National Award Schemes?

[BestZebbie]

I'm wondering if there are any other award schemes that are similar to Crest Star or Arts Award Discover but in other subjects?
Where you do a few weeks worth of project and write off for a certificate about it, suitable for the first few years in primary school?
I'm also aware of the library summer reading scheme and obviously there are loads in sports (were sports running at the moment) and Scouting/Guiding etc, but I was looking more for an academic thing that we could potentially do higher levels of in future years as well. Surely there must be one in maths somewhere?
