The Wonders of Bacteria

The average AP Biology score dropped in 2018 with the addition of more data tables and graphs. Offer additional practice free-response questions by using the questions from the 2018 AP exam covering phylogenetic trees, cell structure and...

You don't have to be a scientist or even out of high school to contribute to scientific research. In the 12th lesson in the series of 21, scholars use this opportunity to add to the growing body of scientific knowledge and consider the...

Marine biologists research sea ice communities. Assign some groups to construct paper models of sea ice communities in winter, and some to construct models of them in summer. The lesson is simplistic, but the Internet resources provided...

Robert Koch and his team of scientists identified the germs that cause diphtheria, typhoid, pneumonia, gonorrhea, meningitis, whooping cough, tetanus, plague, leprosy, syphilis, and more—that's some important work! Over a period of 100...

Scientists try to understand the origins of life, and answers to these questions might be found during our lifetime. The fourth video in a 16-part series explains the earliest forms of life on Earth and their development. It covers...

Everyone in your class will be interested in marine biology after watching this video. A marine biologist at the Monterey Bay Aquarium Research Institute describes his daily duties. The details he includes in his narration are...

Information is provided on Gray's Reef, Florida Keys, and Flower Garden Banks marine sanctuaries. Young marine biologists then visit the FishBase and REEF databases to collect fish species information for each location. They then...

Explore how DNA, genes, and proteins are tied together to make life. Scholars learn about the central dogma, connecting DNA, which is inherited, to RNA and then to proteins, all which make the diversity of life today. 

The carrying capacity of an environment varies based on the organisms that live there. Using a virtual lab simulation, scholars test two protists living in their own environments and a third environment where both protists live....

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....
