Google has announced its 2018-2019 Science Fair winners.

A few details:

Participants are 13-18 years old.
The program is global.
179 prizes awarded.
The grand prize awardee receives a $50,000 academic scholarship.
There are travel based prizes sponsored by Lego, Virgin Galactic, National Geographic, and Scientific American.
The field is divided into global finalists, regional finalists, and state and territory winners.
There is an entry for each awardee which includes a summary, the question/proposal, research, method/testing and redesign, results, conclusion, about me, and a conclusion
The Grand Prize was awarded to Fionn Ferreira, Ireland. Here is the abstract:

This project investigates a new method for the extraction of microplastics from water using ferrofluid, a nontoxic magnetic liquid that consists of oil and magnetite (iron oxide powder). In the presence of water, the ferrofluid attracts the microplastics because of the nonpolar properties of both. I investigated this extraction method on 10 different types of microplastics. The concentration of plastics before and after was measured using a homebuilt spectrometer and a microscope. The results supported my hypothesis of 85% extraction.

What an incredible range of projects and approaches. Here is a small sample of the diversity: Averrhoa bilindi: A Natural Coagulant For Rubber Latex; Alteration Of Bicycle Handlebar Grips To Decrease Impacts As Measured By Penetration Into Ballistic Gelatin; An Electric Sole For The Foot
That Prevents Muscles From Shrinking In Children With Cerebral Palsy; and Digital Agriculture Module Designed To Harvest Tree Vibration For Energy.

I hope you take a look.
