Medium levels of bismuth - the lighter coloured parts are mostly at eutectic composition.
The Siren Song of Cancer Cells
The treatment of complex diseases like cancer may lie in grasping their mechanisms at all levels of biological hierarchy. Most research focuses on understanding how genes cause cancer from within a cell, but much can be learned from intercell interaction.
Derelict site simulation
This Powerpoint driven simulation takes participants through a structured series of common dilemmas faced by managers looking after derelict sites. Risks must be appraised within resource constraints (and the influence of chance). Decisions taken affect subsequent events. Can you steer the site safely through this maze? The resource can be used in the teaching of lawyers about occupiers’ liability, as well as construction and real estate students and also environmental management students. The
Food Chains
This music video teaches about food chains and the pyramid of energy. Watch it a few times and you'll be completely on top of trophic levels and energy transfer. Â This video is a great learning tool for late elementary and middle school age students to help remember all the details that make food chains what they are.
18.969 Topics in Geometry: Mirror Symmetry (MIT)
This course will focus on various aspects of mirror symmetry. It is aimed at students who already have some basic knowledge in symplectic and complex geometry (18.966, or equivalent). The geometric concepts needed to formulate various mathematical versions of mirror symmetry will be introduced along the way, in variable levels of detail and rigor.
Peer Review of Teaching - Course Portfolio
In this course portfolio, Dan Bernstein reports on changes he has made over three semesters in a psychology course on learning. He has succeeded in getting more students to achieve higher levels of understanding by changing the assessment from short abstract essay questions to problems that asked students to apply concepts in new contexts, and providing web-based opportunities for students to identify what makes some answers better than others. The portfolio includes examples of the assessments
Virginia Schools in the Great Depression
This project provides teachers and students with free, online historical sources and instructional materials for teaching the history of the Great Depression in Virginia, using public schools as a case-study of how decision makers, the public, and educators responded to the crisis of the Depression.
The five educational modules available on this website address the following themes:
1. The Impact of the Depression on Virginia Public Schools
2. Who Should Bear the Burden? Public Opinion and Sc

The Keeling Curve Turns 50
The inception of the "Keeling Curve," a history of atmospheric carbon dioxide levels, marked a key moment in American science history. The record began in March, 1958 at a small observatory on the top of Hawaii's Mauna Loa.
The (Ralph) Keeling Curve
After two decades watching atmospheric oxygen levels drop, a Scripps researcher's conclusions about climate could leave one feeling light-headed.
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
Kinetic connections: Bloom's taxonomy in action
An introduction to strategies for using the web to push your students to higher levels of thinking.
Virtual Laboratory
The simulation program is based on the Nobel Prize winning Hodgkin-Huxley model for excitation of the squid axon. The program simulates an excised squid axon by applying stimuli or clamps after setting the environment of the axon, changing its properties, and/or adding drugs or toxins.
By using the program tools, experiments can be developed that explore a variety of nerve properties, ranging from classical phenomena such as threshold, summation, refractory period, and impulse propagation to mo
Commonwealth of Learning Copyright Audit
To a significant extent, copyright law governs the production, dissemination and consumption of knowledge and culture. In an "information society" it is particularly important to ensure that the gates of learning are kept wide open. It is in this context that an examination of copyright law with respect to education becomes crucial. When performing an audit of copyright law, it is essential to keep in mind international treaty obligations: particularly, the Berne Convention, the Agreement on tra
Module Four: Money Management
Money Management may be defined as the process of managing money, including investments, budgeting, banking, and taxes. Managing your money is an essential life skill. When you know what you're doing, it really isn't so difficult. Once you've left home, the only person responsible for your financial health is you, so it's good to know the essentials. Managing your money can help reduce the stress levels that you experience throughout your life. It can help you to plan for unexpected events and e
Who's Eating Who?
Developed for second grade. First the teacher will explain the 5 trophic levels of a food chain to the students using the hand out with the sample food chain (Figure 1). Then once they have learned about trophic levels, autotrophs, and heterotrophs, each student can begin looking through the magazines and cutting out pictures of animals to create their own food chain. Once each student has completed his or her food chain, you can have them share them with the group.

Macroeconomics for Managers
This course provides a broad overview of macroeconomic theory and policy. The focus is on understanding fluctuations in the levels of income, employment, and production and policy responses to these fluctuations.
Guide for Teaching About Coastal Wetlands
The intent of this material is to provide a basis from which a comprehensive study of coastal wetlands can be developed by the teacher on the basis of individual needs. Each teacher has students with varying needs and must, therefore, plan accordingly. The information and activities are provided as a framework and may be used and revised to accommodate different levels of students. Some activities may be used as demonstrations rather than student activities for younger students. Any grade level
Levels of measurement
Aimed at statistics beginners, this learning object describes, and gives examples of, the four levels of measurement of data: nominal, ordinal, interval and ratio.
