In this engaging and fun kit, students learn how to differentiate between plant food stored as a simple sugar and food stored as a starch. Using a step-by-step procedure, students first dissect the seeds, and then treat them with reagents. This helps to determine the quantity and location of the sugar and starch. The individualized, open-ended worksheets provide additional investigations for student exploration.
