5.0 (1 rating)
The "Growlight Garden Exploration" project for 5th graders aims to teach students about optimizing plant growth through experimenting with various light conditions in an indoor setting. By designing indoor gardens and simulating natural conditions, students gain insights into how different light spectrums affect plant growth, the essential roles plants play in ecosystems, and their contributions to the cycling of matter and energy. The project incorporates hands-on activities like plant adoption and light spectrum labs, culminating in model garden designs and a reflective essay on the role of plants in ecosystems.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we design an indoor garden that explores the effects of different light conditions on plant growth while simulating the natural environment and understanding the role of plants in the ecosystem?

Essential Questions

Supporting questions that break down major concepts.
  • How does the availability of light affect the growth of different plants?
  • In what ways do plants depend on air and water for their survival and growth?
  • How can we design an indoor garden that mimics natural environmental conditions for plant growth?
  • What roles do different parts of the plant play in the growth process?
  • How do plants fit into the larger ecosystem and contribute to the cycling of matter and energy?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Students will develop models to describe the cycling of matter and energy within an ecosystem using their indoor gardens.
  • Students will analyze and support arguments about plant requirements for light and how different light conditions affect plant growth.
  • Students will design and construct an indoor garden that mimics natural environmental conditions to support plant growth.

NGSS

5-LS-2.4
Primary
Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.Reason: The project involves designing indoor gardens simulating an ecosystem, where students can observe and model the movement of matter between different ecosystem components.
5-LS-1.1
Primary
Support an argument that plants get what they need for growth chiefly from air, water, and energy from the Sun.Reason: Students are investigating plant growth under varied light conditions, directly relating to how plants use light as energy from the Sun.
5-PS3-1
Secondary
Use models to describe that energy in animals’ food was once energy from the Sun.Reason: Understanding how energy flows in an ecosystem begins with recognizing the role of plants as converters of solar energy, which is fundamental to indoor gardening projects.
5-ESS2-1
Supporting
Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and atmosphere interact.Reason: The indoor garden project encapsulates how different environmental spheres interact, especially focusing on air, water, and light.

Entry Events

Events that will be used to introduce the project to students

Pet Plant Adoption Challenge

Each student adopts a 'pet plant' to care for and observe under assigned light conditions. The classroom becomes a live research facility, as students document their plant's growth and share insights, fostering a personal connection and real-world experimentation experience.

DIY Light Spectrum Exploration Lab

Introduce students to a hands-on lab where they can experiment with different light spectrums to see immediate effects on small plants. This hands-on activity stimulates curiosity about the role of light in plant growth and challenges students to connect these observations to their upcoming projects.
