Look at the ruler of that house. For instance, let's say 9th house. Mine is Gemini, so look at Mercury and its aspects. That will tell you more about 9th house activities

I highly recommend Howard Sasportas and his book about the houses. Let me go dig up a link. The Twelve Houses, that's what it's called
