Glycerin Duration On Flooring Materials using Dunstan’s Test

From 2018, 9% of adults have said they occasionally vape, and from 2019 around 27.5% of high school students use vape products, both groups in the U.S. According to the FDA, 1 million youth e-cigarette users use it daily, giving an idea of how common vaping is. Tam’s OCSEF project sought to inquire about the

Effectiveness of Different Adaptive Image Steganography Methods

By: Sydney B.Year: 2021School: Portola HighGrade: 10Science Teacher: Jeralyn Newton Steganography is the practice of concealing secret information inside of an inconspicuous carrier object. Sydney explored different methods of concealing written messages in the pixels of a digital image. Writing multiple computer programs that each concealed a given message in a picture, Sydney then tested

Corrosion of Metals

By: Rakshana S.Year: 2020School: Lakeside Middle School, 8th gradeDivision: JuniorAdvisor: Mrs. Feng All structures we see outside are usually made of any type of metal, mostly steel. When it is exposed to any liquid and oxygen it creates a process called iron-oxide also known as rusting. Rust can change steel into different material, even material
