This is a sweet and simple project we made at the preschool last week. Pine cone bumblebees. Bumblebees have been very busy in our autumn garden buzzing around our second harvest of raspberries, so bees have been on the children's minds. With a small pine cone and two maple tree seeds a piece of string and a stick to hang it from, the children made these cute bumblebees that float gently about as you move the stick. The older children were able to try tying the two knots that are needed to put this project together, but other than that, it was an easy one for all the kids to make themselves.
