National Water Week will be celebrated next week. We are encouraged to ‘protect, conserve and get involved’ in appreciating our water supply. The poster competition is an annual event for Australian schools.

A rainbow is an arc of spectral colors, usually identified as red, orange, yellow, green, blue, indigo, and violet, that appears in the sky opposite the sun as a result of the refractive dispersion of sunlight in drops of rain or mist.
Refraction of Light happens when light travels from one transparent medium to another and changes speed.
This causes the light to bend. Look at a pencil in a glass of water.
