This is Crayons' current science project, from the "Changes" unit in Herb Strongin's book Science on a Shoestring.
Requirements: plastic shoebox, paper towels, masking tape or painter's tape, birdseed containing several different kinds of seeds, water, patience.
Method: Sort out the birdseed so that you have about ten seeds each of as many different kinds as you can find in the package. (We used sunflower seeds, milo, and millet, and added popcorn as a fourth type.) Line the plastic container with dampened paper towels, and divide it into sections with tape. Arrange the seeds in rows in each section. Put the lid on, dampening the paper towels again if and when needed. (According to the book, some mould is to be expected.)
