EXPERIMENTS WITH COLOR
Prism (Secure glass prism from kindergarten store or from some candelabra you may have at home)
Place in sunlight and let child observe colors and the order in which they appear; always in the same order—the cold colors at one end, the warm ones at the other. Let the little child try to catch and hold the lovely "light-bird."
Pigments (Water-color paints, glasses of water)
Dissolve a little red, yellow and blue paint in three separate glasses. Then, by mingling these—the primary colors—show how the secondary colors—orange, green and violet—may be obtained.
Transparent Papers
Get at a kindergarten store the transparent papers and isinglass used in color work. By overlapping one upon another different hues may be obtained. This may be done also, though less effectively, with colored tissue papers; but these are not so pure in tone.
Color-Top
Color tops may be procured at kindergarten stores. With the top come paper circles, of standard colors, with their tints and shades, giving a great variety. These are so slit that by placing two or more on the top according to directions and revolving the top, any tint or hue may be mathematically produced.
If the child has made his own button-mold top, let him cut circles of white paper and slip them over the axis of the top. Make a dab of color here or there on the paper with paint or chalk. Whirl around and observe the effect. This will lead up to a better understanding of the above-mentioned color-top which is manufactured by the Milton Bradley Co.
