We wrote a grant at my school to build a butterfly habitat. Each class was given butterfly larvae to watch. When they turned into butterflies they were put into the butterfly sanctuary outside the Library. Interest was high on the subject of monarch butterflies! My second grade students first drew the butterflies in pencil and colored with orange, black, and white crayon. The next week they used oil pastels and watercolor paint for the background. The paintings were beautiful in the hallway next to the Library and I ended up with a great lesson on teaching symmetry in nature.
