Activity Accordion
Big Idea (15 minutes)
Learn about the different features of smart hydroponic farming systems.
Take Action (43 minutes)
Students will build their own farming system with the Climate Action Kit.
We've provided 3 ways students may build the project to support scaffolding and differentiation in your classroom: 'Use', 'Modify', and 'Create'.*
Activity | Description |
---|---|
Use |
Students will follow a step-by-step tutorial to build & use their farming system. The goal is to help them develop a better understanding of its features without requiring actual coding. Success CriteriaI can:

Assessment Accordion
Use the following criteria to assess student learning. Students can:
Conversations
- Articulate the benefits and drawbacks of indoor hydroponic farming systems
- Explain the purpose of each smart component and building block in the main build (Use, Modify, Create)
- Explain the purpose of the different control structures (loops, conditionals) and variables in the smart farming project (Use, Modify, Create)
Observations
- Add comments to the code to demonstrate their understanding of each block (Use, Modify, Create)
Products
- Add comments to the code to demonstrate their understanding of each block (Use, Modify, Create)
- Add at least two visual or audio cues to the farming system that represent the different stages of watering and improve the user experience of the prototype (Modify, Create)
- Design their own prototype that satisfies provided criteria (Create)
