These two activities (4th on the page) demonstrate the importance of two eyes in judging depth. In the first activity, two learners compare the accuracy of dropping objects into a cup using only one eye or both eyes. In the second activity (a game), learners test the accuracy of dropping a marker onto a target using only one eye or both eyes. These activities can be used separately or in conjunction to illustrate how depth perception affects our ability to complete tasks.
