This video segment from the Nevada Department of Wildlife looks at various species of bats and how they impact the environment.

This Nature video segment focuses on the four foods most important to the grizzly bears' survival, and it describes the threats to the supply of each of them.

In this video segment from Nature, learn about the problems bears are creating on ranch land surrounding Yellowstone National Park.

This Nature video segment explores how the relationship between humans and grizzly bears has changed over the course of American History, and it describes the closing of the Yellowstone National Park garbage dumps in the 1970s.

Learn about the precautions humans must take in the face of a growing grizzly bear population in this video from Nature.

This video segment explores the world of the beaver, including the biology of the species and, more importantly, its ability to transform an ecosystem for its own benefit.

This video segment describes how the Australopithecus afarensis skeleton known as Lucy could have been fossilized. Footage courtesy of NOVA: "In Search of Human Origins."

This video segment from NOVA: "The Mystery of Animal Pathfinders" explores honeybee communication and navigation.

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

This is an activity that involves students modeling the behavior and competition that Charles Darwin's finches would have gone through as they competed for food and space on the Galapagos Islands. Some will survive. Some won't.

Cocos Island, a remote volcanic summit in the middle of the Pacific Ocean, serves as a beacon for hungry predators, including thousands of hammerhead sharks that travel here each year in search of prey. This video segment from NOVA: "Island of Sharks" depicts some of the common predator-prey interactions that take place in the nutrient-rich waters surrounding the island.

In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings. Learners experiment with the speed of rotation and direction of rotation to observe varying patterns. Use this activity to explain to learners how our eyes detect color and how different color receptors in the eye respond at different rates.

Learners research the effects of melting sea ice in the Bering Sea Ecosystem. They create research proposals to earn a place on the scientific research vessel Healy and present their findings and proposals to a Research Board committee.

The curriculum builds upon many years of educating our students in the garden and scales up content across grades and lessons for instructional scaffolding. It is designed as an interactive teaching tool to be co-taught with classroom teachers and garden instructors as leads. Each lesson connects directly to standards: Next Generation Science, Common Core State, Physical Education, and Environmental and Health Education. Our concise and easy-to-follow lessons are a packed 45 minutes for preschool through fifth grade. Flexibility is important to us, so some lessons include several activities that teachers can choose from to accommodate their lesson plans. Consistency is also important, so we follow themes and lesson structure found in the Curriculum Map.

Satellite observations that detect and map fires provide important insight into the widespread nature of fire activity around the world. This visualization, which shows global satellite observations of fires in 2002 and 2003, goes on to focus on a region where fire plays a dominant role in the landscape: Southern California. The wildfires that roared through Southern California in the autumns of 2003 and 2007 were particularly fast-burning and destructive because people have actively suppressed fires in the region where residential development is expanding further and further into wild land areas.

In this video segment adapted from NOVA scienceNOW, scientists discuss their attempts to grow human body parts in a jar.

This exercise contains two interrelated modules that introduce students to modern biological techniques in the area of Bioinformatics, which is the application of computer technology to the management of biological information. The need for Bioinformatics has arisen from the recent explosion of publicly available genomic information, such as that resulting from the Human Genome Project.

This video segment from Evolution: "Extinction!" shows the impact of invasive species on native ecosystems.

Biology 181 is a course focusing on the principles of biological science at the molecular and cellular level: the chemistry of life, cell structure and function, genetics and evolution.
