Which Cools Faster?

Project #1500 on iSENSEProject.org

Who cools off faster after a game:  
Rob Gronkowski (large body) or Danny Amendola (small body)?

Does body size affect cooling rate?  After a rough Sunday night game, whose body cools faster... Rob Gronkowski at 6'6" and 265 pounds or Danny Amendola at 5'11" and
190 pounds?  Of course there are many factors that can affect the rates at which these Patriots players cool off, but what happens if we take away most of the variables and leave only one - size?

In this investigation, students will use a model to investigate this question by comparing temperature changes inside two different sized bottles of water.  Students will fill two plastic bottles of different sizes (one 2 liter bottle and one 355 milliliter bottle) with hot tap water. Students will insert temperature probes into each bottle and secure with masking tape. Temperature probe tip should be submerged in 1 inch of water in each bottle.  After the temperature stops rising and evens out, students will begin data collection.  After collecting data for 20 minutes or more, they will save the data set, load it into iSense, and view visualizations of the data.

Questions:
1.  Looking at the default line graph visualization, was there any difference in the cooling            rates of the bottles? Which one cooled off faster - the large bottle or small bottle?

2.  Be sure both data sets are selected and look at the histogram.  What does this imply?

Note:  Data was collected for 2 collections per minute for approximately 90 minutes.  One probe was placed in a 2 liter Canada Dry diet ginger ale bottle and the other probe was placed in a 355 mL Canada Dry diet ginger ale bottle.  Both bottles were the same (except for size) and had proportional amounts of water (same temperature), as compared; to their size.
