Lake Mead Shrinks!
Lake Mead reservoir is nestled between Arizona and Nevada and runs up to the Hoover Dam. The reservoir stores Colorado River water and supplies it to farms, homes and business in Southern Nevada, Arizona, southern California and northern Mexico. Scientists at NASA are releasing dramatic pictures of the dwindling water supplies in the drought-stricken western United States. According to the Bureau of Reclamation, the Colorado Basin is in its fourth year of drought and computer models project wate

Splish, Splash, I was Takin' a Bath!
In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.

Case Study: Levene
Not only bees pollinate flowers. Moths have a specialized mouth structure called a proboscis that is used to extract nectar and pollinate the flower. The moth benefits by getting food and the flower benefits by being pollinated.
Frogs eat insects, and frogs are in turn eaten by larger animals such as birds. Frogs hibernate, or more correctly, they estivate. During estivation, frogs lowers their body temperatures in cold weather and go into a kind of dormancy. Frogs can "migrate" in that they move across land to find ponds and water sources.

The Johns Hopkins Center for Bioengineering Innovation in the department for Biomedical Engineering at the Whiting School of Engineering hosts its annual Design Day to showcase student research.
Kinetic and potential energy of atoms result from the motion of electrons. When electrons are excited they move to a higher energy orbital farther away from the atom. The further the orbital is from the nucleus, the higher the potential energy of an electron at that energy level. When the electron returns to a low energy state, it releases the potential energy in the form of kinetic energy. (02:25)
Trees provide many animals, including humans, with food. Coconuts are just one of the several nuts and fruits that trees produce that are edible.
General Biology - Fall 2007. This is a general introduction to plant development, form, and function; population genetics, ecology, and evolution. Intended for students majoring in the biological sciences, but open to all qualified students. In general at the end of Biology 1B students will be able to: describe the scientific method and explain how it would be applied to a novel problem; explain the consequences of random variation when extrapolated over time; distinguish between positive and
