There are so many authentic projects that can be inspired by bird feeders. Do different kinds of birds need different kinds of feeders? Do different kinds of birds eat different kinds of bird food? Once you start feeding birds it is important to not stop. Why? How about designing and building a bird feeder? (Research/reading, writing, math, science…)
In my neighborhood we have a huge problem with bears feeding from the bird feeders. To the point that we have been asked to not put out bird feeders.
So maybe a great authentic project would be to design a bear-proof bird feeder. Let me know what you come up with – I would love to be able to put up a bird feeder in my backyard!
