A guide to discovery of the forces at work in the world of plants. Through germinating seeds and varying their growing conditions, students learn by observation the different ways seeds germinate and young plants respond to moisture and light. Further experiments shed light on the manner of nourishment, respiration, and reproduction. The reader is given plenty to ponder since the text often poses questions without supplying answers. The life stories of the sweet pea, oak, ferns, moss, and mushrooms and an account of some of the forces plants have to contend with in their struggle to survive encourage students to continue to read and interpret their surroundings. An engaging introduction to botany for middle school and beyond.
