Discovery may jump-start mine remediation efforts
This article from November 30, 2000 describes how bacteria contribute to detoxify ground water by chemically altering lead and zinc compounds resulting in useful mineral deposits. It underscores the relationships between the hydrosphere, lithosphere, and biosphere and points to bioremediation processes useful in controlling contaminations associated with mining.

Shape explorer
This Java applet is designed to allow students to practice visualizing and calculating area and perimeter for figures formed by adjacent squares on a grid. After the student selects a size using a slide bar, the Java applet generates a random closed figure. The student enters values for the figure's area and perimeter, which are checked automatically. The applet limits figures to rectangles and generates two column comparisons of areas and perimeters for multiple figures. From the activity page,

How do you light up your bike without reflectors or lamps?
Bicycle safety is a critical matter. This riddle asks students how they can illuminate their bicycles without using reflectors or headlamps. Before they select their answer, students are given a clue. They read about and watch a video clip of two children's attempts to use glow-in-the-dark materials to light up their bikes. The riddle's final page presents students with three clickable answer choices. Brief feedback is given for the incorrect choices. When students select the best answer, a shor

Solar heating and cooling
This reading from a site about the future of energy introduces students to passive solar design for homes. The reading describes design elements that are used for passive solar heating and cooling. For example, reflective coatings can be applied to roofs, windows, and exterior walls to help cool houses. The reading recommends that those interested in passive solar design consult an architect.

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.

Science Sampler : Rockin' around the rock cycle
The following inquiry-based activities were designed as part of a unit intended to aid students in understanding the rock cycle, with the assumption that, after being taught the lessons in the unit, students would have gone beyond a rote memorization of the rock types and rock cycle. The ultimate goal of this hands-on lesson is that students will know and be able to discriminate between them.
