This week, the children are experimenting with color mixing using liquid water color and water.  They call it “magic.”  Three year olds do not have much experience focusing on specific characteristics of objects.  Tools (such as magnifiers, lenses, and eye droppers) can help them attend to a particular object or specific aspect of an object. A simple science activity like this one can provide minutes of fun and wonder.  What you need:  a glass jar, eye droppers, liquid paint or food coloring or primary colors (red, yellow, and blue).
