This lesson is really rewarding for the kids because drawing a mason jar symmetrically correct is difficult. However, the steps to the jar are easy to follow and there are several full page reference drawings included in this lesson for the kids to use as visual references in their observational drawing skills. It’s also a really fun lesson because the kids use white chalk for the mason jar since this is a night sky composition. They use the white chalk both for the jar and to show value as an  element of art. It’s also really fun to make all the plants in and around the jar and the fireflies in and outside the jar!
