To add to a study of plants or to use while teaching about scientific observations grow your own grass people! Buy a small package of grass seeds, styrofoam cups and soil and have students each plant their seeds in the cup. As the grass grows have students keep an observation log of the growth progress. When the grass is long enough, have the students decorate their cups to make grass people! **Add twisty ties to allow students to put the "hair" in to pig tails.
