2.  You all know that gum either contains sugar or some form of sweetener. This is why it tastes so good!  But, the sweetness does not last forever! Why??  Because the sweetener dissolves in your saliva, which means you consume it.  So, just how much of the gum is composed of sugar or sweetener? That is the question!  You will need to develop a procedure to go about investigating how much sugar is actually present in a piece of bubble gum. Yes, you’ll actually get to chew bubble gum for the purpose of science!  Brainstorm what information you’d need to calculate the percent of sugar in gum.

3.  You will need to focus on how much a piece of bubble gum's mass is made up of sugar. So think about ways to be able to calculate how much sugar was lost after chewing a piece of bubble gum.  To calculate the percentage of something: % = part x 100 whole  In our case: % = mass of sugar x 100 mass of unchewed gum  Write up a procedure of how you will go about gathering this data.

4.  Type up the following:  Materials needed.  Procedure written in the past tense!  Data collected.  Your results & calculations. In one sentence, say what the % was. Percent error: your result – true value x 100% true value  Each person needs to hand one in- it should not be exactly identical to your lab partner’s write up!
