If you're between 11 and 18, live in the UK and have just completed an interesting maths, science, engineering, or technology project, then why not enter the National Science and Engineering Competition?

The best entries will be invited to present their project at the Big Bang: UK Young Scientists’ and Engineers’ Fair, in Manchester in March 2010. You’ll have your own stand to show off all your hard work to over 13,000 scientists, engineers, students, parents, employers, teachers and celebrities. Plus you may even be chosen to face a VIP panel in the competition finals.

There are over £50,000 in prizes up for grabs, including cash awards and trips abroad. And entrants in the senior category could be crowned the UK Young Scientist of the Year or the UK Young Engineer of the Year.

It doesn't matter if your project has already been entered into another competition, you're still eligible, but hurry up, the closing date is October 30th!
