Description: After learning about Henri Rousseau's art and how he liked to hide objects in his artwork, the class drew animals using a blue colored pencil. We actually drew our animals upside down and practiced contour drawing (copying the shape). This allowed us to visualize the image as lines and shapes put together instead of an animal we were trying to recreate. After the animal was drawn, we took our warm-colored crayons and drew several patterns over the animal. This hid the animal. To discover the animal, we created "Ruby Red Glasses," using red construction paper and red transparent plastic. When you look through the glasses, the red filter cancels out the warm patterns and it is easy to see the animal left behind!
Extension Activity: There are many ways I could use this concept in my classroom. My students could send hidden messages by obstructing the message with patterns that require the special glasses to remove. This process could also be used to hide answers to different homework questions. It would be a fun way to encourage students to get their work done so they could use their glasses to correct their work.
