We have one final activity left in this chapter, a "Speaking of Space" activity that has been designed to provide a slightly different experience for you from those of the previous chapters. Directions are provided in the next section. After this activity, we have only one more chapter in the book, a chapter that examines how space flight affects the sensory and balance system of the body. Let's begin our "Speaking of Space" activity and then let's move on to the last chapter of the book!
