Your kid can paint watercolor on watercolor paper, and then sprinkle salt while the painting is still wet. Let it dry, and then gently brush the salt off.
Have your kiddo describe what they observe. What happened where the salt was? Why do you think it did that? (The answer is that salt absorbs moisture, so it pulls the water towards itself, leaving more color around the salt after the water evaporates).
Even the littlest kid can move a brush around on paper! Use watercolor paper, watercolor paints, and a wide brush. If your child is like mine, they’ll love to mix colors together until everything is brown… an easy fix is to give them color choices that mix well together. It can also be helpful to paint one color at a time, letting the paint dry in before painting the next color.
-Matte one (or more) of your child’s paintings and hang it up in their room (or anywhere in your house!). You can even have them paint in colors that compliment the colors in their bedroom.
-Matte/ frame a painting and give it as a gift
–Watercolors are a great way to learn about and discover how colors mix together to make other colors. Use two primary colors to create a painting that has both colors, as well as the secondary color created when they overlap.
