The cardinal directions
Standing in a field or on a hill, we see a line where land and sky seem to meet. This is the horizon. We can never reach it: as we approach, it moves away. The world has four main directions: north, south, east, west. The Sun rises in the east and sets in the west. If you face north, south is behind you, east on your right and west on your left. A compass needle always points north because it is magnetic.
Experiment “Make my own compass”: with an adult, stroke a sewing needle 30 times in one direction with a magnet. Push it through a small piece of cork or foam and float it in a bowl of water. The needle slowly turns and lines up north–south. Compare with a real compass. Safety: only an adult handles the needle; keep magnets away from phones and bank cards.
