CAT (Computerized Axial Tomography) scans
This web page about CAT (computerized axial tomography) scans gives a brief overview of this imaging technique. CAT (or CT) scanning captures a lot of 2-dimensional X-rays that a computer then joins together to generate 3-dimensional images of internal structures. As part of a set of materials about brain scanning technologies, this page mentions what researchers can learn about the brain from CAT scans. Copyright 2005 Eisenhower National Clearinghouse

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.

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.

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
