Lunar Plant Growth Chamber
This site invites students to design chambers for growing plants on the moon. (Plants may be used to supplement meals of astronauts during space exploration.) Teacher guides include lessons on providing light and water for the plants, choosing plant species, exploring the moon, and designing, building, and evaluating plant growth chambers.
Earth Explorers Series
Who Are NASA's Earth Explorers? The elementary school student questioning if El Nino occurs anywhere besides the Pacific Ocean... The researcher investigating connections between Arctic ozone depletion and global climate change... The consumer comparing hydrocarbon versus hydrogen-powered cars... And the business person projecting future needs for harvest, delivery, and storage of crops... All of these people are Earth Explorers -- they are all connected by their curiosity about Earth system pro
Chandra X-ray Observatory
features news and information about NASA's newest space telescope. As the world's most powerful X-rayobservatory, Chandra joins the Hubble Space Telescope and NASA's other observatories in a study of our universe, providing insights into the universe's structure and evolution. Visitors can track Chandra in orbit, watch live images from NASA-TV, and learn more about prior shuttle launch preparations.
Amazing Space consists of web-based educational presentations for young children about space, which were developed at the Space Telescope Science and Technology Institute. Teachers teamed up with scientists and engineers from the institute and staff members from the Office of Public Outreach to develop interactive lessons. All lessons include spectacular photographs taken by the Hubble Space Telescope and many high quality graphics, videos, and animation designed to enhance student understanding
3... 2... 1... Liftoff! Educator Guide
Introduces children to the International Space Station (ISS), the most complex international scientific endeavor in history. Activities focus on the purpose and construction of the ISS, the history of rockets, and the role of rockets in space station assembly. Activities emphasize hands-on involvement, data collection, observation, exploration, prediction, interpretation, problem solving, and language skills.
21st Century Explorer
This site answers questions that include: Why do we want to travel to Mars? How would your body change in space? Where would a space explorer find water and oxygen? How can we travel faster in space? Student actors (on video) and hands-on activities are featured with each answer. The site is for Grades 3-5 and available in Spanish.
The EJS Beats model displays the result of adding two waves with different frequencies. The simulation displays the superposition of the two waves as well as a phasor diagram that shows how the waves add up at one point in space. The ratio of the wave amplitudes, the ratio of the frequencies, and the phase shift between the two waves can be changed via textboxes.
Introductory Tutorial to Mass Spectrometry
An introduction to GC-MS for beginning students in analytical or organic chemistry lab. The site includes discussion of quadrupole mass analyzers, ionization, detection, and interpretation of mass spectra. One of the best features of this site is a series of on-line quizzes on the interpretation of EI mass spectra that includes hints as well as explanations of why the answers are right or wrong.
Space coupe to the rescue
For this online activity, students raise and lower their Space Coupe to line it up and destroy virus pods using positive or negative numbers. The challenge is to destroy all eight virus pods within a given time. Negative numbers take the Coupe in a downward direction, sometimes below the waterline, while positive numbers take the Coupe in an upward direction, including out of the water and into the air. The distance the ship needs to travel to destroy each pod is counted using a scale on the lef
Middle School Portal: Math and Science Pathways (MSP2)
In this online activity, students are challenged to reproduce 20 different figures using the seven pieces of the Chinese tangram game. The figure to be reproduced is shown in the upper right corner of the screen. The student points and clicks to rotate and position the tangram pieces to copy the figure. For each figure, the student must use, but not overlap, all seven pieces. Clicking on the hint will put outlines of the tangram pieces on the figure the student is trying to reproduce. Figures in
Tournaments : I've got to win how many games?
In this activity, students are challenged to determine how many more basketball games were played in a tournament with a field of 64 teams, compared to a field of 32 teams. Part of the Figure This! collection of 80 math challenges, this exploration challenges students to use a variety of problem-solving techniques that include developing equations, making tables, and drawing tournament brackets. The importance of these strategies in making business decisions and planning space missions is noted.
The Adventures of Josie True
The Adventures of Josie True is a web-based historical adventure game for girls. The hero of the game is Chinese-American Josie True, a regular girl who becomes involved in intrigue across time and space as she tries to find her inventor-turned-teacher Ms. Trombone. She time travels with one of Ms. Trombone's inventions, the Intellicat. Includes a guide for teachers and parents with lesson plans. For girls 9-11 years of age. We want to give real girls good content and provide real historical rol

This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers the origin of basaltic magmas. Two types of basalt in ocean basins are compared (tholeiitic and alkaline). Composition of mantle-derived magmas and sources of mantle material are listed. Discussion of how the mantle melts, touching on the contribution of volatiles, pressure and composition, is included. The slide show includes figures comparing enriched vs. depleted mantle. This resource is part
Geometry Formulas and Facts
This excerpt from the CRC Standard Mathematical Tables and Formulas covers geometry, excluding differential geometry. It is a reference for advanced students, and covers the material in quick, condensed sections of notes. Notes and diagrams are organized into sections and subsections, starting with coordinate systems, plane transformations, lines, and polygons in two-dimensional geometry. The section on three-dimensional geometry covers coordinate systems in space, space symmetries, directions,
This tutorial on crystallography is broken down into equipment set-up, x-ray diffraction basics, symmetry and space groups, structure factors and phase problems, phasing techniques, model building, and real space correlation plots. Diagrams and interactive topics accompany the text, along with an interactive applet on Bragg's Law.
Baseball Cards, 1887-1914
