Designing an Earth System Course
This Starting Point module describes the process of putting together a course in Earth System Science course. Users will find information on what an ESS course is, why this approach is useful and how to actually create the class. This module supports faculty efforts to structure Earth system science education not only to the needs of geoscience majors, but a variety of different audiences, from non-science majors to pre-service teachers.
Daisy World Model
The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary

As we search for life in the universe, it is essential that we be able to identify the chemical composition of planets and moons both inside and outside our Solar System. Remote sensing is one of the most valuable tools that scientists use to gather information about the composition of distant objects. In this lesson, students discover how remote sensing is used to identify the signatures of life even when the particular life form is not directly observable.
Who Can Live Here? Life in Extreme Environments
Astrobiology in the Classroom leads students in the exploration of the limits of life on Earth to extend their beliefs about life to include its possibility on other worlds. In this four-part activity, students first explore the environments of several mammals and birds to better understand how living things and their environments interact and depend on each other. In the second part, students match bacterial types with their more extreme environments. Students discover that an environment's tem

The Cells Alive Web site (last mentioned in the October 25, 1996 Scout Report), offered by Quill Graphics, contains several activities to help students understand the basics of cellular biology. The animal cell cycle and cell mitosis animations are especially excellent visual learning tools, clearly showing what takes place during these events and giving well-written descriptions of each stage. The site also has three interactive quizzes on cell structure, cell function, microbes, and the immune
Middle School Portal: Math and Science Pathways (MSP2)
Hosted by the Access Excellence at the National Health Museum, this website features A Walk Through the Gut, a lesson created for high school students by educator VivianLee Ward. This hands-on lesson promotes cooperative learning by directing students to work together as they simulate and analyze the passage of food through the digestive system. Ms. Ward designed this one-hour life sciences lesson for special education and special needs students as well. The site includes short sections on Mater
Bar codes : can you decode a barcode?
In this activity, students are shown a key to the post office conversion code and given a bar coded zip code to decipher. The activity, part of the Figure This! collection of 80 math challenges emphasizing math in the real world, introduces the bar-coding system and explains how the system enables businesses and banks to run more efficiently. The Hint suggests that students group the long and short bars into sets of five and then refer to the key to see what number is being represented. Related
Nutrition, Inequality and Agriculture: Contested Models of Degenerative Disease in Chiapas, Mexico
The industrial agro-food system has had two significant impacts on world public health: deteriorating human and animal nutrition due to poor food quality and the emergence of new infectious diseases arising from industrial animal production facilities and centralized food processing facilities. This situation is widely misrepresented in media coverage of public health issues. The corporate food system promotes the consumption of high levels of animal protein and processed foods
