Open your notebook to a blank page. Draw something small in the center of your page to represent yourself (a small x or circle will do). Sit quietly for a good 5 minutes.
Each time you hear a sound, draw a representation of that sound on your page in the direction you hear it (if you hear a sound behind you, draw it below yourself on your page).
Similar sounds should be drawn with the same symbol; if you hear two different winter wren songs, you should have two of the same symbol on your page when you finish. Different sounds should have different symbols.
At the end of the listening time, compare sounds and maps with other members of the group. Does where you sit make a difference? Were there loud sounds nearby that made it hard to hear the quieter ones? Were you wearing a hood? Did you use deer ears?
Try a new sound map in a different location or during a different time of day.
Set some strong expectations with this station. Remind students that this requires complete silence, and remind them of their P.E.R.C.S. if needed.
You could try doing a group sound map, with each student assigned to a different direction or section of the forest.
Be prepared to tell the students what you heard, too.
