In English, the verb was originally (and still is in the UK and most parts of the English-speaking world) spelt as "practise". The noun is "practice". In the United States, they have taken to spelling both the noun and the verb with a "c". I have no idea why they've done that. Maybe it's because they couldn't tell the difference between a noun and a verb? Crazy Americans!

Practice is a noun whilst "practise" is the verb.

They both have the same meaning, it's just that "practise" is the british way of spelling the word while "practice" is the American way.

They are alternate spellings of the same word. In the US, it is normally spelled "practice" and can be used either as a noun or as a verb. I can't comment on the British practice of using "practice/practise". :]
