# On Your Mark, Get Set, BOB!!! (Ultimate BFA Duel)

**On October 31 2012, two grade eight classes from F.E. Madill Elementary went head to head in an Ultimate Bobbing For Apples Duel. These two classes were, 8A Mr. Westra’s class, and 8B Mrs. Durnin’s class. We decided to have this amazing event in the gym on Halloween because bobbing for apples is a Halloween tradition. Also we were learning about collecting data in math, and wanted something fun to do our projects on. So after all of the pairs (one from 8A and one from 8B) competed in the Ultimate BFA Duel, everyone in the two classes created graphs and charts to display the data. We then made connections on our graphs. So the only thing left to decide is, which class won? **

**#9)a) Based on the data in the charts and my graphs, I can make a conclusion that 8B took less time to catch our first apple then 8A. For example, if you look at the “Times To Get First Apples” graph, you can clearly tell that 8B caught most of our apples in 0-20 seconds, while 8A had some of their apples caught in 60-1:20 or 1:20-1:40 seconds. I can also make the conclusion that 8B caught much more apples than 8A. For example if you look at the “Total Number Of Apples Caught In A Minute” graph, you can see that 8B caught more than double the amount of apples than 8A. 8B caught 28 apples, and 8A caught 12 apples. 12×2=24, 28>24.**

**#9)b) Some inferences I can make are that I noticed that 8B had the strategy of pushing the apples over to the edge of the bucket, so then it is easier to grab ahold of them. This must be how we snatched up so many apples in such little time. Also 8B had a way of putting their head upside down in the water, and sliding the apple up the wall of the bucket, until we had it firmly in our mouth. **

**#9)c) The winner of the Ultimate BFA Duel is…8B!!! Of course it was us! To figure out for sure who the winner was, I calculated the mean for “Number Of Apples Caught In A Minute” and “Time To Get First Apple.” I came to the conclusion that the mean for “Number Of Apple Caught In A Minute” was, 4 for 8B, and 1.17 for 8A. Also for “Time To Get First Apple” we came plowing through with a mean of 17.71 for 8B and 33.86 for 8A. Just like Mrs. Durnin predicted, we pummeled 8A! **

Great post Nicole! I like how you said who won, then explained how you came to that conclusion. Next time don’t include the question (#9), it will look great that way! I like how you said that Mrs. D was right, that we’d pummel 8A. Keep up the good work! 🙂
