Kids can learn about what makes colors.
Leaves change color when plants stop producing the green pigment, leaving the red or gold color.
In this activity kids will see how a single color can be made from different colors. If you don't have food coloring, water based markers will work. Color a spot in the center of the filter paper, than add drops of water. Children should be able to discover that purple markers actually have red and blue in the color. To use a straw, cut into pieces about 3 inches or 8 cm long.
