Design of a Primitive Nanofactory
This 86-page paper, published in October 2003, was written by the Director of Research at the Center for Responsible Nanotechnology. He proposes "an architecture for combining large numbers of programmable mechanochemical fabricators into a manufacturing system, or nanofactory, capable of producing a wide range of human-scale products." Rather than calling for the development of entirely new technologies, the author attempts to describe a system that can be built with current engineering practic

DiscoverySchool.com : Animal Instincts
Hosted by DiscoverySchool.coms Lesson Plans Library, this Animal Instincts lesson plan was created for fifth and sixth graders by Virginia elementary school teacher Jessie Kraft. The lesson teaches students about differences between instincts and learned behavior, the role instincts play in survival, and the relationship between environment and behavior. The site contains sections on Objectives, Materials, Discussion Questions, Evaluation, and more. Additionally, the site includes academic stand
Solving a problem
This informational piece, part of a series about the future of energy, introduces students to a three-stage process for problem solving. The three stages are identify the problem, test the solutions, and evaluate the results. A student tip sheet explains each stage and enables students to work through the processes in a step-by-step manner while seeing how the information is tied together. A graphic organizer provides students with an opportunity to evaluate the problem-solving solutions they ha
Observe an animation showing evidence of the carbon cycle
In this visual resource about the carbon cycle, students are presented with an animation and accompanying text that focus on carbon and plants. The text addresses how plants fit into the larger carbon cycle, including how carbon enters and leaves the biosphere, and it explains what students are viewing in the animation. The animation shows false color images on a flat map of the world. When the viewer clicks on the image (or the play button), the animation plays, and color patterns reveal change
Introduction to Capillary Chromatography
This site discusses many of the details in how ro convert a traditional HPLC system into a capillary HPLC system. Included in the discussion is how to use splitting to get to the lower flow rates required and how to pack your own capillary LC columns. There is detailed information on how to go about plumbing these sorts of systems (use of fittings, etc.), which may be valuable to someone who doesn't have that experience. The site also includes links to purchasing the components necessary for per

2.4 What does relationship mean in systematics? E. Mayr
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

The Imprisoner's Dilemma Imagine Life without Friction
<img src="http://mises.org/Controls/Media/DocumentImage.ashx?Id=6377" vspace="4" hspace="4" style="margin: 10px;" /><br />
Students are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down and eventually come to a stop. By severely limiting friction through the use of the hover pucks, students learn that the energy of one moving puck is transferred directly to another puck at rest when they collide. Students learn the concept of the conservation o
