Growing Knowledge: A Hands-On Garden Science Unit
An Eight-Week Exploration of Soil, Sustainability, and Stewardship
This practical and inspiring unit allowed students to dig deep—literally and figuratively—into the science and rhythms of gardening. From soil prep to seed saving, compost to hydroponics, learners cultivated not only plants but essential life skills like patience, observation, and environmental stewardship.
Week 1: Preparation
The unit began with getting our hands dirty—clearing weeds, prepping soil, and cleaning garden beds. Students learned about the importance of healthy soil, proper tools, and the foundation every successful garden needs before planting begins.
Week 2: Planting
Students explored the art and science of companion planting, learning which plants are “friends” or “foes.” They designed garden layouts, considered seasonal planting needs, and made thoughtful decisions based on what grows well together—and what doesn’t.
Week 3: Composting
It’s not waste—it’s future soil! Students built compost bins, learned the importance of turning compost, and identified the “dos and don’ts” of composting. They studied decomposition and the powerful role of organic matter in enriching the earth.
Week 4: Vermiculture
Worms took center stage this week! Through vermiculture, students discovered how worm farming improves soil health, what worms can (and can't) eat, and how these tiny helpers play a big role in garden ecosystems.
Week 5: Fertilizers
Students performed basic soil testing and explored natural fertilizers like compost tea, fish emulsion, and worm castings. They compared chemical vs. organic methods and discussed how to feed plants without harming the environment.
Week 6: Pollinators, Pests, and Helpers
This week focused on identifying friends and foes in the garden. Students planted pollinator-friendly flowers, learned natural ways to deter pests, and discovered the benefits of bees, ladybugs, and other helpful visitors.
Week 7: Hydroponics
A look into innovative growing methods introduced students to hydroponics—growing plants using less water, soil, and space. Students explored how grow towers work and compared the pros and cons of soil-based vs. water-based systems.
Week 8: Harvesting
The final week celebrated the fruits of their labor. Students harvested produce, practiced seed saving, and learned how to give land a season of rest. The unit concluded with a shared feast, honoring hard work, community, and the beauty of the growing cycle.
From Seed to Sustainability
This unit gave students more than gardening skills—it rooted them in real-world science, ecological awareness, and a sense of responsibility for the earth. By growing their own food and caring for the soil, students gained a lifelong appreciation for nature’s rhythms and the joy of cultivation.
