    Lab: Apple's Oxidation

    In this lab students will learn about the chemical reaction, oxidation, using apple wedges. They will apply different substances to a number of apple wedges to determine if these applications have any impact on the oxidation process. Students will also use a control sample so that they compare their results with an apple wedge that has not had any substance added to it. Students will measure and record the time it takes to see the changes to the apple which indicate oxidation. 3-46
