If you want to make your own natural history observations, The Naturalist’s Notebook (Storey Publishing, 2017) by Wheelwright and Bernd Heinrich, emeritus professor of biology at the University of Vermont, provides guidance and a systematic format, with 100% of royalties going to conservation and environmental education.
