Protist Image Data
Protist Image Data (PID) is an online database that provides pictures and short descriptions of selected Protist genera, especially those genera whose species are frequently used as experimental organisms or are important in studies of organismal evolution. Up-to-date information is provided on the morphology, taxonomy and phylogenetic relationships of these organisms. Information on PID pages is arranged by the following: Introduction, Appearance, Ultrastructure, Reproduction and Life History,
Organisation of Pedestrian Movements: an Agent-Based Approach
Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one o
Operation Ruby Throat: The Hummingbird Project Protocol
The purpose of this resource is to observe seasonal migration patterns, feeding habits, and nesting behavior of Ruby-throated Hummingbirds (Archilochus colubris) in North and Central America. All students will learn about hummingbird natural history and ecology. Students will learn how to identify and age male and female Ruby-throated Hummingbirds and to observe migration and feeding behavior. Students will learn how to make connections among hummingbird behavior and weather, climate, food avail
Fossil Fuels: Oil
This lesson provides an introduction to the world oil market and the United States' dependence on it. Topics include our current usage, sources, and the political implications of acquiring oil from an international market.
Central to good science are accurate observations, testable hypotheses, well-designed experiments or other tests, and reasonable data analyses. The purpose of this activity is to introduce the basics of designing and analyzing experiments.
Drinking Water Treatment
This lesson provides an introduction to the treatment of drinking water to remove harmful or distasteful substances. Topics include the history of treatment and a brief listing of treatment processes.
Suffer the Little Children - Reflecting on Child Labor in Guatemala
In this lesson, students learn about and respond to the plight of child workers in Guatemala in the face of increased free trade through the Central American Free Trade Agreement.
Fifty Years: From the Little Rock Nine to the Jena Six.
In this lesson, students discuss how the issues surrounding school integration have changed since the Little Rock Nine entered Central High School and what the recent events in Jena, Louisiana, teach us about what issues we still face as a nation.
The Introduction to Cardiovascular Pathophysiology course provides the students with two main objectives. It delineates the material students are expected to understand and have recalled from the basic cardiac physiology lectures and it expands on the discussion of the hemodynamic perturbations of cardiac function.
Introduction to Clinical Pain Problems
Research of the mechanisms, nature, and treatment of pain has advanced enormously in the past decade. Introduction to Clinical Pain Problems is part of the Tufts University School of Medicine Master of Science in Pain Research, Education and Policy program. The program, founded in 1999 by an anesthesiology/internist and a sociologist, meets the needs of practicing health care professionals to provide optimal pain management by offering a unique, interdisciplinary program that sets the standard f
Sampling is a computer tool designed to help biology students obtain a qualitative understanding of basic concepts related to estimation and statistics. Sampling presents the user with a group of hypothetical populations distributed throughout an area, and with tools for sampling these populations to estimate characteristics such as population size and density, the nature of each population's spatial patterning, and spatial correlations in abundance between populations. By manipulating the numb
Data Collection and Organization
The Data Collection and Organization (DC&O) text module provides background on useful, general-purpose software tools. The aim is to discuss types of generic software that virtually every well-equipped scientist uses. This includes: spreadsheets, database programs, statistics packages, graphics programs, and word processors. DC&O includes several examples of the use of these tools in biology. These include 'An Embryological Example with Tips and Tricks' and the complete text and dataset of a cl
The Water Sourcebooks contain 324 activities for grades K-12 divided into four sections: K-2, 3-5, 5-8, and 9-12. Each section is divided into five chapters: Introduction to Water, Drinking Water and Wastewater Treatment, Surface Water Resources, Ground Water Resources, and Wetlands and Coastal Waters. This environmental education program explains the water management cycle using a balanced approach showing how it affects all aspects of the environment. All activities contain hands-on investigat
Math Literature Connections: Two of Everything
Two of Everything by Lily Toy Hong recounts a Chinese folk tale. The farmer finds a magic pot which doubles everything that is put into it. This humorous story is a great introduction to function machines and input/output tables as teachers make the transition to the "doubling pot" and recording information in an input/output table.
NASA CONNECT Team Extreme: The Statistics of Success
In NASA CONNECT, Team Extreme: The Statistics of Success, focuses on NASA's Space Operations Mission Directorate and the teamwork required to produce a successful space mission. Students will learn about the numerous systems, skills and capabilities involved in a mission and how NASA manages and integrates these systems. Students will draw a parallel between the teamwork used in a NASA mission and find out how teamwork energizes the popular sport of auto racing. Grades 6-8.
Historical Introduction to Philosophy
This course covers the following topics: an introduction to philosophy; philosophy of religion; epistemology; the philosophy of mind; free-will and determinism; ethics and metaphysics.
Linear Systems and Optimization: Introduction to Linear Dynamical Systems
Introduction to applied linear algebra and linear dynamical systems, with applications to circuits, signal processing, communications, and control systems. Topics include: Least-squares aproximations of over-determined equations and least-norm solutions of underdetermined equations. Symmetric matrices, matrix norm and singular value decomposition. Eigenvalues, left and right eigenvectors, and dynamical interpretation. Matrix exponential, stability, and asymptotic behavior. Multi-input multi-outp
Discovering Information Systems An Exploratory Approach
Note: This book was written in 1999 and last updated in 2003. Since then technologies have changed so the non-conceptual and more technical parts of the book may be out of date. Why Yet Another Textbook (WYAT)? There are many excellent introductory information systems (IS) texts on the market. Why then produce our own text? Interestingly enough, when we sat down to critically review the first year Information Systems curriculum, the very last thing that we wanted was to get involved in writing
Introduction to Molecular Virology
Introductory Virology for 2nd and 3rd year courses The material consists of a series of linked pages exploring an introduction to the concept of viruses, and an exploration of their general properties. This site provides the basis of material for 7-lecture course in introductory microbiology (MCB2016F) and a 20-lecture course (MCB3024S, Defence and Disease) given to third-year students.
This animation represents the case of frictionless motion of an object that experiences a centripetal force. More specifically, the strength of the centripetal force is proportional to the distance to the central axis of rotation. A proportional centripetal force is very symmetrical and the motion under the influence of that force has distinctive properties.
