What Percentage Do I Eat?

DIRECTIONS: What part of the nut do you actually eat? How much of the nut does that represent? Your challenge is to determine the percentage of the nut by mass that is edible. Three nuts are named in the chart; add others, continuing the chart on the other side.

PROCEDURE:

  1. Obtain the materials from your teacher.
  2. Weigh each nut. Remove the shell and weigh the part that you eat and weigh the shell. Calculate the percentage of the nut that is edible using this formula: Mass of the nut meat/Total mass of the nut X 100% = % edible.
  3. Record your data and calculations in the table below.
