Third grade students at Addison Elementary School in Palo Alto have been busy tasting, squishing, and saving the seeds of heirloom tomatoes while participating in the Life Cycle of a Tomato lesson. This lesson took a year off our schedule as we moved it from second grade, and adjusted it to fit the third grade NGSS standards. Students who participated in part two of the lesson this week enjoyed rinsing their seeds, and observing the impact of the yeast that had removed the gelatinous seed coats from the tomato seeds. Now the seeds must rest in a cool, dry place over the winter, so that they can be planted in the warm spring. Such a wonderful process for the students to participate in firsthand!
