Fill in the Results Table, summarizing differences between two grades of sheet gelatin. Use fresh gelatin for this exercise, since gelatin sheets pick up moisture during storage. Use the following steps as a guide in completing the table:

Use your textbook to find the average Bloom rating for each grade of gelatin. Record answers in column 1.
Read the net weight per box for each gelatin directly off the box and fill in the column labeled Weight per Box.
Weigh 10 sheets of each grade of sheet gelatin (to one number after the decimal point) and record weights of each sheet in the third column in Results Table 1.
Calculate the average weight per gelatin sheet by dividing the total weight of 10 sheets by ten. Record calculated weight per sheet in the fourth column.
Estimate the number of sheets per box by dividing the weight per box by the average weight per sheet. Record in the fifth column.
Estimate the number of sheets per ounce by dividing 28.35 (the number of grams per ounce) by the average weight for one sheet (in grams). Record results in sixth column.
Record in the Comments column the sensory characteristics of the sheets: Touch the sheets and compare how the different grades compare in feel (which feels thicker, heavier). Next, if available from the following experiment, smell warmed gelatin solutions. Record strength of meaty aroma, comparing each to the aroma of the powdered gelatin solution.
