Step by Step Krebs cycle
These pages show the steps of the metabolic pathway called the Tricarboxylic Acid (TCA) cycle. Otherwise known as the citric acid cycle and the Krebs cycle. Data sheets, reaction diagrams and animations are provided for each step. Krebs cycle or the citric acid cycle or tricarboxylic acid cycle,occurs in mitochondria, is the common pathway to completely oxidize fuel molecules which mostly is acetyl CoA ,the product from the oxidative decarboxylation of pyruvate. It enters the cycle and passes
Calculus on the Web
COW is an internet utility for learning and practicing calculus. The principal purpose of COW is to provide you, the student or interested user, with the opportunity to learn and practice problems in calculus (and in the future other topics in mathematics) in a friendly environment via the internet. The most important feature of the COW is that you get to know whether your answer is correct almost immediately. It is as if you had a tutor looking over your shoulder and helping you along as you wo
Studying mammals: food for thought
Who were our ancestors? How are apes and humans related? And where does the extinct Homo erectus fit into the puzzle? In this unit we will examine culture, tool use and social structure in both apes and humans to gain an understanding of where we come fro
Radioactive Decay Model
The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy. The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Creating People Centred Schools: Section One, Introducing the module
This introduction provides a rationale for the module, as well as its structure and content. We read how the writers intended the module to be used.
Medicine Games: Incredible Megacell Game
Play a game and find out about a Nobel Prize awarded discovery or work! The compartments of the cell, the organelles, are so small that it was impossible to study their structure until the electron microscope became available in 1938. Albert Claude, Christian de Duve and George E. Palade were awarded ...
Physics Games: Liquid Crystals
Play a game and find out about a Nobel Prize awarded discovery or work! A liquid crystal is a substance that flows like a liquid but maintains some of the ordered structure characteristic of crystals. In the 1960s, a French theoretical physicist, Pierre-Gilles de Gennes turned his interest to liquid ...
Bering Sea Climate
The Bering Sea Climate website contains time series data that measures climate and ecosystem status in the Bering Sea. The site presents data, metadata, and graphics by allowing the user to select categories and then click a button for the desired function. Data can be displayed as a list, a time series plot, or in terms of recent trends, relevance, and correlation. Measured parameters include weather, oceanographic and climate data, sea ice data, and fisheries and other biological data. The sit
Brighten Up the Classroom
provides papers on the aurora and ionosphere, scales for measuring space weather, and a textbook for high school teachers and advanced students -- Solar Physics and Terrestrial Effects. The textbook examines a range of topics: the evolution and structure of the sun, sunspots and solar flares, the corona and chromosphere, solar-terrestrial interactions, building a spectroscope, measuring the solar constant, and seeing at different wavelengths.

Structure of the Earth and the Origin of Magmas
This set of lecture notes covers several topics relating to the earth's interior. Seismic waves and the earth's internal structure are discussed. Several mechanisms for the origin of magma are offered. These lecture notes are in outline form with definitions and instructive diagrams. This resource is ...
Mid-Ocean Ridge Basalts
This PowerPoint presentation is part of the Whitman College petrology course. This 37-slide presentation starts by presenting a generalized map of the earth's rift system. The composition of mid-ocean ridge basalt is introduced in the context of major-element chemistry, petrography, trace elements, spreading rate, and isotope chemistry. Melt generation in terms of mantle and lithospheric structure is portrayed in a number of schematic diagrams. This resource is part of the Teaching Petrology col
"Introduction to Neuroscience, Fall 2007"
" This course is an introduction to the mammalian nervous system, with emphasis on the structure and function of the human brain. Topics include the function of nerve cells, sensory systems, control of movement, learning and memory, and diseases of the brain."
Aerodynamics: applications of force and flow
Although there is a great deal of historical information about aerodynamics that could be discussed here, we purposely narrowed the stream of resources to those that encourage students to experiment with technological design and function.
Math Literature Connections: Patterns and Algebra
Ideas and activities that use Two of Everything, One Grain of Rice and the King's Chessboard to introduce students to function machines and input/output tables. Links to appropriate templates are also provided.
Helping Students Understand Text Structures: Informational Problem/Solution
This exercise teaches students to understand the organizational structure of problem/solution essays by having them write "what it says" and "what it does" statements about a text. Asking students to write these statements about a text will enable students to read the text closely and will ensure that ...
Personal Preparedness Planning For Public Health Workers
Public health workers need to understand and implement basic concepts of personal preparedness planning so that they can function effectively as public health emergency responders in a post-9/11 world. These basic preparedness strategies can be applied to meet a broad range of public health emergency response challenges, including - but not limited to - acts of terrorism.
