The question that is presented in this activity is interesting because it gets students thinking about the amount of water that is on our planet and helps them see how much water is usable. There are several skills that are utilized in this activity but counting the number of squares can be a bit tedious even using the trick in the video. Although this activity is best suited for a classroom environment because of the number of maps that need to be counted; students working at home or by themselves can still work on the graphing part of this activity with the data that is available in the video, so they can still make a visual of the types of water available on the planet. The graph for this activity can be completed with graph paper and a pencil by drawing or coloring in the squares using the same key designated in the video.
