NASA KSNN Why do magnets work?
Magnetism is an invisible force felt within the space around a magnet. This space, called the magnetic field, can either attract (pull) or repel (push away) other magnets and some types of metal
Wetlands of the coastal plains
This Carolina Environmental Diversity Explorations "virtual field trip" explores the various wetlands of North Carolina's coastal plain, including the longleaf pine savanna, sandhill scrub, pocosin, pond pine woodland, coastal plain bottomland forest, tidal freshwater marsh, cypress gum swamp, and salt marsh. In each type of wetland, you'll learn about the various plant communities and their adaptations to their environment. You'll also learn how wetlands are formed and why North Carolina has so
Cell Differentials offers a visual dataset of white blood cells that gives students practice in developing strategies and techniques for the recognition of these blood cell types. Over 100 different cell images are randomly presented with feedback on successful identification. In traditional labs, the recognition of white blood cell types can be compromised by several factors. Developmental changes can make recognition difficult and some cell types exhibit similar features. Microscopy can be a
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
BeeVisit enables students to evaluate the relative contributions of different pollinator species to a plant's reproductive success through an interactive model of pollen transfer. The model tracks a plant's presentation of pollen through time; pollen may be presented gradually or all at once, and the program lets you choose from a family of power curves to model the shape of the cumulative pollen presentation curve over a set number of time intervals (usually 100). Then, 'bees' of 1, 2, or 3 ty
A Deeper Look Into Seeds
Developed for second grade. Students will: use their sense of touch and sight to discover differences between several types of seeds; discuss why seeds come in different shapes and sizes; make connections between art and science; discuss the growth process of a seed; discuss how different seeds are used in different products. Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a colleg
The Structure and Interpretation of Computer Programs
This is an introduction to programming and computer science. This course exposes students to techniques of abstraction at several levels: (a) within a programming language, using higher-order functions, manifest types, data-directed programming, and message-passing; (b) between programming languages, using functional and rule-based languages as examples. It also relates these techniques to the practical problems of implementation of languages and algorithms on a von Neumann machine. There are se
This course familiarizes students with Macromedia Flash. Topics to be covered include fundamental programming concepts (variables, variable types, code re-use, commenting code, and basic control structures) in addition to the fundamentals of the flash environment (animation, vector graphics, use of sound and video). Students finishing this course will have at least one completed fully functional Flash project for their portfolios demonstrating a strong knowledge of the tool and a good foundation
National Water Information System Web Data for the Nation
This USGS site provides access to water resources data collected at approximately 1.5 million sites in all 50 states, the District of Columbia, and Puerto Rico. The site features real-time and historical data retrievable by geographic area for surface water, groundwater, and water quality conditions such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds. The site also includes an extensive inventory of information about data collection sites at strea
Descriptive Model of Au-Ag-Te Veins
This USGS document provides a summary of characteristics of gold-silver-tellurium vein deposits. The data includes the geological environment of the deposits such as rock types, textures, age ranges, depositional environment, tectonic setting, and associated deposit types. The deposit description includes information about mineralogy, texture/structure, alteration, ore controls, and weathering. Also included is a list of examples where these vein deposits are found.
This description of a ground-water aquifer has a graphic representation to accompany it. It is part of the U.S. Geologic Survey's Water Science for Schools website. Links to other parts of the site, such as definitions and types of wells, are included.
Principle Types of Volcanoes
This page presents information about the four principle types of volcanoes found on Earth. Diagrams showing the internal structure of each type and photographs of well-known examples are provided.
Emerging Enterprise Consulting (Syracuse University)
Entrepreneurship is the key to the American dream. Sustainable growth and an enhanced standard of living for all Americans are dependent on a vibrant, growing entrepreneurial sector. There is a need for entrepreneurs with creative business concepts and the courage to turn these concepts into sustainable enterprises that create jobs for citizens and create value for customers. There is a key difference, however, between starting a business and growing one. The majority of small businesses fail to
Entrepreneurship is the "pursuit of opportunity without regard to resources currently controlled". This definition implies that successful entrepreneurs are able to utilize resources that they do not personally own or control. They must go beyond opportunity recognition and the creation of great business concepts and find creative methods for acquiring a variety of resources. Especially critical is their ability to find money for venture start-up and then to obtain money for ongoing venture grow
Beneficial Bug Scavenger Hunt
Students learn to identify several beneficial insects and spiders, including predators and pollinators, then record numbers and types of beneficial insects and spiders that they discover in the outdoors, and discuss ways that the insects and spiders that they observed are adapted to be pollinators or predators.
LAYOFF uses a simple casual game paradigm to comment on the current state of the US financial crisis. Both friends and strangers face tough times in an unstable economy. Part dark humor, part grim portent, in the game players play from the side of management needing to cut jobs, and match types of workers in groups in order to lay the workers off and increase workforce efficiency.
