1900 Air Pollution
Rating

This article and included graphs,from the web site accompanying the FRONTLINE NOVA special What's Up with the Weather?, reveals how atmospheric carbon dioxide, methane, and nitrous oxides from coal- and oil-burning power plants, cars, and other fossil-fuel-burning sources have climbed along with the world population, with as yet unknown effects on the climate system.

Black Magic

Most non-permanent markers use inks that are made of mixtures of colored pigments and water. How does Black Magic work? Why do some black inks separate into many colors on a wet coffee filter? Why does mixing many colors of ink make black?

Chemical Elements: An Online Interactive Periodic Table
Rating

This is an online interactive periodic table of the elements which includes all elements up to 118. There are several different options for viewing, such as date of discovery, electron configuration, number of neutrons, etc. Elements can also be viewed by element groups. Additional links to further information on a particular element are given in some cases. Citation information is also provided.

Common Sense Concepts of Motion
Rating

Common sense (CS) misconceptions are not arbitrary or trivial. Indeed, every one of the misconceptions about motion common among students today was seriously advocated by leading intellectuals in pre-Newtonian times. If the evaluation of CS was so difficult for the intellectual giants from Aristotle to Galileo, we should not be surprised it is a problem for ordinary students today. Accordingly, common sense beliefs should be treated with genuine respect by instructors and regarded as serious alternative hypotheses to be evaluated by scientific procedures. A taxonomy of common sense concepts which conflict with Newton s laws is presented. Elementary teachers who are aware of these CS beliefs can teach deliberately to avoid contributing to student development of misconceptions.

Coriolis Effect
Rating

This animation provides a practical example of the impact of the Coriolis effect on daily life. After examining the animation, students can use a map or globe to locate where the pilots might have landed if they had followed their original flight path. They can then estimate how many miles the pilots have gone off their course. Students can also think about factors that navigators would consider when planning their flights and research the calculations used to account for the Coriolis effect. Although the resource was designed to accompany a specific Earth science textbook, it can be used without that text.

Diffusion and Osmosis
Rating

This web based instructional material is part of HyperPhysics. HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network. The bottom bar of each card contains links to major concept maps for divisions of physics, plus a "go back" feature to allow you to retrace the path of an exploration. The side bar contains a link to the extensive Index, which itself is composed of active links. That sidebar also contains links to relevant concept maps. The rationale for such concept maps is to provide a visual survey of conceptually connected material, and it is hoped that they will provide some answers to the question "where do I go from here?". Whether you need further explanation of concepts which underly the current card content, or are seeking applications which go beyond it, the concept map may help you find the desired information. Part of the intent for this exploration environment is to provide many opportunities for numerical exploration in the form of active formuli and standard problems implemented in Javascript. An active exploration in physics will typically lead you to something which needs to be quantified, and it is hoped that the many Javascript-enabled calculations will provide many opportunities to answer "What if .." type questions.
