Besides constructing their own lab equipment, students compile a complete written and visual record of growth, graph daily height and weight gains, study how leaves photosynthesize, examine the role of cotyledons in plant development, learn to distinguish monocots from dicots in flowering plants, and much more! 20 Lessons for late elementary and junior high students.
