I showed them an example which I had done which looked like a wiggly worm, an abstract line of curves which curled and crossed one another. I had painted my line with frequent color changes. My son said it made him hungry because it looked like a gummi worm. Each child could draw anything they wanted on their paper with their glue bottle. Then we put their pictures in a deep cookie pan and dumped salt on top until the glue was covered all over thickly. Then they were ready to paint right away.
I taught the children how to be gentle with the little brushes, and not to splay them out and scrub them on the watercolor cakes, which breaks the hairs. Some of them could remember that, and had the coordination to do it. Some weren't able to do it, yet. I think next time we paint we will practice stroking a pretend cat with our brushes.
Unless you are using liquid watercolors, teach the children to gently stroke the watercolor cakes with the brush with plenty of water until the pigments are dark and wet.
The reason is because when you touch the salt-covered line with your pigment-loaded brush, the salt will slurp up the paint. The more paint, the more vivid your painting. Here is a picture of a young artist softly tapping her salty drawing with the brush. I asked the children to tap on the salt as softly as they would tap the back of a ladybug with their brush, so that the ladybug wouldn't get hurt or even have to bend its legs.
The classroom was very peaceful, and the children seemed very content as they worked.
Aren't the colors luscious? I love the way the children used their colors! Incidentally, I removed all the black, brown, ochre, and beige watercolor cakes from the boxes to help prevent mud puddles from happening.
I wonder if the upper primary group would like this project, too?
