I did a similar project last year with 5th grade that used blue and purple hues to create a glowing moon. I saw this one on Pinterest and just had to try it with my 5th graders! This project is great for teaching painting techniques, using just the right amount of pressure to create thin lines. Students have a tendency to smash their brushes onto the paper to get as much paint out as they can before dipping the brush again! I try to encourage them to dip their brush as often as they need to in order to make smooth lines.
