Division 7 has been exploring the properties of light.  One of its properties is colour.  We learned that although sunlight looks white, it is really a mixture of many different colours.  These colours can be seen when a rainbow forms.  Rainbows happen after rain, when the air is full of tiny water drops.  As sunlight passes through the droplets, the different colours are separated so that you can see them. Have you ever seen anything else that can make a rainbow?  

Here we are using soap bubbles to find the colours in light.[metaslider id=3120]
