I wasn't finding a symbolic/visual observation sheet for use my with MD students. So I made one.
It's overwhelming and many of the icons are subject to interpretation. My suggestion is to limit the choices... usually by folding, but also by scratching out choices.
This might also work with ESL students.
It has 5 categories of basic observation: see, feel, hear, smell, taste. The goal is to just get students recording what they observe in a very basic manner.
