Materials Science
ISEF category MATS · difficulty for high-school students: high
Structure, properties, processing, and performance of materials: metals, polymers, ceramics, composites, nanomaterials, biomaterials, and smart materials.
How it's judged
ISEF scores 100 points across five criteria:
- Creative Ability: 30 pts
- Scientific Thought: 30 pts
- Thoroughness: 15 pts
- Skill: 15 pts
- Clarity: 10 pts
What wins
- Synthesis and characterization of novel nanocomposites with improved mechanical properties
- Bioinspired material design mimicking natural structures (nacre, spider silk, bone)
- Novel polymer with tunable degradation rate for biomedical applications
- Phase change material optimization for thermal energy storage
- Self-healing material mechanism study with quantitative recovery characterization
Common mistakes
- Reporting only one material property without structure-property relationship
- Not characterizing material structure (XRD, SEM, FTIR) alongside performance
- Synthesis without yield and purity reporting
What you'll need
Depends on material class. Polymer synthesis: basic chemistry lab. Nanomaterials: centrifuge, UV-Vis spectrophotometer. Characterization (SEM, XRD, TEM) requires university materials lab.
Ethics & approvals
Human-subjects (IRB) approval is usually not required for this category. Vertebrate-animal (IACUC) approval is usually not required.
The novelty bar
A new material composition, a new processing approach, or a new structure-property relationship. Mixing commercially available materials without novel synthesis is not competitive.
