Objective

To determine how much sugar is in each type of drink.

  • Fruit Juice
  • Fresh Squeezed Fruit Juice
  • Organic Fruit Juice
  • Soda 

Introduction

It’s commonly known that soda has a large quantity of sugar. But how much sugar is there in fruit juice? Does it matter that it’s “fresh squeezed” or that it’s “organic”? What is the purpose of these labels, and what do they tell us about the amount of added sugar? 

Research Questions
  • Which has the most sugar: Fruit Juice, Fresh Squeezed Fruit Juice, Organic Fruit Juice, or Soda?
  • Are the nutritional content labels correct, or are they only counting added sugar? 
Terms, Concepts and Questions to Start Background Research
  • What are the labeling laws that concern fruit juice?
  • How much sugar do normal Americans drink every day?
  • What are the differences between the amount of sugar in different kinds of fruit juice? 

Experimental Procedure

  1. Weigh the pot you are using on a scale. Note how much it weighs.
  2. Take the Fruit Juice, and pour a predetermined amount into the pot.
  3. Boil until all the water evaporates. All that will be left is the sugar.
  4. Weight the pot now (once it cools), and subtract the initial weight of the pot. This is how much sugar is in the drink.
  5. Repeat with Fresh Squeezed Fruit Juice, Organic Fruit Juice, and Soda.
