(Photograph) - Ask your class to look at this picture of a rainbow. How many colours can they see in it? Can they name each colour?
Have they ever seen a real rainbow? The best time to see one is when there are rainshowers and sunshine together. In our picture the artist has made the seven colours separate and easy to see. A real rainbow changes colour gradually from side to side.
Can they see the reflection of the rainbow in the water? Do the colours look just the same? Can they say what is different about them?
Can they name the colours in the word "rainbow" under the picture?
Is the grass all the same green? Can they describe the differences between the shades of green?
