Youth Science London exists to support, encourage & operate activities that promote the advancement of science and technology among students of all ages and abilities: to benefit both the educational systems and the community. We run two major events: (a) The Thames Valley Science & Engineering Fair and (b) The London District Science Olympics. We used to be known as the London District Science and Technology Fair. After 43 years, we decided to change our name. We are looking forward to another 43 years of success
