Science Sampler : Weathering database technology
Collecting weather data is a traditional part of a meteorology unit at the middle level, but making connections between the data and weather conditions can be a challenge for students. One way to help students make these connections clearer is to enter the data into a database. This allows students to quickly compare different fields of data and recognize which readings are associated with certain types of weather.

Similarity
In this workshop session, elementary and middle school teachers explore scale drawing, similar triangles, and trigonometry in terms of ratios and proportion. Besides explanations and real-world problems, the unit includes video segments that show teachers investigating problems of similarity. To understand the ratios that underlie trigonometry, participants use an interactive activity provided online. This is session 8 of Learning Math: Geometry, a free online course.

Examine the sun at different wavelengths
This Earth science resource enables students to observe and compare the sun's appearance under different types of electromagnetic radiation. Students are instructed to move the cursor across the spectrum to see images of the sun under radio and microwaves; infrared, visible, and ultraviolet light; and gamma rays. Each image includes a label that indicates the portion of the electromagnetic spectrum, the wavelength in angstroms and meters, and the layer of the sun in view. Copyright 2005 Eisenhow

Quick take on math starters
If you want to hook your class on math right from the start, you may want to consider one of these real-world projects. Students deal with real data in these investigations collecting, presenting, and analyzing their findings. As they work on the NCTM Data Analysis and Probability Standard, they apply school mathematics in contexts arising outside of mathematics, as recommended in the Connections Standard.

National Geophysical Data Center: Relief Globe Slides
This set of 20 slides contains 14 global views of the Earth in full color shaded relief, showing land and undersea topography. The planet is seen from vantage points over the poles and each major ocean and land mass. Also included are a rectangular Mercator projection view of the whole Earth, as well as displays of crustal plates and their relation to world seismic activity. The images are computer-generated from a digital database of oceanic bathymetry and land topography.

Sunlight and the Earth : Climate and Weather
These web pages trace the processes involved in the suns impact on weather. This is an exploration of the importance of radiation and reflection of light, both visible and infra-red, and the greenhouse effect. Convection and the role of water vapor are also considered. Global-scale air flows are described, explaining why wind in the continental US usually blows from the west, while near the equator it comes from the east.

Quick take on action with fractions
Really understanding what fractions are, how they fit on the number line, and how to operate with them-add, subtract, multiply, divide-is central to learning decimals and percentages. According to the NCTM Principles and Standards, students in the middle grades should be expected to acquire a deeper understanding of fractions, decimals, and percents and an increased flexibility in using them to solve problems. Yet students may reach even the higher grades of middle school without a firm grasp of
