Enjoy it! It's probably the only lesson you will have for a while where you will have a chance to look at the scenery too, so don't worry too much about nailing the turns and stuff, just become aware of how beautiful this country really is from above! (Yup, even Coventry looks OK up there.)
If it's one of your first times in a small cockpit too, you will of course be nervous and it is an experience like no other! A point worth noting if it is a bit wobbly up there in your opinion is that the instructor is never going to do anything to put either of you in danger, so relax...
Try to develop some casual conversation with the instructor, as it's all about having fun at the end of the day, and none of the training I've done so far has been too taxing.
Let us know how you get on!
