Title: 
Bubble Gum Chemistry 
Overview/Annotation: 
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.

Content Standard(s): 
SC(912) Chemistry  6. Solve stoichiometric problems involving relationships among the number of particles, moles, and masses of reactants and products in a chemical reaction.  MA2015(912) Algebraic Connections  5. Determine approximate rates of change of nonlinear relationships from graphical and numerical data. (Alabama)  MA2015(912) 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.

Local/National Standards: 
NS.912.1 SCIENCE AS INQUIRY As a result of activities in grades 912, all students should develop • Abilities necessary to do scientific inquiry • Understanding about scientific inquiry Standards from the National Academy Science 
Podcast(s): 

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. 
Approximate Duration of the Lesson: 
61 to 90 Minutes 
Materials and Equipment: 
Powerpoint lesson with practice problems, lab materials(see "Bite the Bubble" attachment), and graph paper 
Technology Resources Needed: 
LCD projector and an interactive board 
Background/Preparation: 
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. 
Procedures/Activities: 
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 45 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 xaxis and the percentage of sugar is placed on the yaxis. Different colored pencils may be used to represent different types of gum. Graphs may be done by lab group or individually.

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: 
Extension  Students can use the same procedure to test the percentage of artificial sweetener in sugarfree gum. 
Remediation: 
Practice problems(see attachment)
