# Science Fair Project: Which Chewing Gum Lasts the Longest?

## Try This Fun Gum Science Experiment!

Science fair projects don't have to be dull. This project tests which brand of gum has the longest lasting flavor. My kids and their friends really enjoyed doing this project. The adults and teenagers viewing the science fair project loved it too because it actually offers practical information you can use. When you go to buy gum, how can you get one that lasts longer? The results are startling.

We chose the question, "Which gum brand lasts the longest?" and used six different gum brands. It probably would have been better to choose gum with the same flavor, but my daughter thought that was boring, so we chose different flavors.

You could also use the question, "Which flavor of gum lasts the longest?" That experiment would use several flavors of the same brand of gum, maybe the gum brand you like the best.

Another gum experiment would be: "Which bubble gum makes the biggest bubbles?" In that experiment, you would have a variety of people blowing different types of gum and using a ruler to measure how big the bubbles are.

Or use the same brand of gum but different types, like stick vs. cubes or rolls. You would want to find a gum that had a variety of types. The question would be, "What shape of gum lasts the longest?"

Or you could try: "Which gum has more flavor, sugarless or sugared?"

## Science Fair Project on Gum, Step-by-Step

1. Choose a question.
2. Gather the materials.
4. Follow the procedures below to do the experiment or develop your own procedures. It might help to have a group discussion and agreement about how you are defining the word "flavorless."
5. Be sure to take pictures and to record your results carefully.
6. Ask your participants to give their thoughts and opinions along the way. What is important to them about gum? Which gum do they usually like? Do they chew gum after the flavor is out? How often do they chew?
8. Type up your results on the computer or handwrite them neatly. Attach them to a science board. You might want to put colored or patterned paper underneath them as a mat.
9. Before or after you do this project, check out the videos to learn about the history of gum and how it is made.

## Sample 4th Grade Science Project on Gum

How I thought of this project: All the kids in our family like to chew gum. Sometimes our parents give us some but other times we have to buy it ourselves. We all like different flavors but one of the things that makes gum taste good is if the flavor lasts a long time. So I thought about doing an experiment to test that. If I'm going to spend money, I want to know which gum will last the longest.

Question: Which brand of gum lasts the longest?
Hypothesis: I think that 5 gum will last the longest. Trident will be next. I think Stride will be 3rd, Juicy Fruit will be 4th, 5th will be Double Bubble, and 6th will be Extra.
The Materials:
I had six types of gum.
I had a piece of paper and a pencil to mark down how long the gum lasted.
I had a timer so I could keep track.
I gathered my sisters, brother, and friends to chew!

## Process for Science Experiment

1. First, I asked some people to help research my experiment.
2. We all sat together and I passed out the first type of gum. We all unwrapped the first gum, Double Bubble.
3. We said, “ready, set, go” and popped it in our mouths and started the timer.
4. We all chewed the gum and each person told me when their flavor ran out and I marked it down on my chart.
5. When everyone’s flavor ran out, we stopped the timer and got out another type of gum to do the experiment again.
6. We did this for all the gum.
7. Some people didn’t get a chance to try all the gums but I marked the ones they did try.

## Results of Chewing Gum Science Experiment

The Results: We recorded the results on a chart which showed the person who chewed and how long the flavor lasted.

What we noticed about the gums and the flavor:

1. My sister Sophie said she noticed that most of the flavors lasted with a strong flavor for one minute and then the flavor faded to just a little bit for the rest of the time.
2. Five has the most flavor. It is good and lasts a long time. The Stride gum lasts a long time but the flavor is not as good as 5 gum.
3. Juicy Fruit gum is harder to chew. The gum is stiffer. It seems to have last longer just because it was harder to chew.
4. Extra was pretty soft and was sweeter than the other gums.
5. All of the gums we chose were sugarless except for the Double Bubble.
6. Double Bubble is the best for blowing bubbles. You can blow bubbles with the others but not as well. 5 gum blows pretty good bubbles.
7. In 5 gum, I noticed that when I blew a bubble and put it back in my mouth the gum tasted sweeter.
8. Sophie noticed that when she wasn’t thinking about the flavor the whole time, the flavor seemed to last longer.

## Chewing Gum Science Experiment Favorites

1. Sophie likes 5 because it lasts a long time and Extra because it is sweeter.
2. Steffi likes Double Bubble because she likes to blow bubbles and Juicy Fruit because of the taste.
3. Mollie likes 5 and Trident because of their flavors and because they last a long time.
4. Brendan likes Juicy Fruit best but says it runs out quickly.
5. Maggie likes Extra because she likes the dessert flavors they have, but she also buys 5 a lot because she likes to chew gum that lasts a long time.

## Chewing Gum Science Fair Project Conclusion

1. The gum brands that lasted the longest were 5, Stride, and Extra. I was right that 5 gum would be the longest-lasting flavor and that Stride would be next. I was surprised that Extra lasted so long because I thought it would be the shortest since it is sweeter than most of the gums and has more unusual flavors.
2. I noticed that there is a big difference in how long gum lasts.
3. For smaller people, like my sister Steffi, the gum seems to have lasted longer than for bigger people. Maybe people with big mouths chew harder and faster.
4. When thinking about buying gum, people might want to try 5, Stride, or Extra if they like long-lasting flavor.

Step One: Keep a chart of how long each gum lasts. Get an average for each gum type. | Source
Step Two: Type it all up on your computer. Parents can help at this point, especially in setting up charts. We used Printshop to make the titles, but you can also use letter stickers. | Source
Step Three: Print out your project and cut off the extra paper. | Source
Step Four: Cut some colored paper for matting the parts of your project (we like colored scrapbook paper). | Source
Step Five: Mount the print-outs on the matting paper using glue sticks, glue dots, or double-sided tape. | Source
Step Six: Set up everything on your board and then glue it down. Sometimes, if we are having trouble getting things like the title to stick, we use a stapler like in this picture. | Source
Finished Science Board. Step Seven: Add on your pictures and boxes from your chewing gum. | Source

Hi Maddie--I was hit by a car and landed on my jaw when I was in my teens, so no bubblegum for me either. My kids sure had fun though!

I know I would have loved experiments like these when I was a kid. Unfortunately, my jaw was broken about 15 years ago, and it still gives me trouble. No bubble gum for me!

Great original photos, too!

Gina--here is a good way to figure this out:

(Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable)

VirginiaLynne 18 months ago from United States Author

Perhaps, although it might fit better into behavioral science. It is really a consumer science project but that isn't a category in the Intel ISEF projects, if that is what you are working under. I would not really categorize this project as one that would work for anything except elementary school or early Junior High unless you wanted to go into the chemical properties of the gum ingredients.

What category would you say this falls under? Chemistry?

Rymom28 18 months ago

This idea is so great! I'm bookmarking your hub for when my kids have a science fair project and just shared it with a friend. Thank you!

VirginiaLynne 19 months ago from United States Author

Laura--You are right--kids need to know that science can answer questions and that there is a process you can go through in order to test an idea. We were actually really surprised with the results of this project. My husband is a scientist, so he always wants the kids to do something fun for their projects so that they want to do it again next year!

Laura335 19 months ago from Pittsburgh, PA

This was a good idea. I hated the science fair when I was a kid. I could never think of an original project that worked. This experiment raises a question that we all think about. It might not be ground breaking science, but it does show kids how you can find the answer to a question if you are curious enough.

isabelle--Thanks so much for telling me about your project. I have 2 daughters in the 5th grade and they loved doing this project too!

VirginiaLynne 3 years ago from United States Author

I think you would do the same basic project outlined here but use the same brand of gun in lots of different flavors. Pick a gum that has a lot of varieties to make this work. Be sure you have several volunteers to work on it. Depending on the age of your daughter, you may want to try the experiment again with either a different brand of gun, or try the same flavor in different brands.

You could also find out what different sorts of flavorings are used or compare ingredient lists to see if you might identify which ingredient makes a difference!

Claudia 3 years ago

My daughter is intrested in doing this project. we need some help in reaserching "which flavor of gum last the longest" If you have any advice as to where we can research on this project please let me know as it is greatly appreciated.

Glad you like the idea Thundermama. I have a gum chewing project I just put up and I have a couple of other ones in the works, so check back! If you do the project, let me know how it turns out!

VirginiaLynne 4 years ago from United States Author

Hi Maddie--I couldn't participate either--I was hit by a car at 12 and also have jaw problems. The dentist hears my jaw "click" and asks me if I chew gum all the time though!

Thundermama 4 years ago from Canada

What a great project for elementary students. I am sure at least one of my daughter will be considering this as an option for their science project. Thanks for sharing!

Maddie Ruud 4 years ago from Oakland, CA

I know I would have loved experiments like these when I was a kid. Unfortunately, my jaw was broken about 15 years ago, and it still gives me trouble. No bubble gum for me!

Great original photos, too!
