Modeling for Understanding in Science and Technology Education (MUSE)
The Modeling for Understanding in Science Education (MUSE) web site features science curricula consistent with the goals set forth in the National Science Education Standards and the Benchmarks for Scientific Literacy. The curricula and teacher's guides focus on astronomy (earth-moon-sun dynamics), evolutionary biology (natural selection) and classical genetics, with each unit unfolding over nine weeks. The product of a teacher-student-researcher collaboration and long-term research, the in-dept
Daughter from Danang: Culture Clash, a Perspective From Vietnam
The lesson focuses on the cultural differences and the impact to family structure and dynamics. A Vietnamese mother and her Amerasian daughter are reunited after 22 years. Both have dreamed of a joyful reunion but cultural differences and years of separation cause a different result. This film is about a war in the past and making peace in the present. The topics of culture, adoption and the meaning of family will be explored in this lesson.
Fuel Mystery Dis-Solved!
In this activity, students investigate the simulated use of solid rocket fuel by using an antacid tablet. Students observe the effect that surface area and temperature has on chemical reactions. Also, students compare the reaction time using two different reactants: water and vinegar. Finally, students report their results using a bar graph.
Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.
The Disaster Dynamics project is a learning environment for the study of the unique challenges surrounding natural disasters. By focusing on dynamics, this project emphasizes the complex and emergent interplay between different aspects of the design activities and the extreme event. The website has several educational role-playing simulation games such as decision making under uncertainty, complex systems and emergent properties, understanding design decisions and fostering collaborations.

Using Molecular Weight
A previous tutorial shows how to calculate the molecular weight of a substance from the atomic weights given. On this page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).
You can access the problems below via the Load Homework dialogue in the File menu of the Virtual Lab. They have been organized by concept and ranked by difficulty (A ranking of 1 denotes an easier problem; 5 is more challenging). Word files for these problems are provided so that you may edit and distribute the assignments in your classroom. The following types of problems can be found: Determining the Heat of Reactions in Aqueous Solution, Coffee, Coolant, Camping, ATP Reaction (Thermochemistry
You probably remember the mole from high school chemistry, but do you remember why it is useful to chemists? The goal of the following video is to give the "big picture" of the mole and its applications; information on how to use the mole in calculations can be found in another tutorial. Throughout this course, we will use the term "molecular weight" to refer to the mass of a mole of a substance (for instance, the molecular weight of oxygen (O2) is 32 g/mol). Recent textbooks refer to this as "m
Reaction stoichiometry allows us to determine the amount of substance that is consumed or produced by a reaction. The following video considers the first part of this: how much of a reactant is consumed in a chemical reaction. Product formation is discussed elsewhere.
Product Formation and Percent Yield
In another tutorial, we considered the amount of reactant consumed by a chemical reaction. Here, we'll consider the amount of product formed by a reaction.
1.46 Strategic Management in the Design and Construction Value Chain (MIT)
This course provides an overview of key concepts in strategic management in the construction, real estate, and architecture industries. Topics include supply chain analysis, market segmentation, vertical integration, competitive advantage, and industry transformation. This course is of interest to students seeking more understanding of the business dynamics of real estate and construction; seeking to provide value in firms which they may join; or seeking to build a foundation for their own entre
The Structures of Life
This site takes us into the world of structural biology -- a branch of molecular biology that focuses on the shape of nucleic acids and proteins (the molecules that do most of the work in our bodies). Learn about the structures and roles of proteins, tools used to study protein shapes, how proteins are used in designing new medications (for AIDS and arthritis), and what structural biology reveals about all life processes. Find out about careers in biomedical research.
Statics is a sophomore level engineering course, offered in all mechanical and civil engineering programs. Statics forms the essential pre-requisite to a number of follow-on courses, such as dynamics and mechanics of materials, and lays the foundation for design of mechanical systems. In most institutions, Statics is taught in a traditional way with an emphasis on the mathematical operations that are useful in its implementation, but without enough emphasis on modeling the interactions between r
Step by Step Glycolysis
You can browse the eleven steps of anaerobic glycolysis and view three kinds of information: reaction data (the enzyme, reaction type and thermodynamic data), equation and animation.

Case It! - case-study learning integrating molecular biology computer simulations and international
For introducing a framework for collaborative case-based learning in molecular biology using interactive computer simulations and web-based "poster sessions" for students via Internet conferencing.
Kinematics and dynamics are presented here in multimedia, at introductory and also at deeper levels. Individual video clips and animations are suitable for use by teachers, while students may use the whole package for self instruction or for reference.
This item addresses concepts such as: entropy, free energy, first law of thermodynamics, basic reaction kinetics.
