Regulation of the Lactase Gene
All human infants are lactose tolerant, yet some adults are lactose intolerant—why is that? Individuals discover the process of gene mutation through a study of the lactase gene (LCT). They understand the geographic connections,...
Howard Hughes Medical Institute
Biodiversity and Evolutionary Trees
Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...

Biochemistry and Cell Signaling Pathway of the Mc1r Gene
How do mice have so much fur color variation over generations? Scholars illustrate protein structures based on amino acid sequences. Then, they analyze the signaling pathway in different-colored mice populations. This allows them to...
Howard Hughes Medical Institute
Color Variation Over Time in Rock Pocket Mouse Populations
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...
Howard Hughes Medical Institute
Color Variation Over Time in Rock Pocket Mouse Populations
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...
Utah Education Network (UEN)
Utah Open Textbook: 7th Grade Science
Physical and biological factors affect everyday living. Scholars explore electromagnetic forces, motion, the rock cycle, and geological changes. They examine cells as the building blocks of life and how organisms reproduce using images...
College Board
AP Biology Practice Exam 2013
What is the best way to prepare for an AP® exam? Learners become familiar with the AP® Biology exam by completing a full-length practice exam. The AP® test prep by the College Board contains multiple choice, grid-in, and free-response...

Icefish Blood Adaptations: Antifreeze Proteins
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...
Curated OER
But, Why Sex?
Students investigate the importance of sexual reproduction in evolution. In this sexual reproduction lesson plan, students simulate species with two traits: eye and skin color. They determine what characteristics are beneficial for the...
