Here's a project for studying compression waves in different soil types. It uses a homemade wave tank for solids, with a frequency generator, amplifier, and loudspeaker as the vibration source. There are lots of interesting possibilities...

Use the left navigation to access a solid history of opera as developed in various countries. You can also find synopses of opera stories, full opera libretti, and an index of opera composer's works.

A discovery by Hans Christian Orsted forever changed the way scientists think about electricity and magnetism. While preparing to perform an experiment during a lecture at the University of Copenhagen, he found that the magnetized needle...

The circle is one of four different shapes which can be created using "slices" through a cone, a 3-dimensional solid that has a circular base joined to a single point (called the vertex) by a curved side. If you tilt a cone, you get an...

Instructions on how to carve a small sculpture using plaster of Paris, a table knife and spoon. Also included is background information on the emergence of modern sculpture.

Educational resource invites users to understand the properties of water by first examining what water is and how we use it and then leads users to further information on the three states that water can exist.

This website, from the University of Edinburgh, provides a lengthy glossary of computer graphics terms written by Olin Lathrop, author of "The Way Computer Graphics Work". This site provides simple definitions of basic terms; no graphics...

Practice matching 2D nets to the 3D shapes the fold up into. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice using the net of a 3D figure to find surface area. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice finding the surface area of 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This informative and interactive site examines how we can get power from garbage. Topics include: waste to energy plants, only ash remains, a bright idea, and more.

Presents a general overview of fuel cells including what is a fuel cell, how do they work, and the different types.

This activity allows the user to find the volume and surface area of various functions as they are rotated around axes. This applet can be used to practice finding integrals using the disk and washer methods of calculating volume.

[Free Registration/Login Required] The ways in which nouns and adjectives e.g. fix, simple, solid, drama, can be made into verbs by use of the suffixes -ate and -en. Investigate spelling patterns and generate rules to govern the patterns.

Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means. Students will participate in hands-on activities to prove that matter is made up of...

Find a quick, concise explanation of what a polyhedra is. Examples are given and clearly explained.

This question and answer site from The Math Forum with Dr. Math discusses the angle between two adjacent faces of an octahedron. Links are also provided for additional information on related subjects.

This site from the Georgia State University provides a good overview of ferromagnetic materials, introducing concepts such as magnetic domains, hysteresis, the curie temperature, and magnetostriction.

A great introduction to magnetic domains, including pictures which illustrate the effect on domains caused by external applied magnetic fields.

This site from the Georgia State University provides a good introduction to and illustration of the Meissner Effect, the property of a superconducting material whereby it actively excludes a magnetic field from within its interior.

A brief definition of the Curie temperature for ferromagnetic materials.

This site from the Georgia State University provides a brief introduction to diamagnetism, explaining how Lenz's law accounts for diamagnetic behavior in all materials.

This site from the Georgia State University provides a brief introduction to paramagnetism, explaining how paramagnetic materials exhibit magnetization proportional to an applied magnetic field according to Curie's law.
