We have been learning about the adaptations of birds that live in or around water. We learnt that ducks have a special oil that they spread over their feathers to keep them warm, dry and floating. We tested this out using a cotton ball as the duck and oil.
When we didn't put any oil on the duck it sank!
When we only coated the bottom of the duck (the part that the water touches when it swims) it turned over so the oil side was up and floated upside down! This was not ideal and the duck wouldn't be able to breathe or survive!
Lastly we coated the whole duck with oil and it floated on the top of the pond! Yay!
This is because oil floats on top of water!

What an interesting experiment Room 3. I wonder if other birds have oil on their feathers? Keep up the awesome learning!
