Quote: YEs, you have it perfectly.
Art can be hands in paint and then on paper; art can be paper on a styro meat tray, a table sppon of blue tempra and a tablespoon of red, and roll a marbles around. ( let child pick from several colors.) DId both of these in preschool classes as an aid.
Making jello can be science-- mixing colors like something blue and something yellow, and liquid and solid. Simple on one hand or more comples on another.
