Maria wants to know if birds prefer one color of feeder to another. She makes three feeders out of 2-liter bottles and paints one red, one blue, and one green. She fills each of the feeders with the same amount of mixed birdseed, and plans to keep the feeders out for 10 days before measuring how much seed is eaten from each feeder. She puts each of the feeders in the school courtyard in a small tree, hanging each at the same height. How is this experiment fair/or unfair and why?
