🌱 Planters for Social Enterprise

🧭 Unit Overview

Statement of Inquiry:

Social entrepreneurs can innovate and influence communities.

Key Concept: Communities
Related Concept: Innovation
Global Context: Fairness and Development (Social Entrepreneurs)
Technology Focus: 3D Modeling with Onshape


🎯 Project Brief

You will design and 3D print a self-watering planter that could be used by someone in your community. Your challenge is to create something innovative, useful, and appealing, guided by the principles of social enterprise.

Your final product will:

  • Be designed in Onshape
  • Be 3D printed
  • Include testing or simulations of how it functions
  • Be evaluated based on Criterion D

πŸ“ Assessment: Criterion D - Evaluate

You will evaluate your design based on how well it meets your design goals. You will not be able to use it with a live plant yet, so your evaluation will focus on the design and print quality, and what you observed during testing.

Use this rubric to guide your final evaluation of your 3D-printed planter.

Focus on how well it meets your design goals and what you learned during testing and printing.


βœ… Level 1–2 (Limited)

You:

  • Briefly describe your testing (e.g., β€œI checked if water stayed in”).
  • State if the planter worked or not, with little detail.
  • Do not include much evidence or explanation.

πŸ’‘ Example:

β€œI tested the planter by putting water in it. It printed okay.”


βœ… Level 3–4 (Adequate)

You:

  • Describe a basic test (e.g., water test, size fit, stability on surface).
  • Outline how well the printed planter met some of your design goals.
  • List at least one way your design could be improved.
  • Briefly explain how your planter could be useful to someone.

πŸ’‘ Example:

β€œI poured 100ml of water into the planter. It held the water, but some leaked.
I think I should make the walls thicker. It could help people grow herbs.”


βœ… Level 5–6 (Substantial)

You:

  • Describe at least one relevant test (e.g., volume capacity, balance, water retention) and share your results.
  • Describe the success of your design based on testing and your original success criteria.
  • Suggest specific improvements, based on what you observed during testing or printing.
  • Describe how your planter design could help people, based on its features and purpose.

πŸ’‘ Example:

β€œI tested the weight and balance. The planter tipped over when filled.
It meets the size goal but not stability. I would improve the base width.
This planter could help window gardeners grow lettuce with little space.”


βœ… Level 7–8 (Excellent)

You:

  • Describe detailed and relevant testing methods (e.g., volume tests, stability checks, material strength, peer review) that give accurate data or observations.
  • Explain clearly how your planter met or didn’t meet each success criterion.
  • Describe specific, thoughtful improvements, based on your testing, printing process, or peer feedback.
  • Explain in detail how your design could impact the user or community, based on its features and design purpose (even if not yet used with a plant).

πŸ’‘ Example:

β€œI tested water capacity (held 220ml, goal was 250ml), and checked that it fits a 6cm plant pot.
The print was successful but the walls were too thin. I would increase wall thickness and add a water-fill indicator.
The planter is designed to help students grow herbs in dorm rooms with limited time and space.”

Lesson 4: Advanced Onshape Tools

Learning Goal: Learn to build complex shapes (e.g., water reservoirs).
Activities:

  • Complete the β€œSelf-Watering Planter” exercise
  • Add: shell, water cavity, drainage hole, wick hole

Tutorials:

Journal Prompt:

  • What features did you add to make it self-watering?
  • What challenges did you face in modeling?

Lesson 5: Start Final Model

Learning Goal: Begin building your final planter model.
Activities:

  • Use your sketch as a guide
  • Start sketching and extruding your final design in Onshape

Journal Prompt:

  • What part of your design did you start with?
  • How did your success criteria guide your modeling?

Lesson 6: Continue Modeling

Learning Goal: Refine your model, adding detail.
Activities:

  • Add drainage, reservoirs, overflows, etc.
  • Use tools like shell, fillet, extrude remove

Journal Prompt:

  • What did you modify today?
  • How is your planter becoming more functional?

Lesson 7: Finalize Model & Export

Learning Goal: Prepare your design for 3D printing.
Activities:

  • Final checks (wall thickness, printability)
  • Export as STL for printing

Journal Prompt:
