I don’t ask students to do this a lot but sometimes they just need to have the experience of doing a detailed sketch. We actually have vintage microviewers and students look at sets of photomicrographs when we study the Moon, telescopes, and the Sun in astronomy. Attention to detail and diagramming what one sees is a skill that won’t go away. The example above was done today by one of my students and really is exceptional. I also get to tell students about my favorite word; syzygy. Try writing it in cursive and all lower case!
