Obama on Science Fairs

“We need to teach our kids that it’s not just the winner of the Super Bowl who deserves to be celebrated, but the winner of the science fair. We need to teach them that success is not a function of fame or PR, but of hard work and discipline.” President Obama, State of the Union Address 25 January 2011

Founded in 1971

The first London District Science & Technology Fair was held in the Faculty of Education building in 1971.   Our name was modernized to the Thames Valley Science & Engineering Fair in 2013.
