Modern and Fossil Pollen Data
Palynology research scientists from around the world contribute pollen data to the NOAA Paleoclimatology World Data Center (WDC). There are pollen counts, related information, and various derived data sets. Users can access or contribute data. There are several links on obtaining WDC data, other data archives, software (including Tilia and PALYHELP), and other paleoclimatology, climatology, and botany sites.
The US stock market crash of 1929 set off the most severe economic depression in the Western world. The so-called Great Depression lasted more than a decade, until approximately 1941. In the United States, the general atmosphere was one of desolation, as expressed in the Dorothea Lange photograph "Thirteen Million Unemployed Fill the City in the Early Thirties," which shows men leaning against a wall in San Francisco. Many photographs in this topic were taken by Lange, one of the primary chronic

In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas produced from a chemical reaction between an antacid tablet and water to propel it. Students observe the effect that surface area of this simulated solid rocket fuel has on thrust.
World History Survey Course on the Web
World History teachers face many challenges to incorporating primary sources in their teaching—the pressures of coverage in survey courses, the lack of available materials, and inadequate training in dealing with unfamiliar sources from a range of cultures. World History Sources responds to these challenges (as well as the new opportunities offered by the Internet) by creating a website to help world history teachers and students locate, analyze, and learn from online primary sources and to fu
Access to the Internet
Using the Internet depends, in the first instance, on access to the network. The initial emergence of "the Internet" in the early 1990s, from the increasing connectivity of a series of university and government networks alongside private services like America Online, Prodigy, and CompuServe, occurred almost entirely across slow dial-up modem connections over telephone wires. Sufficient for email, Usenet news groups, transferring relatively small files, and later viewing simple web pages, slow tr
This brochure looks at how genes work, exceptions to Mendel's rules, how DNA gets replicated, genes and disease, current research and recent discoveries, and how applications of genetic research (biotechnology) are being used in agriculture, health, and pharmacogenetics (medicine) to change our world for the better.
Pio Pico Researchers Participatory Action Research: From Classroom to Community, Transforming Teachi
Emily Wolk is a teacher of a group of students, aged 8-11 years old, called the Pio Pico Researchers.

Picking up, examining and collecting rocks can be the first steps in moving children toward an appreciation of geology and the “bones” of the Earth. Children can find a wide variety of rocks in many places, from the school yard to parks and driveways at home. Even very young children enjoy picking up rocks, lining them up, choosing “favorite” ones, pouring water over them to make them shiny and even painting them as gifts for adults. By letting children handle and observe rocks you give

Now bankers’ bonuses are back, house prices are rising again and politicians promise recovery while unemployment remains high, debts mount, frictions with China grow and the planet overheats.

Atheists On Religion.
For the last 150 years or so European philosophers and sociologists have tended to regard religion as just one more pre-scientific myth and superstition that has had its day, and likely to wither on the vine of History. This view, the secularization thesis, seems today to be in poor shape.

Classic atheist criticisms of religion tend today to sound
