Creating a Cloud Notebook And Growing Birds' Nests

I found a couple of neat ideas in a library book I was reading today and thought I would "file" them here, so I don't forget about them. 

The first idea was to create a cloud diary using cotton balls stretched out to show how the clouds look each day. I thought this would be a great idea to use in a notebook or lapbook on weather to show the different types of clouds.

The second idea was to place an abandoned bird's nest in a shallow pan with 1/4 inch of water. After a few days, any seeds that were left in the nest will grow, and you will be able to see what the mother bird fed to her babies. I'm guessing this would only work with certain types of birds' nests, but it sounds fun anyway.
