Color mixing on coffee filters is a fun introduction to what happens when those primary colors mix together!
Multi-media art idea: crayons, watercolour resist, and then print-making with paint over taped letters on individual canvasses. Only 20 letters in this quote, so would have to expand in some way for one per student.
