Less than 10% of plastic trash is recycled -- compared to almost 90% of metals -- because of the massively complicated problem of finding and sorting the different kinds. Frustrated by this waste, Mike Biddle has developed a cheap and...

In this video Paul Andersen explains how all material has magnetic properties. Ferromagnetic material can be permanently magnetized, paramagnetic material will align with magnetic fields, and diamagnetic material will align weakly with...

2 minute video demonstrating magnetism and magnetic properties for middle school science

Howcast - Initial searches for oil on land usually require the skills of geologists and geophysicists. These searches are often conducted by small exploration companies called wildcats.

Materials can be classified based on their response to external magnetic fields. Diamagnetic materials are weakly repelled by external magnetic fields, while paramagnetic materials are attracted but lose their magnetism in the absence...

Explore the role of magnets in our daily lives, from the fridge magnets holding up photos to the science behind compasses. This easy-to-understand guide covers the basics of how magnets work, including their attraction and repulsion...

Materials engineering (or materials science and engineering) is about the design, testing, processing, and discovery of new materials. Materials engineers will cover the 4 main classes of materials...
