Join the STEAM Powered Family newsletter to get regular updates and access to free resources. The compass, historically one of the most important aids to navigation, helped to drive the great sea voyages of Europe’s Age of Discovery. What happens if you spin the compass? Use a Magnet to Magnetize the Needle. Put some water in a container. Watch as the circle begins to spin around until the needle is pointing in the direction of north, just like a compass. A compass needle can be made from any piece of metal that can be magnetized. WHAT YOU NEED: A bowl of water, cork, sewing needle and a compass. Pretty cool, eh? We use the bowl of water because Earth’s magnetic field is relatively weak. Navigation Set out your bowl and fill it with a few inches of water. It was completely fascinating. In this science activity you'll get to make your own magnetic compass. As you may have gathered, this is important. Option 1: While most of us probably aren’t going to have a magnet with us while out in the field, if you did for some reason have one ,you use it to make your compass. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. Scissors. If you run into trouble try using a stronger magnet or rubbing the magnet more times on the needle. But for most good quality magnets 50 should be about right. The needles are sharp. This in turn led to a lifelong fascination with invisible forces. In this activity we explore how magnetic forces control the movement of the needle by learning how to make a compass out of household items. I had researched the making of a permanent magnet and thought the process was definitely do-able, but found out that with such a small piece of metal it's actually very difficult. You will need a small cup of water, a leaf, a metal striker such as a file or pocket knife, and a paper clip. We love learning about how these brilliant minds lived. This idea originally came from Quirky Momma , but I didn’t have a cork…so I improvised (and use Steve Spangler Science for a little help as well). The body was simple enough to make, but now I'm stuck on the needle. This is a great science experiment to perform with the kids. Straighten the paper clip so it as straight as you can get it. What happens? It is a wonderful way to inspire kids and teach them the value of perseverance, imagination and about how great discoveries have happened in history.

Ensure you have appropriate adult supervision and children are old enough to behave safely. Always rub in the same direction. Specifically, once it stopped moving, the needle should have aligned itself along Earth's magnetic field, lining up along the north/south axis. A stronger magnet will work best. Have an adult help or perform this step. Create a second compass and add it to the same bowl of water. Now cut off about one quarter inch of the cork from one of the ends, making a small cork disk that is about one-quarter-inch tall. It is incredibly easy to do and the kids were fascinated by the movement of that needle! If you are using a weaker magnet you may need to do this more than 50 times.

Although the phenomenon of magnetism has been known of for a couple thousand years, the first magnetic compasses used for navigation were not invented until relatively recently, approximately 1,000 years ago (sometime between A.D. 1000 and 1100). Because magnets interact with one another, either attracting or repelling, the magnetized needle can interact with the Earth’s magnetic field. They’re known for high quality products made in Finland and reliable navigation equipment from digital wrist computers to highly accurate orienteering compasses.
