Science teachers have been told to keep their experiment exciting if they want to motivate young people to study.
The secretary of state for education has said schools need their children to enjoy the experience of studying so much they go on to study in more depth at secondary school level.
Teaching in the UK teachers should make experiments at primary school level "fun and challenging and make learning come alive," the minister told the Independent.
Mr Balls was speaking ahead of the Times Cheltenham Science Festival, which runs June 3rd to 7th, and noted that science "is one of our country's great strengths and the jobs of the future are increasingly going to be hi-tech and science-based".Teaching assistants
who have been helping give lessons on evolution could find some excellent information from the festival, as it will be looking at Charles Darwin's controversial work as well as celebrating the international year of astronomy.
