TAKING CHEMISTRY THIS YEAR??? CHEMISTRY??? YEAHHHHH!!!!

I want to share with you about my gum lab! It’s my favorite lab experiment because I get to eat gum after the that!

Bubble Gum Scientific Method Lab

Ellie likes to chew bubblegum.  She has recently noticed that some types of gum lose flavor faster than others.  She wants you to figure out which gum lasts the longest, and which lasts for the shortest amount of time.  In order to do this, you must follow the steps of the scientific method.

Observation/Problem: Which type of gum last the longest???

Hypothesis: (in regards to shortest and longest) My hypothesis is depend on the size of the gum. the bigger gum, the longer the test. the biggest gum might be the Doublemint. 

Experiment:

      Materials: one piece of bubble gum per student, balance

Procedure Data
1. Take 1 piece of bubble gum of the same brand and flavor for each member of your lab group.  DO NOT unwrap the gum! Record the brand name and flavor in your data section. Brand Name: Dentyne ICE

Flavor: Cherry

2. While still wrapped, measure the total mass of all pieces of gum in your lab group using your balance.  Record the total mass in your data section. Total mass of all pieces of pre-chewed gum:

5g

3. Take the gum out of the wrapper and begin chewing.  Save the wrapper! Chew for 3 minutes- answer the first question in the analysis section while chewing… Observations while chewing:

  • crunchy
  • mintry
  • sweet
  • cold
  • spicy
  • strechy
  • gummy
4. After 5 minutes of chewing remove the gum from your mouth and place it back into its gum wrapper.  Find the mass of the gum/wrappers. Record the mass in your data section. Total mass of all pieces of chewed gum: 2g
5. Throw away your gum/wrappers and make sure that your lab station is clean.   checked!

Analysis: (answer these questions- show your work for math!)

Calculate the average mass of 1 piece of pre-chewed gum in wrapper (Take the total mass of pre-chewed gum in wrappers data#2 divided by the number of members in group)

5/3 = 1.66 g

Calculate the average mass of one piece of chewed gum in the wrapper (Take the total mass of chewed gum in wrappers data#4 divided by the number of members in group)

⅔ = 0.66 g

Calculate the average mass lost from chewing the gum (Analysis#1 minus Analysis#2)

1.66 – .66 = 1 g

Calculate the percent lost (Analysis #3 divided by analysis#1 and times by 100). Don’t forget to RECORD ON THE CLASS GRAPH

1/1.66 = 0.602409639

60.24%

Graph the percent lost from EACH type of gum.

Conclusion: (answer in full sentences)

Based on the graph,

Which gum last the least percentage of mass and therefore would last the longest? Which lost the most percentage of mass and therefore would last the shortest? Did this support or negate your hypothesis? What do you think was lost while chewing? What is one possible source of error (why you would have gotten inconsistent results) in this lab and how would it have affected your results? What would you do differently if you did this lab again to counteract this error?

 

The gum last the least percentage of mass and therefore would last the longest is the Trident. The most percentage of mass and therefore would last the shortest is Mentos. This doesn’t support my hypothesis because I think that the doublemint gum would last the longest, but it’s actually the Mentos gum. While chewing the gum I think it loses the mass and flavors. I got no error of this experiment, but if I do this lab again I would change the constance speed of chewing gum because if I chew the gum fast I will lost the flavor quickly. One thing I could also try is to place gum in the water instead of chewing it. When I place the gum into the water, all of the flavor is stay inside the water, when I chewed, the gum’s flavor is dissolved inside my mouth and it go through my guts.
