1. GUM FLAVOR Which brand of gum has longer lasting flavor? November/December 2004

2. Hypothesis My hypothesis: I hypothesize that Juicy Fruit’s flavor will last longer than the other brands because it says “now with longer taste” on the package. How will I test this? I will test how long the flavor of each brand lasts by chewing each brand of gum until the flavor is gone. How will I make this a fair experiment? I will taste test each brand four times, time how long the flavor lasts, and then record the results.

3. Materials 4 3.5g pieces of Juicy Fruit gum 4 8g pieces of Bubble Yum gum 4 8g pieces of Bubblicious gum 1 pencil 1 notebook 1 clock 1 calculator Notes and instructions Triple beam balance

4. Procedure 1.Take Bubble Yum gum piece and remove the wrapper. 2.Put gum in mouth and start chewing; begin timer and record start time. 3.Chew until taste is gone and record end time. 4.Now take the end time and subtract the start time to get the number of minutes the flavor lasted. 5.Repeat steps 1-4 with other brands of gum. 6.Repeat this experiment 4 times with each brand.

5. Trial One GUM BRANDTIME (in minutes) B UBBLE Y UM 9:16 am – 9:32 am Flavor lasted 16 minutes B UBBLICIOUS 9:33 am –9:44 am Flavor lasted 11 minutes J UICY F RUIT 9:44 am – 10:48 am Flavor lasted 64 minutes

6. Trial Two GUM BRANDTIME (in minutes) B UBBLE Y UM 11:47 am – 12:05pm Flavor lasted 18 minutes B UBBLICIOUS 12:05 pm – 12:27 pm Flavor lasted 22 minutes J UICY F RUIT 12:29 pm – 1:26 pm Flavor lasted 57 minutes

7. Trial Three GUM BRANDTIME (in minutes) B UBBLE Y UM 1:27 pm – 1:52pm Flavor lasted 25 minutes B UBBLICIOUS 1:53 pm – 2:20 pm Flavor lasted 27 minutes J UICY F RUIT 2:21 pm – 3:54 pm Flavor lasted 93 minutes

8. Trial Four GUM BRANDTIME (in minutes) B UBBLE Y UM 3:54 pm – 4:11 pm Flavor lasted 17 minutes B UBBLICIOUS 4:11 pm – 4:30 pm Flavor lasted 19 minutes J UICY F RUIT 4:30 pm – 5:36 pm Flavor lasted 66 minutes

9. The Average GUM BRANDTHE AVERAGE TIME OF THE 4 TRIALS (in minutes) B UBBLE Y UM (16 + 18 + 25 +17)  4 = 19 minutes B UBBLICIOUS (11 + 22 + 27 + 19)  4 = 19.75 minutes J UICY F RUIT (64 + 57 + 93 + 66)  4 = 70 minutes

10. Gum Flavor Time Trials

11. Conclusion ( Part One ) So was my hypothesis right? My hypothesis was proven right. The flavor of Juicy Fruit gum lasted the longest in all four of my tests. What did I learn? I learned that Juicy Fruit brand’s flavor lasts longer than Bubble Yum and Bubblicious while doing this experiment.

12. Conclusion ( Part Two ) Any recommendations? I recommend Juicy Fruit brand of gum because in all four of my experiments, Juicy Fruit gum lasted the longest for flavor out of Bubble Yum and Bubblicious. Would You Change Anything? Next time I would change the brands of gum I choose and get ones with the same amount of grams in each piece to see if it would change my answer.

13. Conclusion ( Part Three ) Any errors? My source of error was that I couldn’t chew each piece at the same speed. This would cause the flavor to disappear faster or slower depending on the speed the gum was chewed. Any Problems? When doing this experiment, I had a problem with chewing each piece at the same speed and chewing gum all day, because it made my jaw sore.

14. Conclusion ( Part Four ) Was this a fair experiment? This was a fair experiment. The chewing speed probably did not affect the final conclusion because the amount of time the flavor lasted in each test was so far apart. What is your new question? A new question I now have is, will Juicy Fruit’s flavor last longer than other brands of gum (other than Bubble Yum and Bubblicious)?
