Full exit outcomes and Sustainable Development Goals for Level 10
Engineering & Design
- Design a part independently in Onshape CAD software and 3D-print it to solve a sustainability-linked problem (the "Design a Reusable Utensil Holder" pre/post challenge).
- Apply the full Engineering Design Process (NGSS HS-ETS1) through self-selected digital design and fabrication, without this level's alternative to a fixed team-role structure.
- Plan a solution visibly in CAD, producing a saved design artifact, before fabrication.
- Participate in structured "Share and Improve" peer critique rounds on an individual design rather than team-based building.
Science
- Apply high-school engineering design standards to a digitally fabricated solution (NGSS HS-ETS1).
- Investigate heredity or molecules-to-organisms content connected to a design problem (NGSS LS1/LS3).
- Explore a human-activity/Earth-systems theme such as responsible consumption (NGSS ESS3).
- Investigate IGCSE Biology 0610 content such as cell structure, DNA, or organ systems — the dominant science strand at this level, often via a physical model built alongside the CAD design.
Mathematics
- Apply IGCSE Core/Extended Number and Mensuration concepts to size a 3D-printed part accurately, such as fitting it in a school bag (Cambridge IGCSE Mensuration/Number).
- Use geometry, trigonometry, or transformations/vectors concepts to model a 3D shape in CAD (Cambridge IGCSE Geometry, Trigonometry, Transformations & Vectors).
- Apply high-school algebra, functions, or geometry concepts embedded in a CAD-based design task (Common Core HS Algebra, Functions, Geometry).
- Interpret statistics or probability from testing multiple print iterations (Cambridge IGCSE Statistics/Probability; Common Core HS Statistics & Probability).
Computing & Coding
- Model a physical part in Onshape, a professional-grade CAD platform, using precise dimensions and parametric design tools.
- Prepare and execute a 3D-print job on a Creality Ender-class printer from a completed CAD file — a full digital design-to-physical-object workflow.
Give and receive structured peer feedback through multi-round “Share and Improve” critique, working without a fixed team-role structure.
Recognize real health & life-science careers peaking again around 3D-printed biology models, such as Genetic Engineer, Cell Biologist, or Bioengineer.
Identify the Sustainable Development Goal connected to their build, themed around Health & Biological Systems.

Project 1: Cell Models
The first project of the level, as it appears in the guidebook. The full workbook is in the reader below where published.
A visually impaired student needs a better way to learn plant and animal cell structures, but flat images are hard to understand. You will design 3D cell models that can be explored by touch to make learning clear and inclusive.The problem, as printed in the workbook.
