The goal of this activity is to introduce students to the variation that exists in a population of organisms. Students plant different seeds in a field with a gradient of sunlight. Their seeds survive the winter and grow into plants the following spring to reinforce the point that the evolutionary changes the students observe take place over many generations. In a second model, a plant produces seeds, some of which grow into plants that are slightly different from those of the parent plant. (Evolution Readiness Activity 2 of 10.)
