=Gum-Base Test Lab= Bobby loves chewing gum and believes that if he chews a regular flavored gum instead of a flavored gum then he will get more gum base to chew. In order to test his idea, Bobby purchased a piece of regular and a piece of flavored bubble gum. He measured the mass (grams) of each piece before he chewed the gum and recorded the mass in a data table. He asked his friend Kevin to chew the flavored gum as he chewed the regular gum. Every 2 minutes they each remove the gum from their mouth and determine the mass (g). They continued this process until the mass no longer decreased(10 minutes).

You and your lab poster will test Bobby's hypothesis. Use the lab sheet provided by me! Pre-lab preperation: (Record on lab paper) 1. You will need to research what gum base is! 2. What is Bobby's hypothesis? 3. Identify the independent/manipulated variable. 4. Identify the dependent/responding variable. 5. Identify the controls.

Run lab and record data! ( Record on lab paper) Analyze data. Make conclusion (Restate hypothesis, discuss data, support or negate hypothesis)
