Beach Bucket Sorting

We then discussed how the earth might be more accurately called planet ocean as over 70% of the earth's surface is water. We played a game with a globe beach ball. We threw it to each other and each time someone caught it we looked to see whether the hands were mostly touching land or water. We wrote it down each time. After we were finished about 10 throws (or 20 hands worth of data) we calculated the percentages. They were amazed to see that it came out to nearly 70% of the time touching water!
