"Just the Maths"
Developed by a retired mathematics professor from Coventry University, this website "is a collection of separate units, in chronological topic-order, intended to service foundation level and first year degree level courses in higher education, especially those delivered in a modular style." Although there are separate sections for students and teachers, both contain essentially the same information except for the format of the material -- printable pages with slightly more detailed explanations
Using Geographic Information Systems to Map Crime Victim Services
The US Department of Justice released this document in February 2003 about the use of geographic information systems (GIS) in law enforcement. "GIS is an application that links database software to graphics software to create visual images of various types of data in map format." The report outlines the applications of such systems in police cars and at victim assistance facilities, providing examples of situations where it has been used successfully and cases that could have benefited from GIS.
Glossary of Energy Terms
The California Energy Commission's Web site contains a great resource entitled the Glossary of Energy Terms. If you're interested in energy topics or happen to come across an unfamiliar term, this tool will be of great use. Simply choose the letter of the term and hope that it's included -- for example, DAYLIGHTING, which is defined as "The use of sunlight to supplement or replace electric lighting." If you quickly get through the hundreds of terms within the dictionary, the main page offers a l
National Speleological Society (NSS)
At this website, the National Speleological Society (NSS) promotes its goals "to study, explore, and conserve cave and karst resources; protect access to caves; encourage responsible management of caves and their unique environments; and promote responsible caving." Individuals can view amazing images of the twelve preserves managed by NSS. Students and educators can investigate links offering virtual tours of caves, cave exploration safety, and materials about the geologic characteristics of ca
University of Illinois at Urbana-Champaign: Computational Astrophysics: Digital Demo Room
This University of Illinois at Urbana-Champaign website features four computer simulations to increase the understanding of astrophysics: Disk Galaxy Dynamics, One Dimensional Hydrodynamics, Stellar Structure and Evolution, and Two Dimensional Hydrodynamics. Each simulation offers beginner, intermediate, and advanced modes. At the Stellar Structure and Evolution Simulator link, individuals can find a tutorial describing the basic physics concepts related to the topic along with the interactive m
Ultrascale Simulation for Science
When Japan's Earth Simulator supercomputer eclipsed its US counterparts in terms of speed and processing power, America was faced with a challenge to regain its dominance of supercomputing capability. The Ultrascale Web site studies this challenge, and the implications it has on the nation's scientific objectives. Several short documents about the importance of and applications for ultrascale simulation are given on this page. Generally between one and two pages, the papers are mostly from the U
The Ciliate Resource Archive
The Ciliate Resource Archive is a web site featuring a wealth of information on ciliates for educators, students and the general public. The site includes a glossary of terms, a list of valid type species and classification information. The site would be helpful for students researching ciliates or instructors developing related coursework.
Design Packing to Safely Mail Raw Spaghetti
Students will use their creative skills to determine a way to mail raw spaghetti. The students will need to choose a way to safely package their raw spaghetti using only the materials provided. To test the packing designs, the spaghetti will be mailed through the postal system and evaluated after delivery.
Reading comprehension: What works?
Teach reading comprehension in the elementary grades with flexible strategies that connect reading to the real world, promote independence, and keep students engaged.
The manufacture of products requires massive amounts of energy. This informational piece, part of a series about the future of energy, introduces students to the energy needs of the manufacturing community. Students explore three ways that manufacturing uses energy and the importance of fossil fuels to the manufacturing sector. A replacement for fossil fuels is suggested. An article on manufacturing soft drink cans is accessible from a sidebar. A link to a PBS NewsHour article on communities tha
Groups of students make a polymer out of household items. They then experiment with the polymer to determine its various properties.
Manufacturing Technologies: Making a Picture Frame
The basic processes involved in manufacturing systems are demonstrated while students produce their own picture frames. They learn about cutting, shaping, assembly, joining and finishing, as well as attention to quality, safety and production quantity.
Make Your Own Recycled Paper
Students will learn about how paper is made. Working together, students will make their own paper. This activity introduces students to recycling; what it is, its importance, and how it affects their lives.
Journey to the Afterlife
In groups of four, have students design an Egyptian funerary barge to transport the mummy through the underworld to the afterlife. The design of the boat is extremely critical in order for the mummy to have a chance to reach and enter the afterlife. In planning the design of the boats, students should be aware of the perils of the underworld. The student will be given the materials and tools the ancient Egyptians had at their disposal in constructing the boats. Once the students have determined

He is senior member of the Federal Reserve System's Federal Open Market Committee, the key body with authority over national monetary policy in the United States.
Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of various environments and the engineering design process to design and create their own model biodome ecosystems - exploring energy and nutrient flows, basic needs of plants and animals, and decomposers. Students learn about food chains and food webs. They are introduc
The Fundamental Building Blocks of Matter
This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Students think about how atoms and molecules can influence new technologies developed by engineers.
Amusement Park Ride: Ups and Downs in Design
Students design, build and test model roller coasters using foam tubing. The design process integrates energy concepts as they test and evaluate designs that address the task as an engineer would. The goal is for students to understand the basics of engineering design associated with kinetic and potential energy to build an optimal roller coaster. The marble starts with potential energy that is converted to kinetic energy as it moves along the track. The diameter of the loops that the marble tra
