Go in the direction you would go to get to Lanayru Sand Sea. Instead of going to the Lanayru Sand Sea, go over to the Goron who has now made a hole in the wall that you can crawl through. This leads to Lanayru Gorge. The thunder dragon is there, but he's dead in the time period Link's in, so you'll have to go through a whole bunch of obstacles to resurrect him using a time shift stone on a mine cart.
There are three dragons in skyward sword. The first is located in Lake Florana. You must, however, complete the silent realm challenge before you can find her. You can find the silent realm location with dowsing.

you can find them in lanaryu desert
Use your dowsing ability to find the area where it is located. then use a bomb to destroy the cracked wall. The key will be there.
Game stop is where I got it
it is in the middile of the desert sea, and you have to use your dowsing ability to find it
You can find them in the silent realms or buy them from the moonlight merchant for 100 rupees.
Go to the graveyard at night, and roll into the grave closest to the tree.

It's in the Bazaar, near the items girl.
