Purpose

Children investigate the question, How can we build and care for a garden that uses water instead of dirt?, by designing and tending a simple hydroponic garden together. They learn that living things grow and have needs, compare how plants use water, light, and care, and practice habits that help the environment and protect other living things. With support from a neighborhood nursery, students observe seedlings, use gentle plant care, and work collaboratively to solve problems and explain how their garden reduces impact on land and resources. The experience builds toward the Little Growers Gallery and a small garden showcase where each child shares what they learned and how they helped their plant grow.

Learning goals

Students will build and care for a simple hydroponic garden to explore what plants need to grow, how living things change over time, and how people can help the environment by using water carefully and caring for living things. They will ask questions, make observations, compare plant growth, and use evidence from their class garden to explain how plants and people change environments to meet their needs. Students will practice collaboration, listening, kindness, and safe habits as they work with classmates and a neighborhood nursery partner to prepare for the Little Growers Gallery. By the final garden showcase, students will clearly answer, “How can we build and care for a garden that uses water instead of dirt?” share one thing they learned, and describe how they helped their plant grow.

Standards
  • [California] K.1.5.P - Identify practices that are good for the environment, such as turning off lights and water, recycling, and picking up trash.
  • [California] K-ESS3-3 - Communicate solutions that will reduce the impact of humans on the land, water, air, and/or other living things in the local environment.
  • [Next Generation Science Standards] K-ESS3-3 - Communicate solutions that will reduce the impact of humans on the land, water, air, and/or other living things in the local environment.
  • [California] K.7.2.M - Describe positive ways to show care, consideration, and concern for others.
  • [Next Generation Science Standards] K-ESS2-2 - Construct an argument supported by evidence for how plants and animals (including humans) can change the environment to meet their needs.
  • [Next Generation Science Standards] K-ESS3-1 - Use a model to represent the relationship between the needs of different plants or animals (including humans) and the places they live.
  • [California] K.8.1.M - Encourage others when they engage in safe and healthy behaviors.
  • [Next Generation Science Standards] LS.2.D - Social Interactions and Group Behavior
  • [Next Generation Science Standards] LS.2.C - Ecosystem Dynamics, Functioning, and Resilience
  • [California] K.1.1.G - Explain that living things grow and mature.
Competencies
  • Effective Communication - Students practice listening to understand, communicating with empathy, and share their learning through exhibiting, presenting and reflecting on their work.
  • Collaboration - Students co-design projects with peers, exercise shared-decision making, strengthen relational agency, resolve conflict, and assume leadership roles.
  • Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.
  • Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
  • Content Expertise - Students develop key competencies, skills, and dispositions with ample opportunities to apply knowledge and engage in work that matters to them.
  • Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.

Products

Students will create a class hydroponic garden system, plant care tools such as picture watering/check charts, and simple observation pages with drawings that show how living things grow and what plants need. In small teams, they will make solution posters or labels that share ways people can care for plants, save water, and help the environment, connecting their work to the essential question, “How can we build and care for a garden that uses water instead of dirt?” With support from the neighborhood nursery, children will prepare healthy seedlings and gentle plant-care routines, then present their work in the Little Growers Gallery. By the end, each child will contribute to the final garden showcase by displaying the system, sharing one thing they learned, and telling how they helped the plant grow.

Launch

Begin with a mystery garden invitation: show children a healthy plant in soil and a plant growing in water, then ask, “How can we build and care for a garden that uses water instead of dirt?” Invite a neighborhood nursery partner to bring seedlings and simple hydroponic materials so students can touch, observe, and practice gentle plant care in small teams. Students taste or smell a kid-safe herb or lettuce, notice roots, leaves, and water, and make simple predictions about what plants need to grow and how people can help living things while using resources carefully. Close by introducing the class challenge: build a small water garden to share at the Little Growers Gallery, where they will present their system, tell one thing they learned, and explain how they helped their plant grow.

Exhibition

Host a Little Growers Gallery where children display their hydroponic gardens and welcome families, school staff, and the neighborhood nursery partner. Each child shares one thing they learned, shows how they built and cared for the system, and answers simple questions such as how water helped the plant grow and how they helped the environment. Include a short “gentle gardener” demonstration so students can model safe, caring plant habits and encourage visitors to try them too. End with the small garden showcase celebration, where visitors leave kind feedback and students proudly tell how they helped their plant grow.
