Human eye does not see very well in the dark. This is a simple and fun experiment involving night vision for kids.
What You Need:
Get five pieces of paper in different colours and a pencil. Go to a room and dim the lights until you can scarcely see. Wait for about 10 minutes, and then guess the colour of each piece of paper and write the name of the colours on them. Turn on the lights and see if your answers are correct. You will see that you made many mistakes.
As you know, you cannot see when it’s completely dark, but you can see a bit in dim light. When the light is dim, the receptors in your eyes called rods help you see. However, the rods do not provide any information about colour. It’s the receptors called cones that distinguish between different colours, but cones don’t work well in dim light. As a result, you did not see colours well in dim light, and made mistakes in guessing the colours.
