I thought it might inspire you to see some more science notebooks.
The top two photos are from my extremely talented husband's book. He would have been about 17 or 18, I guess, when he drew those. Sorry the photos are a bit dark, but you can still see the incredible neatness. This book is quite beautiful, I think.
The rest of the photos are from my notebook. I would have been 14 or 15, I guess. They're not nearly as good as my beloved's, but I'm guessing they're far more approachable for those of you toying with the idea of starting a notebook of your own.
I'm so glad we didn't ever throw these away.
Sorry to those of you that have already seen these on FaceBook.
