Biology
In this biology video, the instructor introduces the four main concepts behind Biology approved by The College Board—evolution, free energy, information, and systems. Individuals then listen to and see descriptions and examples of each...

Plants
Use a biology video to focus on four main groups of plants: bryophytes, ferns, gymnosperms, and anglosperms. It explains the parts of plants, life cyles, evolution of plants, and even touches upon sporophyte and gametophyte.

Natural Selection
Between 1968 and 2002, the total number of peppered moths decreased by almost two thirds, although scientists do now know why. In the 10th video of the series, the instructor defines evolution as any changes to a gene pool. Scholars then...

r and K Selection
Some species have one gender that is r-selected while the other is K-selected. A video focuses on growth rate and the difference between r-selected species and K-selected species. It includes a discussion of fecundity and carrying...

Population Variation
Tasmanian devils are scavengers who eat dead animals including the bones and fur. A video begins with cancer in Tasmanian devils to demonstrate the importance of genetic variation. Then examples such as the black-footed ferret and AIDS...

Environmental Matter Exchange
Why did carbon marry hydrogen? They bonded well from the minute they met. Here is a video that focuses on the essential chemicals for life: water, carbon, nitrogen, and phosphorus. It relates each of these to macromolecules and the way...
Bozeman Science
Ecosystem Change
Climate change has happened throughout the history of the planet, and the video uses examples from continental drift to modern airplanes as measurable examples. It begins with how climate change will impact systems on the...

Biodiversity
"The one process ongoing that will take millions of years to correct is the loss of genetic and species diversity by destruction of natural habitats" - E.O. Wilson. Here is a video that discusses biodiversity at multiple levels from...

Plant and Animal Defense
Explain the defense systems of both plants and animals against pathogens with a biology video. It covers the disruption of the immune system through hypersensitive responses, normal responses, nonspecific immune responses, as well as the...
Bozeman Science
Viral Replication
Explain how viruses use the lytic and lysogenic cycles with an explanatory video. The resource also describes retroviruses and the virulence of bacteria.
Bozeman Science
Examples of Natural Selection
Viewers explore real-world examples of both evolution and natural selection as the instructor discusses changes to the environment, mutations causing changes in phenotypes and changing the fitness in organisms, and how humans are...

Evidence for Evolution II
Some scientists believe humans are no longer evolving and have reached their evolutionary peak. In the video, scholars explore Darwin and his published work, The Origin of Species. The instructor discusses Darwin's ideas of biogeography,...
Bozeman Science
Scientific Evidence for Evolution
Humans share about 50% of their genes with a banana. In the video, scholars analyze the scientific evidence for evolution. The instructor spends time discussing Darwin and biogeography, fossils, and homologous structures. Scholars then...

Cladograms
No, a cladogram is not a new mass measurement beyond kilo. In the video, scholars watch as a simple cladogram is constructed consisting of seven organisms with shared characteristics. From this, the instructor asks where a new organism...
Bozeman Science
Law of Superposition
Scholars learn how rock layers, shift, and move over time. The instructor shows viewers how to solve geologic problems to determine the order of rock layers from oldest to youngest through a drawing video and then actual...
Bozeman Science
Secret of Life
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.

Stickleback Evolution
About 70 percent of the genes of the stickleback fish are the same as humans. In the video, scholars further explore the stickleback fish and its history, from being removed from Loberg Lake to their change and comeback. Over time, these...

The Operon
Operons operate on sections of genes. A video begins by explaining that operons are located mainly in bacteria, specifically focusing on lac operon. This lac operon, found in E.coli, breaks down lactose. It then shows how lac operon...
