This document outlines lessons from Module 4 about percent error problems. It includes examples of students measuring a computer monitor with different measurements and Mary and Joe's experiment finding 1.7g of sugar in bubble gum when there should be 3g. It provides the homework problems and solutions. The closing questions ask about the differences between absolute and percent error, if they can be negative, and the benefit of calculating percent error.

In a bubble gum experiment Mary and Joe
found that there was 1.7 grams of sugar in a
piece of bubble gum. In actuality there
should be 3 grams of sugar. What was the
percent error in their experiment?
