PBL activity -- Checking and Action (Woodlands Primary School)

We did some changes in our planning, we plucked out the leaves and made sure that the stem was of the same height. After the experiment, we got a blue and a little green colour in the rose. but the carnation only had blue coloured petals. The outcome of our prediction was wrong because it was suppose to be really half blue and half green, yet it is more blue than green (Rose). The carnation was only blue colour. To improve the experiment we must have petals of the same size, we should also have the same shade of dye.
