I crafted this lesson to make Renaissance art techniques accessible to a 2nd grade homeschool student. I now present it with full instructions and a web quest which should be valuable for all K-12 students of art or European history of the Middle Ages.
Although I did not mention him, Leonardo da Vinci is credited with bringing this technique to the fore. I do not have an art background with the exception of one drawing class in college, so what I have learned about chiaroscuro and pencil work I have gleaned on my own from the sources attributed. I want to mention the Web Gallery of Art in Hungary as a resource especially worthy of classroom and personal use.
One teacher may copy this activity for all students for one year, OR one homeschool family may copy it for all students for the duration of homeschooling.
