Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.
Could be used as an introduction to plants and reproduction. Pupils could write a non-fiction report on plant reproduction or the process of pollination. A webcam could be set up to record bees and insects in a garden area of the school to monitor pollination in the children's own environment. Pupils could create a series of cards depicting pollination, which their partner then has to sequence.
