Seeds in Nature at Juan Cabrillo

Today’s class was dubbed “The Seed Laboratory.” Everything we talked about was related to SEEDS.

After drawing the three parts to a seed (coat, food and embryo) and remembering how a seed grows, we talked about how plants produce more seeds so they can grow again. The kids instantly knew that seeds develop in a flower (example: sunflowers) but it took them a minute to realize fruit was the other source of seed development. I held up a watermelon from their garden, split in two, to show them an example. “I knew that!” one kid declared, beaming. I was glad to see dots connecting in the kids’ minds. 🙂

I brought some sprouted red beans and let the kids find all three parts: the red outer coat, the white fleshy food inside and the tiny embryo where the leaves would grow.

Then we went on a scavenger hunt in the garden to find seeds. Several lettuce plants were bolting so this was a great opportunity to show them how lettuce (a vegetable) makes seeds. We also watched some bees pollinating the flowers (which helps the flower make seeds!).
