Bubble Gum Chemistry


Students will learn to calculate the percentage composition of various compounds. As an extension they will then devise a similar method to calculate the percentage of sugar in various types of bubble gum.
This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

 Associated Standards and Objectives 
Content Standard(s):
MA2015 (2016)
Grade: 9-12
Algebraic Connections
5 ) Determine approximate rates of change of nonlinear relationships from graphical and numerical data. (Alabama)

a. Create graphical representations from tables, equations, or classroom-generated data to model consumer costs and to predict future outcomes. (Alabama)

MA2015 (2016)
Grade: 9-12
Algebraic Connections
7 ) Use analytical, numerical, and graphical methods to make financial and economic decisions, including those involving banking and investments, insurance, personal budgets, credit purchases, recreation, and deceptive and fraudulent pricing and advertising. (Alabama)

Examples: Determine the best choice of certificates of deposit, savings accounts, checking accounts, or loans. Compare the costs of fixed- or variable-rate mortgage loans. Compare costs associated with various credit cards. Determine the best cellular telephone plan for a budget.

a. Create, manually or with technological tools, graphs and tables related to personal finance and economics. (Alabama)

Example: Use spreadsheets to create an amortization table for a mortgage loan or a circle graph for a personal budget.

Local/National Standards:

NS.9-12.1 SCIENCE AS INQUIRY As a result of activities in grades 9-12, all students should develop • Abilities necessary to do scientific inquiry • Understanding about scientific inquiry Standards from the National Academy Science

Primary Learning Objective(s):

The student will be able to calculate the percentage composition of chemical compounds.

Additional Learning Objective(s):

Students will use the scientific method to solve a problem and use graphical analysis to compare data collected.

 Preparation Information 

Total Duration:

61 to 90 Minutes

Materials and Resources:

Powerpoint lesson with practice problems, lab materials(see "Bite the Bubble" attachment), and graph paper

Technology Resources Needed:

LCD projector and an interactive board


Students should be familiar with graphing techniques. Students must have a strong periodic table background and be able to use the periodic table to calculate molar mass.

1.) Powerpoint presentation see attachment"PercentageCompositionppt". This presentation includes percentage composition explanation and sample problems.Teacher will go through powerpoint giving students ample time to take notes and work/check example problems.

2.) Lab introduction and instructions (see attachment "BitetheBubbledoc.").Teacher will explain the lab step by step according to the procedure given.Students will work in groups of 4-5 students with varying ability levels.

3.) Group analysis of data - each group will put data on the group data sheet for comparison(see attachment"BubbleGumGroupDataTable.doc".

4.) Analysis of Data - Group data is displayed using a bar graph . The type of gum is graphed on the x-axis and the percentage of sugar is placed on the y-axis. Different colored pencils may be used to represent different types of gum. Graphs may be done by lab group or individually.

**Some files will display in a new window. Others will prompt you to download.

Assessment Strategies

Students will be evaluated according to the accuracy of the graph created (this will vary according to the materials used and graph scale chosen by each student). Graphs can be created by each lab group or by individual students.


Extension - Students can use the same procedure to test the percentage of artificial sweetener in sugar-free gum.
