Overview Accordion
Learning Goals
- Describe at least three benefits of seaweed farming
- Identify risks of seaweed farming, such as marine animal entanglement and ecosystem disruption
- Build a seaweed farm model that:
- uses an accelerometer sensor to detect unusual movement in the ropes
- triggers a radio alert to the farm technicians when excessive movement is detected, so trapped animals can be released
Preparation Accordion
Materials
- Climate Action Kit
- micro:bit V2 (x2)
- Computer with access to Microsoft MakeCode
- Craft supplies:
- string/yarn/elastic bands to represent farm ropes
- construction paper for seaweed
- scissors
Get to Know the Content
- Make sure you've completed our 'Getting Started with the Climate Action Kit' course
- If it has been awhile, review the micro:bit features used in this lesson:
- Review the lesson
- Explore thinking routines like “See, Think, Wonder” from Project Zero to encourage observations and reflections
Activity Accordion
Big Idea (15 minutes)
Students will:
- Explain how seaweed farms provide food and shelter for ocean animals
- Identify how seaweed absorbs carbon dioxide to help fight climate change
- Discuss risks, like animal entanglement and sunlight blockage, and how technology can help mitigate these issues
Take Action (60 minutes)
Students will use the Climate Action Kit to design, build, and code their own seaweed farm model. The model will detect movement and send alerts if an animal gets tangled in its ropes.
We've provided 3 ways students may build the project to support scaffolding and differentiation in your classroom: 'Use', 'Modify', and 'Create'.*

Assessment Accordion
Use the following criteria to assess student learning. Students can:
Conversations
- Can students explain how seaweed farms benefit the ocean and people on land?
- Are students able to communicate the risks of seaweed farm and explain how technology can help solve these problems?
- Can students explain how the sensors and alerts work in their model? (Use, Modify, Create)
Observations
- Do students methodically test and debug their models? (Modify, Create)
Products
- Students annotate their code to explain how it work (Use, Modify, Create)
- Students add their own events to trigger output (Modify, Create)
- Student-created models meet the design criteria outlined in the lesson (Create)
