SARSEF Science and Engineering Fair

95,000 K-12 students in S. AZ currently participate in SARSEF, conducting research projects to be considered as a representative of their school. The top 2,000 projects and 6,000 students will advance to come to a weeklong celebration of their achievements and further competition at the Tucson Convention Center.

Each year, over $100,000 in awards,trips and scholarships are awarded, thanks to our community support. Top HS students move on to international levels of competition. Our success rate at international competitions has been four-times the national average for the past 17 years now!!! This is unparalleled and SARSEF is often asked, “How do you do that?” We answer – it is thanks to our community that we are able to offer our services to children as young as five years old. Most Fairs do not do this. Our students have many years to develop their skills here in Southern Arizona, giving them an overwhelming advantage both locally and globally!

Annalisa’s amazing Environmental Engineering project is titled “Investigating How Water Vapor Emission Impacts The Temperature Of The Troposphere” 

“This project measures the effect of additional water vapor on temperature throughout a model of the troposphere. The project was done in an attempt to uncover whether or not the water vapor produced by human transportation and industry is effecting global warming along with carbon dioxide. A delta of the data does suggest that water vapor could be a reason we are seeing a gradual change in the earth’s climate. This project is important because it can raise awareness that everything can impact the environment even stuff that is harmless to us like water vapor, and will encourage more experiments into how the high temperature water vapor produced by industry is effecting our climate, weather and atmosphere.”
