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
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.
5.1.3 Keeping Microsoft up-to-date
Frightened of the internet? This unit will help you make effective use of the internet, giving you the basic skills required for using web-based resources. Useful tricks and tips are provided as well as information on web browsers, the main features of a browser window, how to look at websites, using hyperlinks, searching for information on the internet, copying text, avoiding computer viruses, and using PDFs.

Cell Phone Spectrophotometer
Instructions and software are provided to allow students to build an inexpensive spectrophotometer, using digital cameras or cell phone cameras as array detectors. Supplementary materials include instructions for high school teachers and laboratory instructions for both high school and college students. Software source code allows customization.
Experiments in Electroanalytical Chemistry
This website offers educators a set of eight classical electroanalytical experiments suitable for use in a quantitative analysis, instrumental analysis, or electrochemistry course. The materials should be useful for advanced undergraduates and beginning graduate students. Experiments include coulometric, conductometric, and potentiometric titrations, stripping analysis, flow injection analysis, and polarography. It is important to note that several of the experiments use mercury or mercury co
