Key Concepts
Rainbow: A rainbow is a large, curved band of colours that appears in the sky after it rains when the sun shines. It has seven colours.
Colours of the rainbow: The seven colours in order are: Violet, Indigo, Blue, Green, Yellow, Orange, Red. An easy way to remember them is the name VIBGYOR (V-I-B-G-Y-O-R).
Describing what we see: We can describe the rainbow by its colour, shape, and when it appears. A rainbow is curved (like a big arch or a half-circle).
After the rain: A rainbow appears when rain has just stopped and the sun comes out. Tiny drops of water in the air break sunlight into seven colours.
