What is a Compass

There are rocks on earth that are magnetic called magnetite, which actually means magnet mineral. Ancient scientists found that they could use magnetite to help them make a compass.

A compass is really just a magnet that always points to the North Pole of the Earth. It is useful for navigation, whether you are walking in the wilderness or sailing a ship. A compass, along with a map, can show where you are and what direction you need to go in.

How to Make a Compass

This homemade compass is a fun and easy STEM activity for kids of all ages!

SUPPLIES:

  • Magnet
  • Needle
  • Plastic bottle cap
  • Bowl of water

INSTRUCTIONS:

STEP 1: Turn the needle into a magnet by rubbing it along the surface of the magnet about 60 times.

Be sure to rub the needle in the same direction every time. Pretty soon, the needle will become magnetic, too!

STEP 2: Lay the needle on the rim of a plastic bottle cap.

STEP 3: Carefully float the bottle cap in a bowl of water so that it is free to move around.

The needle will slowly turn the bottle cap around until it points to the North Pole!

Please note: if it does not work, rub the needle with the magnet again.

How Does a Compass Work

The Earth is a giant magnet with its own unique magnetic field. The magnetized needle is attracted to it and points to the “magnetic north pole” of the Earth’s giant magnet.

The compass you will make below works just like the compass on a ship or in a car. These compasses also use a magnet held by something that allows the needle to float very evenly. Often it will be a liquid that does not freeze like oil.

What is STEM?

So you might ask, what does STEM stand for? STEM is science, technology, engineering, and math. The most important thing you can take away from this is that STEM is for everyone!
