In Reception this week we have been investigating the question 'Do ducks get wet?'. We investigated what we mean by waterproof and tested some materials to find out if they are waterproof. We learnt about ducks preening and using preening oil to keep their feathers waterproof. We designed coats and umbrellas out of waterproof material for ducklings and even ventured outside into the rain to see if our own coats were waterproof or water resistant.
