Something else you might want to try is getting a Tickler file up and running. There are free directions in David's freebies area and around the Web. It is cheap, fast, and very useful. It functions like a calendar, but it holds physical things instead of just notes written in a date square. For example, you could have a folder for each experiment with your checklist stapled to the inside of the front cover. Check off as you go, scratch out those that don't apply, eliminate the tedious recopying of repetitive tasks. The Tickler file becomes useful as you are thinking you need to do the next step on another specific day. Just drop the folder in the correct day folder, and it will automatically pop up on that day. Open the folder, and pick up where you left off on the checklist.
It also works great for birthday reminder, concert tickets, reminders to change the smoke detector batteries - just drop a note or a physical thing into the correct day or month folder, and it is out of the way and perfectly safe until the day it automatically pops up.
