Nrich for science?

[Moonwatching]

I've seen lots of positive recommendations here for Nrich maths. And having had a brief look over the website, it looks like I'll be using it a lot.

Does anyone know of anything similar for science? Thanks.

Thanks Mrz. That looks great, just the sort of thing I'm wanting.
