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.

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...

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...

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Teach your class how to get out of a cell — or break in. The third installment in a seven-part series introduces the class to cell membranes and their functions. The lesson plan includes information to present to the class,...

A cell phone isn't used for this cell communication. Use a video resource to overview three main types of cell junctions. It provides a graphic of each type and elaborates on each with a description. The last line expands upon the...

Does your class get confused when discussing osmosis and tonicity? Explore the relationship between osmosis and tonicity to further differentiate between the two processes. The lesson concludes with a class-led discussion about the topic.

Packed with visual aids and multiple learning opportunities, an engaging exercise challenges individuals as they explore the role of producers, consumers, and decomposers. After discussing differences between food chains, food...

Searching for exciting lesson plans filled with hands-on activities to use in your traditional classroom environment? Look no further! This set of lesson plans for AP Biology covers topics from genetics to evolution, botany to ecology,...

Why are Henrietta Lacks' cells immortal? The answer is that no one really knows. But much has been learned because they are. Check out this video that introduces some of these remarkable discoveries.
