CP ALGEBRA 2



Honors Precalculus - NEWTON’S LAW OF COOLING EXPERIMENTDirections: For full credit, all of the following must be completed. You can get a total of 10 points if all the following is completed. Include this paper with your work._____ 1. A pie must be BAKED, not necessarily from scratch, but it must be some type of pie, NOT a cake, cupcake, cookie or pi! You then must bring it in to share with the class._____ 2. A complete set of temperature readings at different times (at least 10 readings) must be included in table form._____ 3. A scatter plot of temperature readings plotted versus time._____ 4. A hand-determined model to Newton’s Law using two different temperature readings from your results. (State the 2 ordered pairs). If you prefer to use regression with your calculator (and all your temperature readings), you can, but you must show work in order to rewrite in a usable form. There are examples of both of these methods in your notes from section 3.5._____ 5. The graph of your model superimposed over the scatterplot in #3. This should be continuous._____ 6. Find another model, other than Newton’s Law of Cooling that could accurately fit your data set. State this function, with numbers, and describe why you picked this model. _____ 7. A brief, but thorough, explanation of your experiment. HELPFUL HINTS: 1. Make sure your surrounding temperature can remain constant.2. Do not go by the temperature reading the instant you remove the pie from the oven. Wait and watch until it reaches a maximum. It will continue to bake itself when removed from the oven. Start with your maximum temperature as . 3. If you cannot bake, get help!4. Please DO NOT, under any circumstances, use a glass-bulb thermometer! A regular meat thermometer with markings for at least every two degrees should suffice.5. Use time intervals between 10 and 15 minutes. ................
