Overview
Measure a society's wet waste and design composters sized to handle it.
Skills you will use
Safety
- Treat every culture as if it could be harmful: keep dishes sealed, never open them once grown, and soak them in disinfectant before disposal. Wash hands after each session.
Materials and tools
- Weighing scale
- Survey sheet
- Information on composter types and prices
Tools and software
Step-by-step roadmap
Start
You will finish with: a design proposal with sizes, costs and a daily routine.
- 1
Prerequisites
Nothing special to know first. Then collect the 3 items in the materials list.
- 2
Learn
Read up on waste systems: community, composting, waste. Your textbook chapter and one short video are enough.
- 3
Plan
Sketch the design, list every part with its price and decide how you will know it works.
- 4
Build
- Weigh the wet waste from ten households for a week.
- Scale up to the whole society.
- Compare three composting methods.
- Size the bins and plan the layout and routine.
- Estimate the cost and the compost produced.
- 5
Test
Run it ten times in a row. Note every failure, fix the cause and test again.
- 6
Document
Photograph each build stage, keep the circuit or drawing, and note what failed and how you fixed it. Report structure
- 7
Present
Demonstrate it working first, then explain how it works and what you would improve. Presentation structure
- 8
Publish
Share a short video, the parts list and the drawing or code so someone else can build it.
Expected outcome
A design proposal with sizes, costs and a daily routine.
