Fieldwork lesson: Secrets from the ditch
Working in the ditch with scoop nets, aquarium trays and search cards guarantees an active and educational lesson. Together with an educator from the Helderse Vallei, pupils discover which animals live in the ditch and what they need to survive here. How clean or dirty the water is plays an important role in this. You can even make a statement about the quality of the water by the presence of some animals.
