Arts & Sciences Documentation shouldn't be a big scary thing, it's simply a record of your research efforts: the sources you used, the assumptions you made, the experiments you made, and the results you obtained. It's a method of helping someone else learn what you did and follow along with you.
The 5 W's are key to documentation:
- What is it?
- When is it from?
- Where is it from?
- Who would have used/made/done it?
- Why did it exist pre-1600 and why did you make it?
- How did you do it?
Although documentation is always good to have it is also required if you're interested in entering an Arts & Sciences competition.
