CSEF projects, 2002–2026

Every California Science & Engineering Fair project Fairfolio holds: 17,387 entries across 24 years, with the abstract, category and awards the fair published for each one.

CSEF coverage: available historical abstracts for 2002–2019; award-listed projects only for 2021–2025, without abstracts and with explicit labels where titles were not published, except that most 2023 winners carry the abstract from CSEF's archived public showcase; public showcase abstracts for 2026. The 2020 fair was canceled.

Years

Category breakdown

Counts cover every year of this fair and use its own category labels, exactly as the source published them. Each one links to that category's CSEF projects.

Ready... Set... Ferment!

Chemistry

Objectives/Goals My hypothesis is that there is a relationship between the initial sugar level of grapes and the ultimate alcohol level of wine. I believe the ratio of sugar percentage by vo…

CSEF · 2003

Ripening Bananas with Ethylene Gas

Materials Science (Junior Division Only)

Objectives/Goals The objective of my experiment was to see if different environments will accelerate or decelerate the ripening process of a banana. Also, what effect temperature and/or ligh…

CSEF · 2003

Robot Efficiency Test

Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Objectives/Goals Our project is to test which robot can move more efficiently on both carpeted and smooth surfaces. We are testing out Robot A with legs and Robot B with wheels. We will vary…
