Here is an easy-to-present set-up for a fundamental Montessori exercise. Cover the spectrum of the four basic tastes (bitterness, saltiness, sourness, and sweetness) with diluted bitter chocolate or almond extract, lemon juice, salt water, and sugar water. The varnished hardwood tray (10" x 4" x 1") has four pairs of ½" deep insets to hold the 1-ounce bottles. Tray edges extend for easy carrying. Color-code the matching pairs with adhesive dots for “control of error.” We use amber glass so the color of the liquid is not visible, and glass droppers because they clean easily. Ages 3½ to 6.
