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.
Mission to Mars
This educational module is designed to teach students about models and data collection and analysis using a Mars Mission as an example. The activities in this module require students to gather observations and data and use this to generate a model that illustrates a real object, in this case, the surface topography of a landing site on Mars. This module allows for students to have increasingly sophisticated experiences with this concept as well as an opportunity to utilize science process skills
Civil engineers design and construct structures such as buildings, dams, and bridges. We can explore the field of engineering by making a bridge using spaghetti. This bridge is then tested based on the weight it can carry without breaking.

Visitors can be guided through the site tour, browse, or search for specific topics. The site is interesting and informative.
Biology is the science of life, the branch of the natural sciences that studies living organisms.
Demonstrations and Animations for Teaching Astronomy
This website is intended for teachers to use these animations in class to illustrate important astronomy concepts like: lunar phases, Keplers Laws, retrograde motion, the Doppler Effect, spectral lines, Kirchoffs Laws, and the seasons.
Sketches of the history of Electromagnetics
This website outlines the history of light, electricity, magnetism and electromagnetic theory, placed in a linked timeline order with corresponding biographical sketches. It includes events from antiquity to 1933.
Superbug Survival is Basic
This on-line news article investigates the question: Can microbial life thrive in the caustic conditions common to floor strippers and baking soda? It reports samples near a landfill in south Chicago that reveal alkaline solutions are basic to certain bacterial superbugs. The article explores the habitat, genetic analysis, and close relatives of these microbial wonders while also conveying that much more research is needed in the area. Useful links are located at the end of the article.
Methods and Strategies : Using Models Effectively
Models are crucial to science teaching and learning, yet they can create unforeseen and overlooked challenges for students and teachers. This article guides students through age-appropriate, critical analyses of instructional models.
Fascinating pickle facts
Each of this feature's nine paragraphs describes a fact about food produced through fermentation around the globe. The facts present a mix of history and science. For example, one paragraph explains how pickles were instrumental in Spain's discovery of America, while another reveals why modern-day outdoor fermentation vats are intentionally left uncovered. Another paragraph summarizes how osmosis and the bacteria involved in pickling can make vegetables more vitamin-rich. In addition, historical
What's a quick way to unroll a roll of toilet paper? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use Bernoulli's principle and an electric leaf blower to force air over the top of the toilet paper to quickly unroll it. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provided are c
Developing Alternative Assessments using the Benchmarks
Written from the perspective of a classroom teacher, this article describes a process for developing alternative assessments, provides examples of alternative assessment tasks and student responses, amd illustrates the use of scoring rubrics. The examples use the AAAS Benchmarks for Science Literacy and the National Science Education Standards to identify learning goals. This resource is intended for use in the classroom by K-12 teachers.
PBS provides students in grades 4-7 with oodles of science fair ideas and a science fair tip sheet in this section of the DragonflyTV web site. Overviews of investigations from the television show are offered to help students hone in on an interesting topic and create their own science fair project. Each overview relays a question that a child asked on television, the main steps in his or her experiment, and the results. The overviews also include ideas for further investigations that build on t
This is a simple activity to visualize a communication system. In order to do this the students encode, decode, transmit, receive and store messages. They will use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve information as and when it is required.
Science News For Kids
This resource is meant to enhance the usefulness of Science News in the middle-school classroom and offer recreational reading and activities for students interested in science. It is comprised of six zones: a weekly brainteaser for those who enjoy solving and inventing puzzles, entertaining science-fiction composition exercises for those interested in writing, and weekly science fair profiles and tips. The GameZone contains a small selection of logic and memory games, implemented as Java applet
