Budding scientists and engineers have a chance to beat their rivals in a UK competition.

Pupils from Watford Grammar School for Girls have been selected to compete at the finals of The Big Bang UK Young Scientists and Engineers Competition.

A team of three who took part in a project investigating how much calcium carbonate is in an egg shell, while pupil Emily Nicholas was also chosen for her individual project about how microwave radiation affects different life forms.

Beth Elgood, director of communications at EngineeringUK said: "The teams really impressed the judges with their project and we’re excited to see how they do at the finals at the fair.

"Going into its tenth year in 2018, The Big Bang Fair continues to be a great source of STEM inspiration for young people, representing an amazing opportunity for young visitors, their teachers and parents to get hands-on with a wide range of activities, workshops and shows, and engage in meaningful career conversations with professionals, all designed to bring classroom learning to life and inspire the next generation."

The competition finals take place at Birmingham's NEC in March 2018.
