You could enter the name of the experiment into the subject line of the appt and you'll be able to see it in the day view.

As for dividing it into sections, I'm not sure if I really understand your intentions. Are you just trying to make them easily distinguishable?

If that's the case, perhaps you could try setting up conditional formatting rules for your day view. For e.g., 7 am to 9 am would be marked red etc.
