I can't take credit for this one..on the advice of a fellow homeschooler I rented from our library an art book entitled "Discovering Great Artist" by Mary Ann F. Kohl and Kim Solga. We started the first lesson today and I have already fallen in love with this book.
The first lesson is on the painter Giotto (1266-1337). He made his own paint from a mixture of dried berries, clay or mineral, egg and water. After a brief description of his life and work, there is an art project based on his style of painting. The girls and I grounded chalk into a fine powder then added yoke and water stirring until we made a smooth vivid paint. The girls loved this project and even my littlest one got in on the act!
