Students learn about the parts of seeds and how seeds are dispersed. Students also learn about the life cycles of flowering plants and conifers.
Students learn how flowers and cones form seeds and how pollen is scattered.
By the end of fourth grade, students will develop an understanding of the characteristics of living things. Students plant radish seeds in two plastic bags of moistened seed started mix, and then one bag in a well-lighted place and the other bag in a dark place. For 10 days, students observe differences between seedlings grown under light and dark conditions. Students find that plants grown in the light are sturdier and have larger, greener leaves than plants grown in the dark. Students will complete Lab Manual pages 5-6 as they do the activity.
