Bioterrorism: plague as a biological weapon
Bioterrorism is the utilization of microorganisms or toxins in order to produce a disease and/or death in human beings, animals or plants. Different from conventional weaponry, relatively economic means are used that allow the elimination of living beings without destroying the surrounding atmosphere. The most probably method for spread of bioweapons is aerial transmission, continuing into water supplies and food. The CDC (US Centers for Disease Control and Prevention, Atlanta) has subdivided in

Investigating the Dynamic Martian Polar Caps
In this activity, students download NASA Hubble Space Telescope (HST) images of the Martian polar ice caps in summer and winter. Using image processing techniques, students measure and compare various images of the changing Martian and Earth polar ice caps.
Plant Cycles: Photosynthesis & Transpiration
What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of mo
California Spotted Owl
Owls sit high in trees and use their head-turning ability to search for food such as snakes, spiders, and small rodents (skunks, mice, and chipmunks). They do not eat plants and are considered carnviores.
Caecilian

"I Had to Break the Law to Force Him to Comply:" Lillian Roberts Recalls Organizing State Hospital W
Lillian Roberts came to New York in 1965 during a peak in labor militancy led by state and municipal government employees. Teachers, social workers, and sanitation workers all fought for better working conditions, improved pay scales, and reformed social services. Roberts, an African-American woman from Chicago, was an organizer for the American Federation of State, County, and Municipal Employees (AFSCME), and helped AFSCME's local D.C. 37 win the right to represent thousands of hospital employ
Visual Datasets
The Visual Datasets text module discusses the concept of visual learning and presents some suggestions for ways to design learning environments that support students in developing visual literacy skills. Three visual datasets that can be used for problem solving activities in evolution, classification, development, and botany are included:

Oceans, climate and weather
What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation.
This publication is all about developing your students’ understandings of earth’s oceans and the major effect they have on climate. Understanding and interpreting local weather data and understanding the relationship between weather and climate are important first steps to understanding larger-scale gl
