CSU Engine Web Pages
This resource on internal combustion engines comes from a mechanical engineering professor at Colorado State University. It is essentially an online textbook with three main chapters, which cover the topics of thermodynamics, heat transfer, and fluid mechanics involved in engine operation. Users should have an understanding of basic engine components, and a background in calculus would be helpful. Some of the material is fairly conceptual, while other parts involve analytical derivations. Many s

Since its inception over a half century ago, the Soil Association has "been working to raise awareness about the positive health and environmental benefits of organic food and farming and supporting farmers in producing natural food consumers can trust." Originally formed by a coalition of inspired scientists, nutritionists, and farmers, the Soil Association is now the leading organic farming and food certification and campaigning organization in the United Kingdom. Although primarily geared tow
The Messier Catalog
The Students for the Exploration and Development of Space of the University of Arizona maintains The Messier Catalog Web site. Named after the French astronomer who first discovered the objects, the catalog describes and features what are considered to be some of the most beautiful nebulae, star clusters, and galaxies in the sky. Visitors can read about Messier and about each individual object in the actual catalog, which includes a picture, its distance, brightness, the history of its discovery
Dialogue for Kids Wild About Bears Sleepy Bear Lesson Plan
Each winter, bears hunker down, slow their metabolisms, and pretty much wait out the winter in the safety of some sort of den. This lesson plan, from Idaho Public Television, is a fun way to illustrate to children (probably elementary grades primarily) the process of hibernation. At this site, educators are given the complete lesson plan instructions as well as several links to all sorts of great resources, including links to information on: Bear Diet, Home Range, Reproduction, Bear Research, Pe
An educational lesson plan entitled Water is offered by the Seaworld teacher resources Web site. Objectives of the unit include having students identify the three phases of water, discuss the hydrologic cycle, describe the structure of the water molecule and the properties of water, explain ocean currents, and more. The well designed lesson allows students to study various topics by reading provided text and completing the activities described such as measuring salt content in water and estimati
Highlight of Biochemistry: Molecular Structures Made Visible
This Web site from the University of Hamburg Faculty of Biology offers useful three-dimensional images of molecular structures, many of them animated. The dozens of images included in this site should help visual learners understand molecular structure and function in a number of contexts, including virology, immunology, neurology, photosynthesis, genetics, and more. Detailed descriptions and related information accompany each image. This Web site also provides links to three tutorials covering
Insecta Inspecta World
Insecta Inspecta is the result of an interdisciplinary program at Thornton Jr. High School under the review of the Smithsonian's National Museum of Natural History. This Web site offers a fun way to learn about insects and other arthropods, and does a great job of placing these bugs in a larger cultural and historical context. In addition to providing a solid introduction to insects and arthropods, this site includes quirky trivia and entertaining audio and movie clips. For instance, visitors ca
Bing & Bong's Tiny Planet
The Bing & Bong's Tiny Planet website, a supplement to the educational television series, offers excellent science activities, games, and online books for small children. Users can sail around the planet to learn about wind, read an online story to discover space, take an adventure through the water cycle, and much more. Visitors can also learn the essentials of colors, shapes, and light through short videos and interactive modules. The colorful website offers a great way for children to begin l
The NBN Gateway
Several British conservation and natural resource organizations have collaborated to form the National Biodiversity Network (NBN), a network of biodiversity data. After the free registration, users can access the NBN gateway, which hosts a large variety of datasets that can be navigated by species name or site location. Results allow users to view 10km distribution maps of the selected species. This site encompasses a large amount of data on species distribution in Britain; however, some of the
Air pollution is a growing problem today. This lesson plan is designed to teach students about the problem, its effects on our environment and health and the latest methods designed to combat air pollution. The objectives of this lesson are (1) to define air pollution, (2) to identify major causes of air pollution (e.g., automobiles, burning garbage, electric power plants emissions, industrial boilers and certain consumer products), (3) to identify the effects of air pollution (health effects in
Teacher's guide to the infrared
This is a page from a larger website, Seeing our World Through a Different Light, sponsored in part by NASA. This page contains side by side standard and IR photos to illustrate how IR photos show heat. It describes and compares visible light and infrared light. An explanation, accompanied by photos, of how infrared cameras work is also provided.
Keeping Cool at Deep-Sea Vents
This Astrobiology Magazine article reports that a research team of marine scientists has determined that water chemistry controls the location and distribution of two species of weird worms inhabiting deep-sea hydrothermal vent sites: the tubeworm (Riftia pachyptila) and Pompeii worm (Alvinella pompejana). The article includes color images of the worms and monitoring equipment, links to related web pages and other astrobiology resources, and an MP3 machine text-to-speech function.
The race of microorganisms
This reading, part of a site devoted to the science of cooking, explores how beneficial bacteria are involved in the fermentation process that is used to pickle vegetables. The reading focuses on the competition between those microorganisms that facilitate fermentation and those microbes that damage this food production process. Lactic acid bacteria are key players in the creation of pickles. The reading explains the functions of these bacteria and describes the conditions in a pickle crock--inc
Earth and Space
In earth and space science, students study the origin, structure, and physical phenomena of the earth and the universe. Earth and space science studies include concepts in geology, meteorology, oceanography, and astronomy.
2.14 Summing up
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
Don't Crack Humpty
Student groups are provided with a generic car base. The groups then design a device/enclosure that will protect an egg on or in the car as it is rolled down a ramp at increasing slopes. Students will be expected to perform basic mathematical calculations using their data.
5.1 The essays in context
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
Which Roof is Tops?
When you walk or drive around your neighborhood what do the roofs look like? What if you lived in an area with a different climate, how would that effect the style of roof that you might find. This is an introductory activity to explore the advantages of different roof shapes for different climates or situations.
Wellesley index to Victorian periodicals 1824-1900
The Wellesley Index to Victorian Periodicals, 1824-1900, is a subscription bibliographic database of articles in nineteenth-century periodicals. It primary use is to identify authorship. It was common during the Victorian era for articles by periodical contributors to be published anonymously, or under a pseudonym. The great achievement of the Wellesley Index was to provide provenance details and evidence to support attributions of authorship, along with brief biographical and vocation details o
