The Microbial Biorealm
The Microbial Biorealm is an informational site about microbes written by students for students. Hosted by Kenyon College, the site includes molecular and taxonomic information about microbes from all three domains of life. A comprehensive table lists the properties and characteristics of each domain of life while taxonomy pages list classification, description, significance, genome structure, cell structure, metabolism, ecology, isolation, cultivation, and references specific to individual taxa
This Web site from the National Center for Biotechnology Information (NCBI) offers a set of detailed tutorials to help users make full use of NCBI's bioinformatics tools. The tutorials, which target both new and veteran users, cover NCBI's BLAST and PSI-BLAST, Entrez data retrieval system, Cn3D molecular structure software, and more. Additionally, the Science Primer tutorial offers a "basic introduction to the science underlying NCBI resources" geared more toward the general reader.
Northern Fur Seal Information
This National Marine Mammal Laboratory website provides links to detailed information about the distribution of fur seals in the Bering Sea region. It also features related links that lead to maps of fur seal rookeries on St. Paul Island and St. George Island, as well as PDF reports that describe fur seal population dynamics from 1993-2001.
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
Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters.
Anisotropic Oscillator Model
The EJS Anisotropic Oscillator model displays the dynamics of a mass connected to two opposing springs. The simulation displays the motion of the mass as well as the trajectory plot. The initial position of the mass can be changed by dragging. The unstretched lengths of the springs can changed as well via textboxes.
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
Molecular Dynamics Demonstration Model
The EJS Molecular Dynamics Demonstration model is constructed using the Lennard-Jones potential truncated at a distance of 3 molecular diameters. The motion of the molecules is governed by Newton's laws, approximated using the Verlet algorithm with the indicated Time step. For sufficiently small time steps dt, the system's total energy should be approximately conserved. Users can select various initial configurations using the drop down menu.
Ejs TPT Ladder Demonstration Model
The EJS TPT Ladder Demonstration model displays the statics and dynamics of a ladder leaning against a wall. The standard (textbook) statement of this problem assumes that there is no frictional force between the wall and the ladder, but a frictional force between the ground and the ladder. In the simulation you can set the initial lean angle and the coefficients of static and kinetic friction between the floor and the ladder.
Circumnavigating Pendulum Model
The EJS Circumnavigating Pendulum model displays the dynamics of a mechanical oscillator in uniform circular motion. The mechanical oscillator is free to move in two directions. This 2-dimensional simulation displays all the dynamical features of the Foucault pendulum, except for the dependency of the Foucault pendulum precession on latitude. The simulation shows simultaneously the motion with respect to the inertial coordinate system, and the motion as seen from a co-rotating point of view.
Newton's Second Law
This lesson introduces students to Sir Isaac Newton's Second Law of Motion. Topics include the two ways to study the dynamics of a system in which there is motion and a brief description of Newton's work in studying and measuring the motion of objects.
Understanding Your Water
Over two class periods, you will be guiding your students through the basics of water treatment -- both tap water treatment and sewage (or wastewater) treatment. To prepare for the lessons on the treatment process, the students will be researching where their drinking water comes from and where their wastewater goes once it goes down the drain for homework. After learning about their local water treatment and traditional tap water and sewage treatment processes, students will watch the NewsHour
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
Mixed Reception Scenario
This activity is set in a research group that is developing an antivenom for spider bites. In the opening scene, Nelson Pogline, a talented graduate student, dies unexpectedly at a university reception. As a detective, you must use chemistry concepts to determine if this was murder and if so, solve the case. You can interview suspects using Quicktime movies, investigate the crime scene for clues with Quicktime Virtual Reality images, and analyze the evidence from the crime lab. This activity req
We are now ready to pull everything we know about reaction stoichiometry together, and answer the question: Given some initial amount of reactants, what should be present after a chemical reaction goes to completion? The procedure for answering this question is often called the "limiting reagent problem." You'll see why this name is appropriate in the following video.
AP Environmental Science
Welcome to the NROC Advanced Placement (AP) Environmental Science course. This curriculum covers all of the material outlined by the College Board as necessary to prepare students to pass the AP Environmental Science exam. This course is designed to acquaint you with the physical, ecological, social, and political principles of environmental science. The scientific method is used to analyze and understand the inter-relationships between humans and the natural environment. The course shows how ec
American Women's Dime Novel Project
Dime novels written by women were once enormously popular with their readers, but the genre has been neglected for most of its history by scholars, collectors, and libraries. The genre suffers from the double burden of being both popular and written for working-class women. This project hopes to overcome the history of oversight to both the form and its readers by providing information about the novels themselves, the authors, the readers, and nineteenth century public reaction. This site is a
Pelvis (Part 3) Tutorial
Video uses hand drawn diagrams to identify and discuss the structure and physiology of the pelvis. Focus on os-coxa bone. Good review for a test. Music in background is a little distracting, and video is a little blurry. Grades 9-12. 4:39 min.
Linkage Mapping a Mutation in Arabidopsis
Since Alfred Sturtevant constructed the first genetic map of a Drosophilachromosome in 1913, new mutations have been mapped using his method of linkage analysis. Determining the map position of a new mutation -- and its corresponding gene -- consists of testing for linkage with a number of previously mapped genes or DNA markers. Linkage is the principle that the closer two genes or markers are located to one another on a chromosome, the greater the chance that they will be inherited together as
