Despite coronavirus, many chemistry competitions are still running this year

Science competitions are a great way to engage students, build on their practical skills and test their knowledge. Competition teaches the importance of teamwork, success and failure. You can also use competition materials in your lessons, as homework, or as part of an extracurricular science club.

Most competitions have changed to a virtual format this year. Nevertheless, the following competitions are a great way to motivate students, develop their practical projects and written skills and even be in with a chance of winning fantastic prizes.

These competitions have been ordered by closing date. Last updated: 18 May 2021.

UK Junior Water Prize

Age: 15–20
Opens: now
Submissions close: 28 May

The UK Junior Water Prize (UKJWP) is a competition aimed at solving environmental challenges with a link to water. Students identify an issue and find a practical and innovative solution through research and experiments.
