JGI Nitrosomonas europaea ATcC 19718
As part of the DOE initiative to explore the role of microorganisms in global carbon sequestration, the Joint Genome Institute is sequencing the autotrophic nitrifying bacterium Nitrosomonas europaea. This organism plays a central role in the availability of nitrogen to plants and hence in limiting C02 fixation. These bacteria are important players in the treatment of industrial and sewage waste in the first step of oxidizing ammonia to nitrate.

Science Sampler : Fossil detectives
Middle school students are transformed into Fossil detectives as they examine the fossil record and use evidence about paleo-environments to develop an understanding of structure and function in living systems and changes over time in Earths history. In this enrichment activity, students work in teams to research an assigned geologic time period. They determine available habitats, food sources and types (animal, plant; woody, herbaceous, etc.), cover sources, methods of getting food, defense, an
Scope on Safety : Collaborating safely
With the advent of inclusion legislation such as the Individuals with Disabilities Education Act (IDEA) or PL 105-17 Reauthorization Action of 1997, many schools have focused on teaching partnerships between regular education and special education teachers. Science departments have been no exception to the trend toward team-teaching. This article describes five of the most popular models of team teaching. In addition, the legal implications and science safety issues concerning collaboration are
King Leads the March on Washington
the March on Washington (3:10) On August 28, 1963, a quarter million people gather to support civil rights, and share Dr. King's "dream" of equality. This video is highlighted by King's "I have a dream speech" and the reaction to it. The efforts of the federal government to enforce civil rights is explained as well as how the March was organized and where.
Visible Light and the Electromagnetic Spectrum
In this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications.
Energy in our Lives Carousel
This activity is way for students to discover that they already know a lot about energy through their own life experiences. They are active consumers of various forms of energy and are aware of energy purchases for transportation, electricity and (possibly) home heating. A pedagogical technique of a “carousel” is used to get all students involved in brainstorming and contributing ideas. The goal is to introduce students to some key terms and issues associated with energy as a necessary prere
Riding the Radio Waves
Through this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the amplitude and frequency of a given waveform. Students then learn general concepts about magnetic fields, leading into how radio waves are created and transmitted. Several demonstrations can be performed in order to help students better understand these concepts.
Franklin Roosevelt -Days in the White House
This is a film documentary about Franklin Delano Roosevelt from the 2008 WMHT documentary 'Presidents in Our Backyard' focuses on his days in the White House. Interesting images from the film: the only three known photographs of Roosevelt in a wheelchair.

Astronomy magazine senior editor Michael Bakich takes you on tour of the constellation Scorpius in this video. He compares Scorpius to other constellations and give you detailed information about the stars that make up Scorpius. Run time 08:33.
5.3 Global warming
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef
This Week on C9: Random Musings of Jeff and Charles This week on Channel 9, Dan and Brian aren't on This Week on Channel 9. No, ladies and gentlemen, not this week.
