If you are going to grow seeds, put them in water on Friday to soak so they will be ready for students to prepare on Monday for growing. They will sprout early in the week, giving students more time to view the growing stage uninterrupted. Radishes and alfalfa sprout faster than beans, and if it’s out of season to buy garden seeds, a health food store that sells seeds and grains for sprouting and milling may carry radish, alfalfa, mung beans, wheat and corn year ’round.
