This project involves making a simple DIY compass to understand how magnetism works and how it relates to the Earth's magnetic field. It's an exciting way to explore physics!
If I create a compass using a magnetized needle, then it will align itself with the Earth's magnetic field and point north.

Magnetize the needle by rubbing it with a magnet in one direction.
Insert the needle through a piece of cork, making sure it's balanced.
Fill a bowl with water and place the cork with the needle on the surface.
Observe the needle as it aligns itself north-south.
Mark the directions on a piece of paper using a compass rose template.
Perform tests by rotating the compass in different locations.
Discuss the significance of Earth's magnetic field.
Present your findings at the science fair.
You should see that the needle aligns itself with the Earth's magnetic field, providing a clear demonstration of how compasses work.
