My RES will do that (dip his head) especially in the summer, when he's getting too warm and wants to cool off a bit. I've seen him basking with just his head in the water. When he gets too warm, into the water he goes.
Is the scratching accompanied by some twitching? If so, it also has to do with the warming up process. My RES will sometimes get really spastic.
