Take your kids out of the classroom, set up the 7 station activities, then facilitate while they do all the work! In this activity, TLW explain the concepts of threshold and adaptation, describe the visual sensory system, describe the auditory system, describe other sensory systems, such as olfaction, gustation, and somasthesis, and describe the importance of binocular clues. The students LOVE this activity! I have used it as a formal observation and got excellent reviews from my administrator
