Pbs Teachers: Scientific American: 21st Century Medicine: Image Guided Surgery
Investigate the science and medical diagnostic uses of magnetic resonance imaging (MRI) technology. Perform experiments to observe how magnetic properties can be induced, and measure the force of temporary magnets.
American Geosciences Institute
American Geosciences Institute: Earth Science Week: Mineral Identification
At this site you can identify minerals by observing and testing the physical properties of each mineral. A mineral worksheet and mineral background sheet are included in this site.

The Nobel Prize: Otto Stern Biographical
This is a brief biography on the life and scientific work of Otto Stern, a physicist honored with the Nobel Prize in physics for his "development of the molecular ray method and his discovery of the magnetic moment of the proton."
Discovery Education
Discovery Education: The Em Spectrum: Waves of Energy
Students are introduced to the electromagnetic spectrum through this group research activity. Each group investigates a different wavelength range within the em spectrum and reports back to class. Discussion ideas also included.

Teach Engineering: Clean Up This Mess
Students are challenged to design a method for separating steel from aluminum based on magnetic properties as is frequently done in recycling operations. To complicate the challenge, the magnet used to separate the steel must be able to...

Teach Engineering: Building an Electromagnet
Students design and construct an electromagnet that must pick up 10 staples. They begin with only minimal guidance, and after the basic concept is understood, are informed of the properties that affect the strength of that magnet. They...
Florida State University
Florida State University: Molecular Expressions: Electromagnetic Radiation
This Florida State University page introduces light as an electromagnetic wave and discusses the frequency and wavelength range of the various regions of the electromagnetic spectrum. Includes links to some interactive Java applets.
Georgia State University
Georgia State University: Hyper Physics: The Meissner Effect
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.
Exploratorium
Exploratorium: Science Snacks: Curie Point
Did you know that a piece of iron can lose its magnetism if heated too high? There is a point called the Curie point when iron is heated to a high enough temperature that its iron atoms are scrambled and can't line up to form a magnetic...
Curated OER
Exploratorium: Diamagnetism Push Me a Grape
An online activity which illustrates the magnetic property of diamagnetism associated with water. Contains a simple procedure and then a good explanation of the magnetic interactions that were displayed by the grapes.
Florida State University
Florida State University: Molecular Expressions: The Buckyball Collection
General information of buckyballs and a description of buckyballs containing ions, called dopeyballs, which have superconducting properties. Colorful photomicrographs of fullerenes on thin films.

Teach Engineering: Eat Iron?!!
To gain an understanding of mixtures and the concept of separation of mixtures, students use strong magnets to find the element of iron in iron-fortified breakfast cereal flakes. Through this activity, they see how the iron component of...
