My groups first created their Alaskan snow-capped mountains using oil pastels, blending with baby oil and cotton swabs. As an added bonus, the room smelled great when we were done! Skies and seas were painted with watercolors and tempera. After these were dry, they added a splattering of white paint for their breaching whales. Orcas were drawn on a separate paper and then glued to their backgrounds. You can find another orca project here.
