As part of the whole school Science Fortnight, we began the first week with a whole school assembly led by 'Mad Science' scientists. There were pops, bangs, wows and bubbles overflowing from conical flasks. There was some audience participations to create the 7 colours of the rainbow. 

Later, each class had a workshop called 'Lights, colour, action.' The children were shown some different light sources and were given a special pair of glasses to look at the lights. They went outside as it was sunny and realised that the glasses made them see rainbows. Once back inside, the children were shown how to use coffee filter paper to show how different colours are made up.  Each child got to draw on filter paper before using pipettes to wet their paper, making the colours separate.  Some children got to watch how skittles placed in water also draw out the colours. Look for more ideas about this on Youtube. Finally, the children watched as different chemicals reacted when put over a flame producing different colours. It was like watching silent fireworks especially when a mix of chemicals were used as it meant different colours could be seen.

Back in the class the children explored and experimented with ice, linked nicely to our core story, Lost and found, where the penguin lives in the South Pole.
