Big Science Day

Big Science Day 2018

Welcome to Big Science Day at Seisen International School

The Big Science Day is an annual event where students from Grades 8, 10 and 11 proudly display their unique science projects to fellow students and professional judges, showing their wonder and appreciation for the world around us through their imaginative scientific processes in which they produce their final product. Those with the most outstanding projects will be presented with an award in which they can choose what educational material they want to use their award for. Come and vote for your favorite science fair projects from our students!

Also, don't forget to check out our video from last year's event below and browse the tabs on the left to visit galleries from previous events and the winners in the past.
