Demonstrating how the angle of the sun's rays changes from day to day at the same hour

Cut a 1-cm round hole in a piece of paper or cardboard. Place this in a south window of your classroom where the sun's rays will shine by the hole and strike a piece of white paper on the floor, the table or window sill. Draw the outline of the spot where the beam of light strikes the paper. Write the date and hour inside the outline. Repeat this on succeeding days at exactly the similar hour
