Links

Select the link "Magnetism: A Magnetic Attraction" in the Science section of the site to watch an animated movie and learn about magnetism, an iron ore magnetite and its magnetic field. Click on the "Ex-Lab Rat Bob" icon for a fun experiment with magnets, select "The Activity" icon for a crossword, and visit the "Timeline" to find out when magnets were first mentioned. NOTE: The web site is available by subscription only.
Here is fun craft for younger kids. Create different animals using bendable magnets and colored pipe cleaner. NOTE: The site includes ads.
Here is a worksheet for third and fourth graders. Read about magnetic fields and poles than answer questions.
Explore links on this page and find answers on many questions about magnets such as what are permanent and temporary magnets, who discovered magnets, how compass work, and many more.
Did you know that the Earth is a giant magnet? Read about it here.
Find out why compass is always points to North and how Earth acts as a large magnet.
Learn more about the Earth's magnetic field, its origins, and what its role of protecting life on the planet.
Read about a new class of neutron star, Magnetar. These stars create incredibly strong magnetic field.
Read facts about magnetism. NOTE: The site includes pop-up and banner ads.
Here are several magnet experiments you can try. Many require electricity and certain types of magnets so you should ask an adult for help in setting them up.
This interactive module gives simple explanations of how electricity, charges, circuits, and magnets work. It begins with a thorough look at electricity, and then at the relationship between electricity and magnetism.
Read about magnetism then answer questions using this worksheet.
This worksheet is designed for fifth and seventh graders. Learn about magnetic attraction then use this worksheet to answer questions.
Choose among several experiments and learn how to build a magnetic heat engine, suspend a magnet in the air, and more.
This site from Maryland's transportation department explains how a magnetic levitation train works and includes a short Quicktime video of Germany's test train.
This is a brief explanation on electromagnetism. NOTE: The site includes pop-up and banner ads.
Find out how relations between magnets and electricity were discovered and explained by the Electromagnetic Theory. Learn about a motor, a device that has ability to convert electrical energy into mechanical energy. Also learn about another device - generator that is used when mechanical energy is transferred into electrical energy. Discover what electromagnets are and how they work. Includes photographs, animations, and experiments.
These sites cover the basic concepts of physics. Learn about force, motion, and friction using interactive simulations where you can manipulate the variables. Includes a link to an eThemes on Simple Machines and one on Magnets.
These sites explain how the earth's gravity works. Includes photos, simulations, videos, hands-on activities, and online quizzes.
