SEE WHAT COLORS OF LIGHT ARE BEST FOR GROWTH It should be interesting to see if colors make a difference in plant growth. In this box with gravel on the bottom and potting soil on top, we'll plant some grass seeds. Won't it be nice to have some lawn in our classroom? Does anybody have a tiny lawn mower, so we can keep it nicely trimmed? After the grass seeds have germinated and we see a little green on top, we will put some cardboard walls into the box, making four different patches of grass. We want to put walls up around the edges of the box as well, and all the walls should be about three inches tall above the soil. We will use colored cellphane (gift-wrap) to give each section a different color of light. One section will have red, another will have blue, and a third section will have green. We'll put clear plastic wrap over the fourth section. We'll keep track now, and see which section grows best. We want to see how tall the grass is in each section, and decide if they are all the same, or if the grass gets taller in one section than in the others. We also want to check to see if the blades of grass in one section are wider or fatter than those in the other sections. Let's remove the cellophane for a short time so that we can compare the colors of the grass in the different sections, as well. What color is the favorite of most young people? Does red appear to be the favorite color for the grass?  Any problems with this page? Send URL to
