Jennifer Wagner is back with Oreo 2004. Our class was involved with this delicious way to learn more about the world of mathematical thinking.
The hypothesis is that the creme filling in 25 DOUBLE STUF OREOS will NOT BE DOUBLE that of
THE WEIGHT of the filling in 25 REGULAR STUF OREOS.
This hypothesis will be proved or disproved after all results
have been received from participants and averaged as a whole!
STEP 1 - THE HYPOTHESIS
Our first job was to discuss what a hypothesis is. I put the word on the board and asked if anyone thought they knew what it meant. Johnathan thought it might be some kind of animal (a great guess!). We discussed how it is an idea that a mathematician or scientist has about something, and how a hypothesis is tested to see if it's right or wrong.
STEP 2 - FAMILY HOMEWORK
Next, the children had Family Homework which included a family discussion about the project's hypothesis and votes from parents and students about their own ideas. We discussed these back in class. Here is what parents and students thought.
(Based on homework returned the day of the project)
STEP 3 - PUTTING THE HYPOTHESIS TO THE TEST
Before we began our scraping, we decided to give ourselves a clue as to the answer. We weighed 10 regular oreos and then 10 double stuf oreos. We thought that the double stuf would weigh twice as much...
BUT they didn't! The regular weighed 5 ounces and the double stuf weighed 7 ounces. We began to think that maybe the project's hypothesis was right, and many of us were wrong! On to the scraping...
People with double stuf oreos
had a much easier time scraping!
STEP 4 - THE RESULTS
Tables 1 and 2 had regular oreos, and here are the weights of their filling:
1 oz. + 2 oz. =
Tables 3 and 4 had double stuf oreos, and here are the weights of their filling:
2 oz. + 4 oz. =
What did we learn? In our work, we learned that the hypothesis of the project was wrong - the weight of the filling in double stuf oreos IS double the weight of the filling in regular oreos - many of our predictions had been correct!
What's equally interesting is that several other classes across the country got the EXACT same results as we did! Many classes, even with different data, did find that there was double the filling, but others did not. Click HERE to see project results!
