domestic science

I'm a little stuck... Click here to teach me more about this clue!

'experiment' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'home perhaps?' is the wordplay.
'home' becomes 'domestic' (similar in meaning).
'perhaps?' becomes 'science' (I can't justify this - if you can you should give a lot more credence to this answer).
'domestic'+'science'='DOMESTIC SCIENCE'

'at' acts as a link.

Can you help me to learn more?

(Other definitions for domestic science that I've seen before include "Household skills" , "Cooking" .)

I've seen this clue in The Irish Times.
