This textbook is a reference text for General Chemistry, including the major concepts and ideas of chemical science, and a look at some of the major currents of modern Chemistry

A magician pours milk into a glass, but when he turns the glass upside down, nothing comes out. How does he do it? Discover the science behind the magic in this video adapted from the American Society of Mechanical Engineers.

Classification activities that will lead students from simple sorting of familiar objects to classifying materials into liquids, gases, and solids.

This subject provides an introduction to fluid mechanics. Students are introduced to and become familiar with all relevant physical properties and fundamental laws governing the behavior of fluids and learn how to solve a variety of problems of interest to civil and environmental engineers. While there is a chance to put skills from Calculus and Differential Equations to use in this subject, the emphasis is on physical understanding of why a fluid behaves the way it does. The aim is to make the students think as a fluid. In addition to relating a working knowledge of fluid mechanics, the subject prepares students for higher-level subjects in fluid dynamics.

This course introduces finite element methods for the analysis of solid, structural, fluid, field, and heat transfer problems. Steady-state, transient, and dynamic conditions are considered. Finite element methods and solution procedures for linear and nonlinear analyses are presented using largely physical arguments. The homework and a term project (for graduate students) involve use of the general purpose finite element analysis program ADINA. Applications include finite element analyses, modeling of problems, and interpretation of numerical results.

This course presents finite element theory and methods for general linear and nonlinear analyses. Reliable and effective finite element procedures are discussed with their applications to the solution of general problems in solid, structural, and fluid mechanics, heat and mass transfer, and fluid-structure interactions. The governing continuum mechanics equations, conservation laws, virtual work, and variational principles are used to establish effective finite element discretizations and the stability, accuracy, and convergence are discussed. The homework and the student-selected term project using the general-purpose finite element analysis program ADINA are important parts of the course.

The objective is to teach in a unified manner the fundamentals of finite element analysis of solids, structures and fluids. This includes the theoretical foundations and appropriate use of finite element methods.

Finite element analysis is now widely used for solving complex static and dynamic problems encountered in engineering and the sciences. In these two video courses, Professor K. J. Bathe, a researcher of world renown in the field of finite element analysis, teaches the basic principles used for effective finite element analysis, describes the general assumptions, and discusses the implementation of finite element procedures for linear and nonlinear analyses. These videos were produced in 1982 and 1986 by the MIT Center for Advanced Engineering Study.

The students will be able to define solids and liquids from their prior knowledge. The students will be able to verbalize the differences between solids and liquids? Observe, communicate and question when things aren't what they appear to be. Is Oobleck a solid or liquid? The answer is that it is both. Have the students come up with their own answers and to communicate their findings. The students will understand the difference between a non-Newtonian fluid and a liquid or a solid.

Scanning Probe Microscopy is an important tool for scientists and engineers. A classroom analogue constructed using Lego(R) building blocks is an effective way to represent how these tools work and to interpret the images produced by them. Background information for building a Lego(R) AFM and SPM are shown. Two laboratory activities are suggested, complete with advanced set-up information, pre-laboratory discussion, laboratory directions, and post-laboratory discussion. Instructions on making Surface Plots are included for Excel PRE 2007. More recent releases of Microsoft Excel no longer have this feature.

Introduction to continuum mechanics and material modeling of engineering materials based on first energy principles: deformation and strain; momentum balance, stress and stress states; elasticity and elasticity bounds; plasticity and yield design. Overarching theme is a unified mechanistic language using thermodynamics, which allows understanding, modeling and design of a large range of engineering materials.

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: dilution problems, Sucrose problem, Making Solutions from Solids, Metal Density problem, Liquid Density problem, Alcohol Density problem.

A molecular approach to biology must develop in students an understanding of molecules, their interactions and the consequences of these interactions. Biological phenomenon now more than ever rely on chemical and physical principles for molecular explanations of the phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.

" This subject is designed for upper level undergraduates and graduate students as an introduction to politics and the policy process in modern Japan. The semester is divided into two parts. After a two-week general introduction to Japan and to the dominant approaches to the study of Japanese history, politics and society, we will begin exploring five aspects of Japanese politics: party politics, electoral politics, interest group politics, bureaucratic politics, and policy, which will be broken up into seven additional sections. We will try to understand the ways in which the actors and institutions identified in the first part of the semester affect the policy process across a variety of issues areas."

This is an oceanography education journal consisting of current oceanography research conducted at NASA by NASA, NOAA, and university researchers and educators. This journal is a collection of articles, classroom activities, readings, teacher/student questions, imagery and much more designed for the grade 9-12 biology/environmental/earth science classroom. There is nothing out there like it and since we do a great deal of oceanographical research at Goddard Space Flight Center and the Wallops Flight Facility, we thought who better to put this together then our Hydrospheric and Biospheric Sciences Laboratory. We also have an accompanying web site that will eventually contain all the journal information, as well as future instrument data that can be scaled to the university level.

Eight questions to test your scientific knowledge of solids, liquids and gases

This video segment, adapted from ZOOM, explores how sound waves travel differently through air than through solids like a yardstick, a baseball bat, and a golf club.
