Legislative Branch - Why did the framers give stricter qualifications and a longer term of office for Senate? What was the reason to give the House members such a short term in office?

In order to have a successful government, you need stability (which is guaranteed by the Senate with the longer terms, and the qualification demand ensures that the stability will come with quality) but also innovation, which is guaranteed by the House: the shorter terms are likely to introduce new people with new ideas into the congress.
