How Bicycles are Made
This 5:25 long video tells the history of bicycles and how new ones are made.
Ulcerative Colitis (Spanish)
This patient education program discusses ulcerative colitis and explains the anatomy of the digestive system, causes, symptoms, diagnosis, and treatment options for this disease. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
Mozambique Floods from Landsat
Contrasting Mozambique before (August 22, 1999) and after (March 1, 2000) flooding.
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
An invitation for Cindy
At the completion of this lesson you will be able to send out an invitation card to a friend, you will listen to specific information. You will be able to infer the meaning of unknown words.
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.
3.3.4 The importance of other people in our immediate social and learning environments Yes, I had a lot of support from my family. You know, I suppose you could say you take that for granted but, yes, I did have a lot of support from my family. But in terms of feedback and a sounding board – colleagues for instance over the phone. Your tutor is another example.

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.
Williamsburg's jail, or gaol, set the standard for colonial prison architecture. Visit the building this year as we celebrate the 75th anniversary of its reconstruction. Architectural historian Carl Lounsbury describes the structure.Author(s):
Op het einde van deze les kun je inhoudelijke vragen beantwoorden na het beluisteren van een fragment over de Blitz tijdens WO II in Groot-Brittannië.
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)
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
There are several ways to create a Microsoft Access query that is based upon more than one table, and one way is to use the query wizard. Find out how to create a query that uses more than one table by going into query design
