How does compass find North?
There is liquid metal spinning inside the earth, which creates a magnetic field. The compass lines up to the magnetic field and it will point in the north direction.
How can you make a compass?
In our class we did an experiment of making our own compass, we need water, a needle, plastic bow, paper and a magnet. We rub the magnet on the needle for 5 minutes, and we pour the water in the plastic small bowl. After 5 minutes we get a small piece of paper and put the needle on top of it and we have to put it in the water, and try not to sink it or else it will fail.
