Fieldwork lesson: Secrets from the ditch
Working with scoop nets, aquarium tanks, and identification charts at the ditch guarantees an active and educational lesson. Together with an educational staff member from Helderse Vallei, students discover which animals live in the ditch and what they need to survive there. How clean or dirty the water is plays an important role in this. You can even make a statement about the water quality based on the presence of certain animals.
