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...

How would you feel if you made a huge scientific discovery, published it everywhere, and shared it with every scientist, only to have it ignored for 35 years because no one understood your genius? Unfortunately, Gregor Mendel died before...

Leukemia afflicts children more than any other type of cancer. Pupils explore the nature of harmful mutations in cell DNA, the reproduction of damaged cells in blood and bone marrow, and their effect on normal functions of the human body.

Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...

Let the games grow. Groups play a card game to grow cells. Players start growing cells from stem cells to create specialized cells in the human body. Learners use full-grown cells from the human body to create stem cells in the lab to...

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...

Regulatory genes play very important roles in cell development. An animated video shows pupils an example of a regulatory gene and how p53 initiates transcription of a gene. The parts of a gene that control regulation are briefly...

Bacteria are pesky little organisms that can often easily infect us. But how? Salmonella bacteria literally gets under our skin. Viewers see how the dangerous bacteria protects itself from defense mechanisms inside the cell.

Curing cancer with ... another virus? Chemotherapy and radiation are not the only ways to treat cancer. Now, there is a unique treatment involving infecting cells with viruses. Viewers discover why the innovative treatment does not...

A presentation of how engineering based in making something better led to engineering genetics. Scholars learn that genetic engineering began by selectively breeding plants that had specific characteristics to improve them. The video...

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

What is a proteasome? Like tiny trash compactors inside cells, proteasomes turn worn-out proteins into reusable amino acids! Explore the topic with a presentation and embedded simulations. The resource includes a teacher's reference and...

Many define biology as the study of life but can't agree on a definition of life. Trying to explain all of the domains and subdomains of biology seems a bit easier than defining life. See a full map of the topics covered by the general...

Cell division, cell expansion, and cell growth all take place in the cytoplasm exclusively. Young biologists learn about the role of cytoplasmic factors in cell development through and animated video.

Seeing is believing! Viewers observe the latest in technology—the ability to watch as a protein molecule searches for the appropriate binding site on a DNA molecule! A short video follows transcription factors SOX2 and OCT4 in their...

Is our skin color determined only by genetics? Explore skin science through a video and related interactive. Young biologists discover the cells of the epidermis, how melanin is made, and the factors that influence the outward appearance...

Are people inherently selfish? A video summary of Richard Dawkins' The Selfish Gene discusses how biology plays a role in selfishness. Part of a larger playlist the summary incorporates graphics and relevant examples to help make the...

The ancient Romans use the saying "When a mule foals" as a metaphor for the impossible. Viewers learn through a video lesson the genetics behind hybrid breeding, giving more meaning to this saying. The instructor explains the...
