How would the varying shapes of the Pyrex, metal, and Styrofoam cups influence the time-temperature data? Which other variables might influence the data in this experiment?

Question 2

Which cookie sheet would you choose when baking cookies? Why?

Answer to Question 1

Food will take longer to cook if it is spread out over a greater area. The material used also affects the time-temperature data. Pyrex glass does not hold heat well, so the time-temperature data dropped rapidly. Metal traps some heat and kept the boiling water hot for a longer time. Styrofoam cups have the best time and temperature data for holding the boiling water. The aluminum loaf pan's water did not reach as high of a temperature as the aluminum square pan. Density, surface area, humidity, and thermometer calibrations could all have an effect on the experiment.

Answer to Question 2

The aluminum cookie sheet is the best sheet to use when baking cookies because it is a good conductor of heat and decreases the incidence of over-baking. If baked at the correct time and temperature, the cookies will burn less. They will be even-colored and have the correct flavor and texture. Shiny aluminum pans should be used when light browning and a soft crust are desired.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
