One of the tools I use for teaching light source is a cardboard box. I cut a flap in the middle of the top and the sides. One end of the box is open and when set down on a table with the opening facing the viewer it is now a stage. Sit objects inside it. I use teddy bears. Use a torch and open the top flap. Shine the torch on top of the teddies through the flap. The light source is coming from the top. Discuss where the light is hiiting the top and creating shadows where it canīt strike at a surface. Discuss the colours we see in this. Now shift the torch to the left and right flaps doing the same thing. Just walking through this process with your students will help them to visualise the light source.
