I. Problem -How many licks does it take to get to the tootsie roll center of a tootsie pop? II. Materials -Tootsie Pop III. Data Analysis IV. Extension Questions 1. They seem to vary greatly with no real trend. 2. Average Guess=511.6 licks 3. They are, for the most part, relatively close. Ignoring the high and low outliers, they all lie between 307 and 507. 4. Average Actual=392.1 licks 5. There are many variables in this experience that we have no control over. Each person licks with a different technique and has a unique tootsie pop. One variable we could keep in check would be lick speed. Licking faster rids the mouth of saliva, possibly giving differing results. 6. -Have each student create an individual hypothesis as to how many licks it will take to reach the center of a tootsie pop. -Obtain tootsie pops of the same mass.
