a DIY compass can be a fun and educational activity for kids. Here’s a simple way to make a homemade compass using common materials:

Materials Needed:

  1. A small bowl of water
  2. A small bar magnet or a strong refrigerator magnet
  3. A small piece of cork or a small, light object that can float
  4. A pin or needle
  5. A piece of paper
  6. A marker or pen


Step 1: Magnetize the Needle

  1. Rub one end of the needle against the magnet. Do this several times in the same direction. This process magnetizes the needle.

Step 2: Float the Needle

  1. Place the piece of cork or the small floating object in the bowl of water.
  2. Gently place the magnetized needle on top of the floating object.

Step 3: Mark the Directions

  1. Once the needle settles and aligns with the Earth’s magnetic field, mark one end of the needle as the north (N) pole and the other end as the south (S) pole.
  2. Use the marker or pen to mark the directions on the edge of the bowl. You can label them as North, South, East, and West.

Step 4: Observe and Experiment

  1. Watch as the needle aligns itself with the Earth’s magnetic field, pointing in the north-south direction.
  2. Rotate the bowl gently and observe how the needle follows the magnetic field.


The Earth has a magnetic field, and a compass works by aligning itself with this magnetic field. The magnetized needle becomes a tiny magnet and aligns itself with the Earth’s magnetic poles. The marked end of the needle points towards the Earth’s magnetic north pole, making it a simple and effective compass.

This DIY compass project not only introduces kids to basic concepts of magnetism and Earth’s magnetic field but also provides a hands-on experience in creating a functional compass. It’s a great way to spark curiosity about science and navigation.
