My colleagues of are no help (or don't seem to want to help) me substitute for this lesson plan. On Thursday, we have plans to make a bird feeder out of a pine-cone, peanut butter, and bird seed so we can hang them on our "class tree". I have a kid that has a nut allergy, to all kinds of nuts. Now yes he can be around it but I'd rather not risk him accidentally touching it. So what I need help with is what in the world can I substitute for the "sticky stuff" that won't kill a bird!
