Researcher Mahesh Anand of The Open University's Centre for Earth, Planetary, Space and Astronomical Research (CEPSAR) is undertaking analysis of lunar basalt collected during the moon landings of the late 1960s and 1970s. The results may provide clues into the origins of the earth.
This information database provides an easy way of accessing the sequences and all-inclusive annotation data on the structures of the cyanobacterial genomes. Cyanobacteria carry a complete set of genes for oxygenic photosynthesis, and are believed to be the ancient ancestors of chloroplast. Maintained by the Kazusa DNA Research Institute, Cyanobase contains information and sequences for Synechocystis, Anabaena, Thermosynechococcus elongatus, Gloeobacter violaceus, Prochlorococcus marinus, Synecho
Soil Characterization Protocol
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.
Determining Dinosaur Speeds
This exercise has students determine how fast a dinosaur was moving based on the tracks it made. It allows students with minimal quantitative background to become motivated and begin to develop an appreciation for dimensional analysis as they see whether or not they could outrun the track-making dinosaurs. Measurements from any dinosaur track site can be used in this activity. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
An Assessment of Hillslope Stability Using the Factor of Safety
In this homework assignment, students consider the balance of forces on a hillslope using the Factor of Safety by calculating shear stress and shear strength for an example hillslope and formulating an expression for the factor of safety in an Excel spreadsheet. Students then use this spreadsheet to conduct a sensitivity analysis for the purpose of assessing which variables are most important in determining hillslope stability. A series of short answer questions guide students through this proce
20.441J Biomaterials-Tissue Interactions (MIT)
This course covers the principles of materials science and cell biology underlying the design of medical implants, artificial organs, and matrices for tissue engineering. Methods for biomaterials surface characterization and analysis of protein adsorption on biomaterials. Molecular and cellular interactions with biomaterials are analyzed in terms of unit cell processes, such as matrix synthesis, degradation, and contraction. Mechanisms underlying wound healing and tissue remodeling following imp

U.S. Constitution Workshop
This is a self-service online workshop for teachers that uses primary documents to help students see the impact and ongoing relevance of the Constitution. It requires little advance preparation and provides everything needed, including a vocabulary list, document analysis worksheets, and historical documents -- John Marshall's Supreme Court nomination (1801), proclamation to New Orleans (1803), Lincoln's telegram to Grant (1864), Johnson oath photo (1963), and more.
Introduction to macroeconomics
This is a module framework. It can be viewed online or downloaded as a zip file. As taught in Spring Semester 2010. This module provides an introduction to modern macroeconomic analysis. Macroeconomics is concerned with some of the most pressing and fundamental questions economists can ask, such as: What determines economic growth? Why do economies exhibit expansions ('booms') and contractions ('busts') in output? What drives employment and wages, saving and investment? What causes inflation
Small Business and Entrepreneurship
The objective of this course is to teach you to apply the skills you have learned in the functional areas toward the goal of starting a business, i.e., becoming an entrepreneur. Working in teams, you will learn to identify, conceptualize, plan, finance, launch, manage and harvest new ventures. Finally, intrapreneurship, the application of entrepreneurial methods of management to established organizations, will also be discussed. Class discussion, readings, case studies, guest speakers, interview
Entrepreneurship: The Real-Time Case Study
As you read this, the managers of a new high-tech company, (to be announced), are striving to achieve the entrepreneurial dream. On a special website you will follow that company, and see their progress week by week. But you will do more than just watch. You will be actively engaged with the company, analyzing its problems, and making input. You will be participating in an in-depth, real-time case study. Unlike traditional case studies, this real-time case will dig deeply into one company during
Home Energy Analysis
This is the second part of a two-part exercise in which students perform an audit and analysis of energy consumption in their homes. In this part, students will estimate the amount of energy they use in their homes and investigate how their lifestyle impact the environment.
Tracing Genetic Ancestry Using DNA Microarrays
In this lesson students will read and discuss an article about genetic ancestry and genetic ancestry testing. 2. Apply knowledge of DNA and heredity to understand DNA microarrays, and concepts of genetic mutation and ancestry tracking. 3. Mimic the function of a DNA microarray used for genetic ancestry analysis by completing a paper-and-pencil activity. 4. Discuss the ethics of genetic testing in medical research.
HIV and AIDS Prevention Education
This is a collection of resource packages suggesting how education systems can change their analysis and conduct in relation to HIV and AIDS. The site also contains manuals and booklets offering basic facts and information needed for the acquisition of knowledge and development of attitudes, values, skills and practices (KAVSP) related to the prevention and control of HIV/AIDS.
Resistan is a mechanistic simulation model of the process of selection of fungicide-resistant biotypes of a hypothetical fungal pathogen of a hypothetical crop. The fungus is a polycyclic organism with many generations per season. There is no genetic component in this simulator. Reproduction is assumed to be asexual. A small proportion of the initial inoculum is designated as the fungicide-resistant biotype at the start of the season, and the response of that population to various fungicide spr
Phylogenetic Investigator (PI) is a software package designed to facilitate creative problem-solving in phylogenetic analysis for the purpose of teaching and learning phylogenetic inference. Users can identify characters and states, polarize characters, and engage in directed-search phylogenetic tree construction. PI also allows the user to * make inferences and represent them one step at a time * vary representational features of their trees (such as angle of divergence and time betwee
