Investigating colours and light
one 10cm circle of card each, string or a cocktail stick, colouring pens, pencil
Print out coloured segment cards and, if running activity alongside other experiments, cut them out prior to meeting to save time. Beavers then use a pencil/pen to make the hole in the centre. Slip the spinner onto a length of string or wool. Ask the Beavers to predict what will happen before they start spinning.
