also maintains the highest passing rate. The College Board releases old test questions covering trichomes and much more, along with statistics and scoring guidelines to help scholars study for...

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...

[Free Registration/Login may be required to access all resource tools.] Introduction to macroevolution, microevolution, and population genetics.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

A team of scientists studied the schooling behavior of threespine stickleback fish by experimentally testing how individual fish responded to an artificial fish school model.

Students discover that variation in plants allows some varieties to survive in near-drought conditions. Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection...
