Science Fair Statistics 101: How to use statistics in your science project

The objective of this video is to help you use statistics in your science fair project for the 2025 Orange County Science and Engineering Fair (OCSEF). It uses a sample science project that follows the instructions in the OCSEF slide template for science projects. The results slide in the OCSEF template includes a graph of

2025 OCSEF Registration

Registration is now open for the 70th annual Orange County Science & Engineering Fair! Don’t wait to complete your Online Application to register your project – the first step of participation in 2025 OCSEF.

Ask a Scientist/Engineer

The Ask a Scientist/Engineer program is an opportunity for students, grades 6-12, to ask questions and receive guidance from a scientist or engineer about any aspect of their project. These are informal ONE hour virtual events starting at 4 pm on selected Saturdays. Students must register by the Thursday before the Saturday session they want to attend.

OCSEF Students are Thermo Fisher Junior Innovators Challenge Finalists

Society for Science announced that Jocelyn Mathew and Rhea Sreedhar are among the 30 finalists in the 2024 Thermo Fisher Scientific Junior Innovators Challenge – the nation’s premier STEM research competition for middle school students. Jocelyn, an 8th grader at Fairmont Private School (Anaheim Hills campus), entered her OCSEF project titled “Optimizing Microbiologically Contaminated Wastewater Treatment

OCSEF Academy 101 – Workshop Series

The Academy 101 workshop is an introductory course for students (grades 6-12) to learn how to conduct a science or engineering fair project. This FREE virtual workshop is a series of four Saturday sessions (1 hour each) designed for students with no prior science/engineering fair experience (click here for flyer). Each student must register by

16 and Bee

By: Anton G.Year: 2024School: Costa Mesa HighGrade: 9Science Teacher: Paul Serio Honeybee colonies are facing numerous threats, including pesticides, parasites, diseases, and the invasion of difficult-to-manage African Hybrid Bees (AHB). Introduced inadvertently in Brazil in the 1950s, these African bees have spread as far north as California, replacing many feral European honeybee (EHB) colonies. To address this growing

Filtration of Microplastics: Pumice versus Activated Carbon

By: Mohan G.Year: 2024School: Fairmont Private Schools, Anaheim HillsGrade: 6Science Teacher: Michael Morin Microplastics, tiny plastic debris less than 5 mm in size, have become a significant threat to our ecosystem. These minuscule particles, which can take hundreds to thousands of years to degrade, are now pervasive in our water, air, and marine life. Not only do they

Evalutating the Cost-Effectiveness and Productivity of Geoengineering Methods

By: Abhijith S., Neil D., Shrey M.Year: 2024School: Venado Middle SchoolGrade: 8Science Teacher: Eugene Hahn In the quest to combat global warming, geoengineering presents promising methods for reflecting heat radiation away from Earth. The project conducted by Neil, Shrey and Abhijith aimed to determine which of the two solar geoengineering methods, space mirroring or stratospheric aerosol injection (S.A.I.),
