This was a super messy project but well worth it, in my opinion!
I found the lesson HERE on the Elle & Lou blog and it gives great directions.
Instead of charcoal, we used chalk pastels for the background
Grade 6 students started out by tracing a circle for the moon, then blending different dark tones of chalk pastel (including black) to create a moody night sky.
The desks (and floor! and students!) were covered in chalk pastel!!
The next class students drew on a tree branch- this was really difficult for alot of them! I was actually surprised- even after I demonstrated it for them, quite a few struggled, so next time I teach this I will have them draw a practice branch first. Then they painted the branch using black tempera paint.
For the final step, they highlighted the tops of the branches with white chalk.
