All product recommendations made by Ward's Science are suggestions for completion or extension of the activity or topics addressed, but are not required to complete the activity. 1. Students will follow instructions as written on attached activity. 2. Upon completion of the activity I provide them with the actual density of a Tootsie Roll (which I determine by finding the density of 3 Tootsie Rolls and averaging them D=1.34 g/cm 3 ) and instruct them to determine the percent error for their experimental result. Post-activity discussion: 1. Were the densities of the two different sizes of Tootsie Rolls similar? 2. Is this what you expected? Why? 3. Why do different sizes of Tootsie Rolls have similar densities? 4. What might account for your percent error?
