Here's a simple crayon and watercolor painting idea that was inspired by an illustration on a stock art website.
PREP: I've found it helpful to trace 9 large circles very lightly in
pencil on watercolor paper to use as a guide.
1. Students
to make an "X" in the middle of each circle with a white crayon, and then a horizontal line
through the middle so their flake will have 6 legs. After that, they
may add dots or arrows to each. They must press very hard and draw
slowly to leave a lot of crayon on the paper.
2. Once you are certain
that there is a snowflake drawn in the middle of each circle, pass out
lots of liquid watercolors. Students fill in each pencil circle
with paint, the snowflake will “magically” appear. A simple project
with beautiful results, I think.
