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.

The representation depicts an object moving along a "track" marked in .5 meter intervals. As the object moves, displacement-time, velocity-time, and acceleration-time graphs record the motion in real time. The user may select various types of motion to be depicted, as well as edit a velocity-time graph and have the resulting motion depicted. As the object moves, color coded vectors display its displacement, velocity and acceleration. Less

This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050. Less

Students understand how satellites are placed in orbit by launching marbles into space, using two plastic rulers and clay. They describe the forces that determine the trajectory of flight. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Phenomenal Weather. Lesson objectives supported by the video, additional resources, teaching tips and an answer sheet are included in the teacher's guide. Less

In this physics activity, learners build their own rockets out of film canisters and construction paper. Learners discover how a chemical reaction (from a mix of water and Alka-Seltzer) creates gas pressure to propel the craft. The activity explores the three states of matter and Newtonäóťs Laws of Motion. Less

In this activity, learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit. Learners use play-dough and keys to design their own molecular models that demonstrate how shapes of molecules are important to self-assembly. <br> <br> Note: The write-up for this activity starts on the bottom of page 12. <br> Less

In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit. By fitting their hands into uniquely-shaped Play-dough models, learners simulate how receptors recognize each other and stick together based on their distinctive three-dimensional forms. This activity includes an optional extension, in which learners match objects to impressions of the objects in play-dough. Use this activity to introduce concepts related to nanotechnology, self-assembly, antigens, and antibodies. Less

586 Million Year Cycle in Geology Matches Galactic Super-Cluster Spacings

The longest geological cycle identified is described as about 600 million years ... More

The longest geological cycle identified is described as about 600 million years in "Megacycles", the proceedings of a geological conference, Edited by G Williams. However Prof. S. Afanasiev of Moscow has determined the cycle very accurately to be 586.24 million years using his Nanocycles Method. It so happens that cosmologists, Broadhurst, T.J., Ellis, R.S., Koo, D.C. & Szalay (Nature 343, p 726) have observed regular mega-walls of galaxies at spacings that they describe as 128 Mpc/h, which based on the latest Hubble constant values would correspond to 588 million light years. Some cosmologists have suggested that the regularity might result from standing waves. Standing waves in space of wavelength 586 million light years would oscillate in 586 million years. In addition, if there are present harmonics of these waves as both the geological cycles and the additional peaks in the galaxy survey indicate, then powerfully energetic events would recur on Earth at these intervals. This agreement on the wave sizes actually allows a much more accurate Hubble constant to be determined from Afanasiev's accurate cycle period. Less
