Description:

This exercise is designed to give the students a hands-on experience in which they can relate different orientations of an indicatrix to the different birefringence observed for each orientation. Each student is given a piece of fruit that has the shape of a uniaxial indicatrix - either a kiwi (uniaxial positive) or a tangerine (uniaxial negative). The student follows a set of instructions to insert toothpicks to represent the different indicatrix axes and to draw on the fruit using a permanent marker the circular and principal sections. Then the student is asked a series of questions asking them to determine the birefringence of the mineral for different orientations of the fruit.
