The secretary should turn this sheet in when all team members have the information. One way to rate popcorn is to determine which brand ends up with the fewest unpopped kernels. FIND: The best and worst of three brands of popcorn. a. Count out 100 kernels (or some such reasonable number) of one of the brands of popcorn.  Pop the 100 kernels. *** Brand of popcorn popped by your group:_________________ b. When the popping is complete, count the popped kernels. Count the unpopped kernels. Do they add to 100? *** Number of popped kernels: __________________ *** Number of unpopped kernels: __________________ *** Total of popped and unpopped kernels: _________________ c. What fraction of the popcorn is popped? What fraction of the popcorn is unpopped? *** Fraction of popped kernels: __________________ *** Fraction of unpopped kernels: __________________ d. What percent of the popcorn is popped? What percent of the popcorn is unpopped? *** Percent of popped kernels: __________________ *** Percent of unpopped kernels: __________________ e. Obtain the information for steps a. through d. collected by the other groups for the two other brands of popcorn. f. Which brand of popcorn had the smallest percent of unpopped kernels? Which brand had the largest percent of unpopped kernels? *** Make a bar graph which shows the percent of unpopped kernels for each brand of popcorn.
