On a quiet back street in Vista sits a small school vegetable small garden. Crafted by K-5 students at Casita Center for Technology, Science and Math. this collection of vegetables is not only a gardening lesson, but also lesson in history.
Assistant Principal Tammy Lee and her talented staff have researched a project in one of the 15 beds, fondly known as the Three Sisters Garden, which features corn, beans and squash.
A lesson in Native American culture
Native American gardens can teach us about the Iroquois, showing us a “system adapted by the culture that experimented with crops that respond to each other.” This lesson came from just one of the many activities featured in the Cornell University Garden-Based Learning Program.
If you and your children would be interested in creating a home-based garden program this summer, and would like to create The Three Sisters Garden, visit the site (gardening.cals.cornell.edu) for planting instructions, harvesting and related science activities. This site is a great resource.
Casita Center cooks up a storm
At the Casita Center in Vista, the outdoor garden activities are part of the STEM program, which integrates hands-on learning, imagineering, sustainability, communications and core subjects.
According to Lee: “Our students experience the full gambit of producing food when they participate in cooking projects with kitchen lab instructor Grace Gray. … The students participate in nutrition lessons each week, such as cooking with the Three Sisters Garden or making guacamole! Another favorite is making pizza with toppings of fresh tomato, basil and peppers.”
