In room 7, we conducted an experiment around the age-old question, "How many licks does it take to get to the center of a Tootsie Roll Pop?" After we received our tootsie pops, we used our senses to make observations and then formed a hypothesis. A hypothesis is a scientific/educated guess based on what we know and observe. Next, we proceded to plan our experiment. Most of us took a lick of the tootsie pop and then recorded our data using tally marks. A lot of us had tired and sore tongues at the end of our test, but we never gave up! The next day we compared our data, and it was crazy! Our results were all over the place. Our minimum was 570 licks and our maximum was 5,010 licks. As you can see, the range was too large. There were too many variables, which are factors that affect experiments. We discovered we all had different definitions of what a lick was, and what the center of the tootsie pop was to begin with. Due to the many variables that were not controlled, the question still stands, unanswered. The world may never know how many licks it takes!
