We have an easy way for kids to make a compass on their own.
This simple magnetic compass needs only a few basic household supplies (we thought you’d like that!). Kids Activities Blog loves helping kids learn about the world around them with simple hands-on projects like this.

Make a Compass
It’s easier than you might think to make a compass. All you need are a few simple household items and you can put together a compass that shows due North with surprising accuracy.
To make a compass, all you need are four simple items:
Cut a small circle from a material that will float in water. We used some craft foam but cork or even a piece of paper will work.
The next step is to turn the sewing needle into a magnet. To do this, stroke the needle across the magnet about thirty to forty times.
Be sure to stroke in one direction only, not back and forth. Now the needle will be magnetized!
Next, place the needle on the circle of craft foam or cork and place it on top of the water.
Try to place it in the center of the bowl, keeping it away from the edges. The needle will begin to slowly turn around and eventually the needle will point North and South.
We were so amazed to watch the needle finding North and we checked the accuracy of our DIY compass with a compass app (we used Compass from Tim O’s Studios. It was free to download and very simple to use).
How it works
Every magnet has a north and south pole. A compass is small magnet that aligns itself with the north and south poles of the Earth’s magnetic field. As the needle is stroked across the magnet, it becomes magnetized because the electrons within the needle straighten up and align themselves with the magnet.
Then the magnetized needle aligns itself with the Earth’s magnetic field, when it is placed on top of the water.
