Learners write or draw with white crayon on white paper. They look and feel to detect their marks on the paper. Then, learners paint over their paper with watercolor paint. The paint wets the paper except in the areas of the crayon marks, thereby revealing their writing or drawing. Learners discover that the wax resisted the colored paint because wax and water are not miscible, they don't mix together. Extensions of the activity show learners fabrics which are dyed using a wax-resist process called batik. This activity is currently used in the Nature of Matter and Everyday Chemistry Units in OMSI's Chemistry Lab. Cost estimates are per 100 learners.
