 So, this is my lab notebook and it can be a really helpful tool for you to remember past experiments that you've done and to remember past techniques and protocols and it also serves as a document, an official document of what you've achieved during your time in a lab. So, the most important, what I would argue is the most important thing of a lab notebook is your table of contents. It takes a little bit of extra time to do, but it's really helpful when you're trying to look back to a past experiment or technique and you need to find it quickly. And it also helps you keep very organized. The next important thing is, so here's a page of my lab notebook and you can see it's numbered and it has sections up here for both the project and the title of whatever I'm documenting here on this page. So the project is really important because that will allow you to differentiate between different projects that you might be working on, so sometimes you might be using the same assay for a different project and it helps sort of differentiate. It's also really important to have a detailed title that will help you remember sort of what you did at a glance. So I like to talk a little bit about what technique I'm doing in that section as well as sort of basically what sort of cell type I'm looking for with and so forth. It's also really important just to write a quick sentence about why you're doing this experiment, what your objective is that helps sort of keep your eye on the prize and helps you sort of remember why you're doing it. It's also really helpful to actually have printouts from equipment that you've used and your actual data that can help legitimize what you're doing and can also help you also help when you're looking back and trying to double check things and so forth. It's also really helpful to have images of what you're doing or what you've done, especially if you're doing cell work. It can be really helpful if your cells change morphology or structure over time. It can be really helpful to be able to look back on that. For instance, on one day these cells were really monolayer, they were growing in a monolayer and they had a very spindle-shaped morphology and seven days later they formed this giant structure, this blob shape. So that was really helpful for me to look back and say, oh yeah, these cells are, they definitely changed over time. Lastly, it's really, really important to outline your protocol. So I like to write down every little step, even something that doesn't seem relevant at the time because later on you may actually want to look back and say, which media did I use there and how long did I incubate that for? And if you take really good notes you'll be able to actually look back and get that information. It's also really important to note down which materials you use because, oftentimes there are hundreds of different medias you can take and choose from and hundreds of different antibodies and so forth. So it's really helpful to have the name of whatever you're using as well as tablog numbers and lot numbers that can save you a lot of time later on as well. So another really important part, another reason why it's really important to take really good detailed notes in addition to helping you out as a researcher, enabling you to look back on what you've done and remember everything. It's also, your supervisor may also want to take a look at your notebook. And it serves as almost a diary or a log for them to actually be able to look back and understand what you're doing and why. So it can serve as an official record of what you've done.
