Access Excellence: Louis Pasteur (1822-1895)
Part of the Resource Center from the National Health Museum, this one-page Louis Pasteur biography includes a link to a page describing how Pasteur debunked spontaneous generation. "For example, a seventeenth century recipe for the spontaneous production of mice required placing sweaty underwear and husks of wheat in an open-mouthed jar, then waiting for about 21 days, during which time it was alleged that the sweat from the underwear would penetrate the husks of wheat, changing them into mice."

All About Snow
"Is it ever too cold to snow? How big can snowflakes get? Why is snow white?" Everything you ever wanted to know about snow (but didn't know who to ask) is answered here by the National Snow and Ice Data Center, affiliated with the University of Colorado. This educational site also includes a Snow Glossary (from "ablation" to "vapor pressure"), a Snow Fact Sheet and a feature on the history of snow removal. The first known snow plow was pulled by horses through the "snow-clogged streets" of Milwaukee in 1862.

American Association for the Advancement of Science
The American Association for the Advancement of Science (AAAS, pronounced "Triple-A-S") is the world's largest general science organization and publisher of the peer-reviewed journal Science.

Roger Evans, an Iowa Meterologist, has developed this activity for students in grades 7 to 12.
A teacher's guide is included.
Building Big
Budding engineers and architects will flip over this interactive exploration of big bridges, big dams, big domes, big tunnels and skyscrapers (which, by definition, are all big.) Get virtual hands-on experience with the Labs (learn about forces and materials) and Challenges (design a structure.) Other great clicks are the searchable Wonders of the World data bank with a form for submitting your own local wonders, and the activities and experiments found in the Educators' Guide.

Caltech: Snowflakes and Snow Crystals
"This site is all about snow crystals and snowflakes -- what they are, where they come from, and just how these remarkably complex and beautiful structures are created, quite literally, out of thin air." Best place to start on this Caltech site is the Snowflake Primer, where you'll learn the answer to questions such as "Is it really true that no two snow crystals are alike?" and "Why do snow crystals form in such complex symmetrical shapes?"

Center for Environmental Research
CSE brings together the talents and expertise of scientists, educators, independent scholars, business leaders, government agencies, non-profits, students, and community members to seek creative solutions to environmental problems. These challenges are addressed through initiatives that safeguard natural and cultural values and resources. By combining technical innovations with the knowledge, values, and practices of local communities, we generate long-term environmental solutions that enhance the lives of those they impact.
A Coastal Journey
Coastal Journey is a diary of scientific discovery written by a young teen, as she explores the rocky shores of Washington state
with her marine biologist father. She writes about the tides, the difficult living conditions they create, and five kinds of plants and animals that live in tide pools: algae, cnidarians, crustaceans, echinoderms, and mollusks.  The diary is nicely illustrated with photographs and drawings, but lacks a table of contents.
Composting for Kids
"Composting is fun! It's also easy. Let's learn about how we make compost and how we use it to grow beautiful gardens." Learning how to compost was one of the very first tasks I took on when we moved into our big-yard house. Not only is it satisfying to create our own nutritious mulch for the vegetables and flowers, but it is also ecologically and economically sound. Kids (and parents) can learn how in this simple slide presentation.
Convert Me
Convert Me has "interactive calculators for many measurement systems both commonly used like metric and U.S. Avoirdupois and quite exotic like Ancient Greek and Roman." These calculators allow you to specify significant figures (which determines how much rounding is done), a feature not found on other sites. To use, first select the type of unit such as Weight and Mass, or Distance and Length. Enter the measurement you want to convert from (such as 1.5 pounds) and click Convert. You'll get the conversion in all available units, such as .68 kilograms, 18 Chinese taels and 53 old Russian lots.
Create Your Own Web Page
Creating pages for the World Wide Web takes a little practice, but once you get the hang of it, it's a lot of fun. The first step is to decide what you want to publish in your Web page.Maybe you want to publish a story you've written, or share reviews of books you've read, or create an electronic magazine related to one of your hobbies... Whatever you want to put in your Web page, the directions in this step-by-step guide will show you how to do it.
CyberSleuth Kids: Units of Measurement Worksheets
These twenty-three printable worksheets for elementary ages provide practice for converting units of length (mostly) and units of weight (just a few.) The worksheets are not labeled, so you will need to click on each image to see what it covers. Topics include millimeters to centimeters, inches to feet, feet to yards, ounces to pounds, and vice versa. To print the pages without headers and footers, remove them in your browser's Page Setup dialog.
Damien's Skyscraper Page
Damien is a Australian skyscraper enthusiast, and an excellent illustrator. Visit his site to marvel at his skyscraper renderings, which you'll find listed under Contents. Must clicks include Larger and More Detailed Diagrams of Skyscrapers (Parts One, Two, Three and Four), Diagrams of Buildings (which click through to fact sheets with photos), and Diagram Comparing Tall Buildings to Other Tall Structures. Okay, so the titles aren't that catchy, but the detail in his work is awesome.

Earth and Sky: Skywatching
Ever wish you had an experienced astronomer standing by your side to guide you to the nightly show? Now you do. Meet Deborah Byrd, Skywatching columnist. "Each day's segment is designed to guide your eye to something you can see that night, or the next morning before dawn. It might be a constellation, a star, or a planet. Or it might be a celestial event, such as an eclipse." In addition to this feature, teachers and lower-elementary kids have their own sections, accessible from the lunar menu at the top of each page.
EdHelper: Measurement Worksheets
Despite the title, this EdHelper page is not just worksheets, but a collection of puzzles, word stories, charts and lesson plans, all related to units of measurement. English length, weight, capacity, time and temperature are covered on this table of contents. Metric units are covered on a separate page (look for the Also Visit link.) Some of the worksheet links only provide a single printable worksheet, while others allow you to generate an unlimited number of handouts and answer keys. Although paying members get even more worksheets, there is enough free content to earn a five-star rating.

Education for Geo-Hazards: Lighting Strike!
"When you first see lightning or hear thunder, activate your emergency plan. Now is the time to go to a building or a vehicle. IF OUTDOORS ... Avoid water, high ground & open spaces & all metal objects including electric wires." Lightning is just one of the geo-hazards addressed in this safety site for kids. Be sure to practice the lightning crouch, it is the safest way to "hide" if you are stuck outside and can not find shelter. In addition to the multimedia site, you can download the hazard preparedness book in PDF.

Enchanted Learning: The Intertidal Zone
The colorful Enchanted Learning site for elementary ages features a nice illustration of the four intertidal zones: from the spray zone (which is usually dry) to the low tide zone (which is almost always wet.)  But the best clicks are the twenty printable, color-able animal printouts arranged in alphabetic order from anemone to zooplankton. There are related sections on Tides (follow the hyperlink in the opening text), Walruses, and Biomes.
EPA: Drinking Water Kids Stuff
The EPA offers a combination of online lessons, games, and three printable curriculum guides for grades K through 12. Make "Games and Online Activities" your first stop, where (despite the title) you'll find educational, illustrated articles on the water cycle, water treatment, conservation tips, water trivia and two word games. For fun projects for home, scout troop, or classroom (such as "Build Your Own Water Cycle" and "Build Your Own Watershed.") visit "Classroom Activities & Experiments."

Corporate and other sponsors have contributed funding for the development of EurekAlert!, a comprehensive Web site about the latest research advances in science, medicine, health, and technology.
FamilyFun: Gardening Projects
These six fun craft projects take gardening one step further. For example, craft number two is a sock mouse for your cat with catnip you've grown yourself. My favorite is a practical joke done with a pickle. "The object here is to astound your friends with a little horticultural sleight of hand. They'll be in a pickle wondering how you managed to squeeze that great big vegetable through that skinny little bottleneck." Click through to page six to learn more.
This Annenberg Project presentation will help students realize how much waste actually accumulates on Earth from daily living. They'll learn, for example, that they create four pounds of garbage every day!

How Stuff Works: Pasteur's Experiment
In their article on the scientific method, How Stuff Works uses one of Pasteur's famous spontaneous generation experiment as an example. It describes step-by-step how Pasteur Pasteur proved that germs could only come from other germs, and could not be generated spontaneously. "Pasteur's experiment has all of the hallmarks of modern scientific inquiry. It begins with a hypothesis and it tests that hypothesis using a carefully controlled experiment. This same process -- based on the same logical sequence of steps -- has been employed by scientists for nearly 150 years."

Imaginary Lines
Imaginary Lines was founded by former astronaut Sally Ride - America's first woman in space - to provide support for all the girls who are, or might become, interested in science, math and technology.

The Kitchen: What is Pasteurization?
Although Louis Pasteur is not referenced by name, this one-page article from The Kitchn does a nice job of explaining how milk is pasteurized and why. "The process of heating milk to kill pathogens and prevent spoilage was developed back in the 1860's, but it didn't become standard until dairy farming became industrialized in the 1900's. As milk started being collected and distributed by centralized companies, the risk of contamination grew and pasteurization became a necessity."

Tide predictions from around the globe.
The best time to view the many creatures that live along a rocky shore is during low tide, when pools of water and animals become trapped in the rocks.  When climbing along the tide pools, take care not to harm any of the residents. And if you pick something up, return it gently where you found it.  To find the tide schedule for your area, check your newspaper or try Tides Info.

Just give us a few minutes, and we'll show you the step-by-step basics to get you started on writing Web pages and understanding the basics of the Internet.
Web Site Criteria
The Web is a lot like a flea market: there's a vast selection of sites to choose from but not a lot of order to it. Some sites are offered by reputable "dealers" and some from individuals who want to show off their personal favorite items. Sometimes it's hard to tell what's a hidden treasure, what's worth taking a look at, and what's a waste of time.
World Trade Center History
The twin towers of the World Trade Center were more than just buildings. They were proof of New York's belief in itself. Built at a time when New York's future was cloudy, the towers restored confidence and stopped the decline of lower Manhattan. Brash, glitzy, and grand, they quickly became symbols of New York. But the idea wasn't universally liked. Critics argued that the skyscrapers would ruin New York's skyline and strain city services. With support from David Rockefeller (chairman of Chase Manhattan bank) and his brother Nelson (governor of New York) the project was approved and construction began in 1965.
