Three children collect parsnip seeds from a plant grown last year on their allotment. They prepare the soil, plant and water them, explaining why this is important. They dig up a parsnip and prepare it for eating. Then they visit an enormous farm in Norfolk where they see radishes grown, harvested and prepared while the farmer explains the processes involved.
Pupils can be given, or make, a comic book style strip of frames in which they will draw each step the children took when trying to grow the seeds or the radishes. They can then be asked to explain their picture to the class. This is also an opportunity for paired or grouped activity.
