You probably know that you can use iron filings to reveal the magnetic field produced by a strong magnet. If you sandwich the iron filings between pieces of waxed paper, you can make a permanent record of your magnetic experiments (Gardner, 2004, 66). Cover the wax paper sandwich with a layer of brown paper (from a roll, or cut open a paper shopping bag), and then (with an adult's help) use a hot, dry iron to seal the waxed paper together. You will have to experiment a little with your iron…

How can you make a train without wheels? By using magnets! In this project you will build a magnetic levitation ("maglev" for short) train that floats above a magnetic track. How much weight can you add to the train before it sinks down and touches the track?

If you like playing electric guitar, this could be a cool project for you. Have you ever wondered how an electric guitar works? In this project you'll wind one or more of your own electric guitar pickups and test them out in an inexpensive electric guitar. How will the sound change with the number of turns you use in the coil? Or with the strength of the magnets you use?

How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a short piece of DNA, called a primer, that will stick to the larger piece of DNA you want to copy, called a template. In this science project, you will test how the number of matches and mismatches in a primer will affect its ability to stick, or anneal, to the DNA template during PCR.

Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try!

The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity.
You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity.

You've seen that a magnet's attractive force can cause a small object (like a paper clip) to "jump" to the magnet. So a magnetic field can act through the air, but what about other materials? Here's an experiment you can do to find out. You'll need a strong bar magnet, a stack of books, a paper clip, some thread and tape. Place the bar magnet underneath the top book in your stack, so that it sticks out. Tie a piece of thread (as long as the stack of books is high) to a paper clip. You…

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased.

Can you build a working speaker out of paper? How does a speaker's ability to play low or high-pitched notes depend on its size? Explore the science of sound in this project as you build and test your own speakers in order to answer these questions!

Does your home have any pet doors or gates for dogs, cats, or other animals? Some automatic pet doors can be set up to allow only certain animals through. These doors can help you control which pets are able to go outside alone or which ones have access to specific food, litter boxes, or toys. But why buy such a door when you can make one? In this project you will build your own automatic pet door that works with a magnetic collar tag. Exactly how you use it is up to you!
