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 board 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.
You can be creative because there are a lot of different questions you could choose when doing a project on gum. Here are six:
- "Which gum brand lasts the longest?" This was the question we chose and my daughter used six different gum brands. You could certainly use more brands to make a more complicated project. 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.
- "Which flavor of gum lasts the longest?" This experiment would use several flavors of the same brand of gum, maybe the gum brand you like the best.
- "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.
- "What shape of gum lasts the longest?" 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.
- "Which gum has more flavor, sugarless or sugared?" You could use different types of the same brand and maybe also try different flavors.
- Which brand of gum do people like best? In this experiment, you would give people several different brands of gum to try with no labels. Try to choose gum that can't be easily identified just by looking at it. You can have them rate them on taste, chewiness, bubbles, long-lasting flavor or any other characteristic. Have them put them in order of favorite to least favorite. It might be interesting to also quiz them before or after the experiment to find out which brand they think is their favorite.
Step by Step Photo Instructions
- Choose a question.
- Gather the materials.
- Decide on your own hypothesis—your guess of the answer.
- 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."
- Be sure to take pictures and to record your results carefully.
- 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?
- Look at your results and think about your question. Write down your results and conclusions.
- 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.
- Before or after you do this project, check out the videos to learn about the history of gum and how it is made.
4th Grade Science Fair Project
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.
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!
Sample Table for Gum Experiment
|Stride||Juicy Fruit||5||Hubba Bubba||Trident||Extra|
- First, I asked some people to help research my experiment.
- We all sat together and I passed out the first type of gum. We all unwrapped the first gum, Double Bubble.
- We said, “ready, set, go” and popped it in our mouths and started the timer.
- We all chewed the gum and each person told me when their flavor ran out and I marked it down on my chart.
- When everyone’s flavor ran out, we stopped the timer and got out another type of gum to do the experiment again.
- We did this for all the gum.
- Some people didn’t get a chance to try all the different brands but I marked the ones they did try.
We recorded the results on a chart which showed the person who chewed and how long the flavor lasted. What we noticed:
- Person 2 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.
- 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.
- Juicy Fruit gum is harder to chew. The gum is stiffer. It seems to have last longer just because it was harder to chew.
- Extra was pretty soft and was sweeter than the other gums.
- All of the gum brands we chose were sugarless except for the Double Bubble.
- 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.
- In 5 gum, I noticed that when I blew a bubble and put it back in my mouth the gum tasted sweeter.
- Person 3 noticed that when she wasn’t thinking about the flavor the whole time, the flavor seemed to last longer.
Which Gum is Your Favorite?
- Person 1 likes 5 because it lasts a long time and Extra because it is sweeter.
- Person 2 likes Double Bubble because she likes to blow bubbles and Juicy Fruit because of the taste.
- Person 3 likes 5 and Trident because of their flavors and because they last a long time.
- Person 4 likes Juicy Fruit best but says it runs out quickly.
- Person 5 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.
- 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.
- I noticed that there is a big difference in how long gum lasts.
- 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.
- When thinking about buying gum, people might want to try 5, Stride, or Extra if they like long-lasting flavor.
How to Put Science Fair Board Together
Questions & Answers
Question: Could you do the same project with only one person?
Answer: That might be a way to test the different types of gum with only one variable. However, it helps to have more replicates and larger sample sizes to make sure the data is accurate.
Question: Where can you find keywords to research for "what chewing gum lasts the longest"? Would you happen to know 3 key words also?
Answer: What are appropriate for "key words" would depend on why you need these. If you are using key words to look up research on this topic, I would suggest "chewing gum," "gum marketing," "gum consumer research."
Question: Is the chewing gum science experiment healthy?
Answer: If you choose sugar-free chewing gum then I think you can consider this a healthy science experiment. Sugar-free gum has been shown to help people keep their teeth cleaner. According to the American Dental Association, when people chew gum, they release saliva which can help wash away bacteria and food particles which harm teeth. Look for the ADA symbol on gum to see if it is certified as healthy by the American Dental Association. It might be an interesting project to compare ADA gums and ones that are not certified. A non-certified product may also be healthy, but it has not gone to the trouble of providing proof to the ADA.

Hi Amy--put the website link into EasyBib or see my article on MLA citation.
Amy Harrison on October 18, 2019:
Thanks for your insight how do I site your work as my resource
connor on August 27, 2019:
thanks a lot!
M Ray on December 28, 2018:
THANK YOU so MUCH for posting this, my grandson is working on a similar project and I am having him follow some of your guide lines.
Jasmine brown on December 19, 2018:
I used this you, help me so much, thank you!!!!
Stephanie on December 11, 2018:
This page helped me a lot with my project. Thank you!!
Virginia Kearney (author) from United States on November 27, 2018:
Hi Chris--there are background research essays you can find but you will need to do that research yourself. You can look under "chewing gum research."
Chris on November 27, 2018:
Do this project have a paper about background research?
Virginia Kearney (author) from United States on November 20, 2018:
Hi Maggie--we did this project in a day and my daughter took another day to write up her data and make her board.
Maggie Dye on November 19, 2018:
Would this be a quick project?
Charles dddDickens on September 20, 2018:
I WAS NOT EXPECTING THAT OUTCOME!!! PERSONALLY I PREFER EXTRA BUT IT LOOKS LIKE I'LL BE SWAPPING OVER TO 5! THANKS VIRGINIA!
Virginia Kearney (author) from United States on April 16, 2018:
Hi Jade, I think 5th graders could do this project but you might want to include more people doing the experiment.
Jade on April 15, 2018:
Is this a good project for 5th graders?
Virginia Kearney (author) from United States on February 05, 2018:
Hi Wasee, this project would be a good one for a competition. I hope you have a good time and come back to comment on how it went!
Virginia Kearney (author) from United States on February 05, 2018:
Hi Lucien, I'm very happy to have you do this same project. You can change some of the variables and make it your own. That means you could use different kinds of gum, or different flavors of the same gum. You could have more people try your experiment, or compare older people to younger people. Use your imagination!
Wasee on February 04, 2018:
DO YOU KNOW THE WAY?!? Im just in sixth grade.
Can this project help me in the science fair?
Virginia Kearney (author) from United States on February 03, 2018:
Hi Lucien, I have a project that is just for kindergarteners. It is: https://wehavekids.com/education/Elementary-Scienc...
You can also look at my description of how to put your board together for help.
lucien holland on February 03, 2018:
is it all right if i do the project u guys did Virginia?
Elicia on January 18, 2018:
Isaiah on January 18, 2018:
i will put that into mind and i will research that thanks for responding.
Virginia Kearney (author) from United States on January 16, 2018:
Hi Isaiah--that would make a good research question. You could find out whether gum that had different textures lasted longer. Or you could find out whether gum that was in a stick lasted longer than a cube.
Isaiah on January 16, 2018:
does the texture of the gum effect how long the gum lasts? Because you said that juicy fruit lasts longest because its hard to chew? would it change if it was soft and easy to chew?
Maya on November 26, 2017:
I am literally doing it RIGHT NOW
mason hepburn on November 15, 2017:
I am doing this as an experiment right now and my parents are on my tale about it
Kyalie Perry on November 15, 2017:
This is a good science project.
Oliver on September 29, 2017:
I'm doing the exact same thing right now for scienc I am just about to finish it.
Virginia Kearney (author) from United States on May 15, 2017:
Hi, Charlie! That would be an excellent question to research. You might even ask the people in your experiment what gum they think is most popular among their friends. I'm sure that you can find the answer to which gum is purchased the most if you use a search engine.
Charlie on May 15, 2017:
What gum is used the most?
Virginia Kearney (author) from United States on May 03, 2017:
The different types of gum and the different people chewing.
Lucy surf on May 02, 2017:
What were the variables
hi on May 02, 2017:
i never thought that 5 would last long this is alot of help

Hi Jazzy--My daughters like Hubba Bubba but I don't think we did that one for the project. After you do it, come back and tell me.
Jazzy on April 14, 2017:
Hi my name is Jazzy and im in the 5th grade! And im doing think exact project and its due in a couple days..... and i wanted to know how long did hubba bubba take? If you did it? tyvm( Thank you Very Much)

Hi Kristen--I always include my sources on photos. If the photos are not my own, they are usually from Pixaby which has photos which are uploaded by individuals to their website and are offered as Public Domain pictures for free use online in private or commercial use. If you click on "source" underneath the picture, you can see that it comes from "Live, Laugh, Love" from Pixaby. If she objects to having her picture offered for use, you should contact the person who uploaded the photo.
Kristen Clarke on March 11, 2017:
Where did you get the picture of the little girl with freckles blowing the bubble? That is my niece and I curious how you got the photo
Virginia Kearney (author) from United States on March 09, 2017:
Hi Gracie--I hope you enjoy doing this experiment. I think you can either put the names of the people or just give each person a number on the chart. The problem is the question in the title.
Gracie on March 09, 2017:
So in science class I have to do a science project and it's due on
(Apr,19) and it's based on gum and I was wondering how to do and so I'm looking at your details and there very awesome matter of fact have some question um well here is a list of them
1.)on your chart do you need to put you name or just your family member.
2.)what is your problem for your experiment. and this is just a fact which kind of book has a title of gum. so I think that's it maybe but I really love your (Experiment)
FYI,I AM (11 yrs) old and I AM IN ( 5th grade) and this year is middle school. yeahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!
GG on January 18, 2017:
I also found that the fruity was more addictive even if they brand is sugar free.
Virginia Kearney (author) from United States on January 15, 2017:
Raymond: The project takes a couple of hours for the experiment and then, of course, more time to type up everything and make the board. Each of the gum samples cost between one and two dollars for a pack.
Raymond Martinez on January 15, 2017:
how long did it take to do the project and how much was the items???
Virginia Kearney (author) from United States on January 14, 2017:
Hi Vanessa--I think whether you win depends on your grade level, the competition you are going against and how carefully you do your project. This project is really mostly for lower elementary grade students.
Vanessa on January 14, 2017:
Will this win a Science fair project??
Virginia Kearney (author) from United States on January 12, 2017:
GG-That is interesting. I wonder if it is because mint is a stronger flavor?
GG on January 12, 2017:
I am in 7th grade and I did the same thing and I noticed that a minty flavor will last the longer than a fruity one
#swaggy boss on January 08, 2017:
I was anonymous I swear and I love this site and I am in 6th grade so I did the same experiment I was just on the internet looking for a topic and here I found you . you inspired me for this project I hope I win
anonymous on December 23, 2016:
this helped so much thanks
Virginia Kearney (author) from United States on December 05, 2016:
Hi Leah--in order to figure out different requirements for your particular project, you need to think about what the terms mean:
Dependent variable: one aspect of your experiment which depends on something else.
Independent variable: one aspect that won't be changed no matter what else happens in the experiment.
Leah on December 04, 2016:
What's the independent variable for this project???
lizabeth on November 15, 2016:
hubba bubba or juicy fruit
Virginia Kearney (author) from United States on November 06, 2016:
It is probably a good idea to show this idea to your instructor and ask them to make sure you understand what they mean by controlled variable. Probably the fact that you use the same people and the same gum to do the experiment and that they do the same activity. What is the experimental variable is the fact that people chew differently and their taste buds react differently to the gum.
Stewert Robb on November 06, 2016:
What is the controlled variable in this experiemnet
Iliana Freeman on October 31, 2016:
I really like your experiment. gum is the bomb!!!!!!!!!!!!!!!!!!!!
Panda Panda PANDA on October 31, 2016:
I LOVE TO DO THESE TYPES OF EXPERIMENTS
Barbra Robins on October 11, 2016:
Virginia Lynne-- thank you
Virginia Kearney (author) from United States on October 10, 2016:
Barbra--I'm not sure this particular project tests a scientific theory or law, so if that is your assignment, this project might not work for you. This project teaches the scientific method and is a quality control experiment. Companies do this sort of testing all the time to determine whether their products or new formulas work better than older formulas.
Barbra Robins on October 10, 2016:
What scientific theories or laws were in this project?
NiNi on September 26, 2016:
this is the best project I have ever seen I am sooooo doing this ;)

Cat Lover234 on March 27, 2016:
I thought it was great and my fav gum is fruity mentos
Ally on February 02, 2016:
HI, this week I have a stem fair and I've decided to do this project. I am so excited to do it.
christy king on January 25, 2016:
Nice i love this project
Sophia on January 10, 2016:
this is the project that im going to do it sound really fun cant wait ti find out what brand last the longest !
Virginia Kearney (author) from United States on November 24, 2015:
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!
Maddie Ruud on November 24, 2015:
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!
Virginia Kearney (author) from United States on September 25, 2015:
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)
Gina on September 24, 2015:
What is the independent and dependent variable ??
Brace Face on February 12, 2015:
I used this project and it was awesome. Sitting around all day chewing gum is fun. Now half of the people in my test had to get braces including me.
Nikki McCown on February 11, 2015:
I'm in eight grade and I have to do this project. It is really fun and I am enjoying it! :)
delainie Gonzalez on February 05, 2015:
I love gum even though I can't eat it. (:
Virginia Kearney (author) from United States on January 26, 2015:
Hi Tiffany--how about "longest lasting chew" or "Longest lasting gum."
Thomas on January 25, 2015:
I love gum
Mitzi on January 10, 2015:
I'm also doing this project for the 6th grade Science Fair
Silvia on January 07, 2015:
I like big league and doubble bubble
Amanda on January 05, 2015:
All kinds of bubblegum are my favorite
kisha on December 15, 2014:
i had a science fair in 4th grade and it was about gum and you can't eat the same gum or you will get tiered of it over and over again
Gordon Fisher from Connecticut, USA on December 10, 2014:
This is pretty cool! As for the gum with the longest lasting flavor I would have put my money on Trident Layers, although it wasn't included.
Ktm@yaooh.com on December 08, 2014:
I'm going to this for 5th and we have a lot to do it just so fun and the school I go to is the best lol
Virginia Kearney (author) from United States on December 02, 2014:
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.
Lorie on December 01, 2014:
What category would you say this falls under? Chemistry?
Rymom28 on November 24, 2014:
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!
Virginia Kearney (author) from United States on November 02, 2014:
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!
Laura Smith from Pittsburgh, PA on November 02, 2014:
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.
Mikayla on March 13, 2014:
The best part is you get to keep the rest of the gum:)
Hendrika from Pretoria, South Africa on January 20, 2014:
What a fun project? Chewing gum, who would have thought you can do it. I am surely going to tell my Granddaughter about it.
Alex on January 20, 2014:
This was so much fun
hakeem hurst on January 08, 2014:
I feel that this project is GREAT!!!!!!!!
Liz on October 26, 2013:
Virginia Kearney (author) from United States on October 11, 2013:
Love that you had this idea too! This was my kid's idea and they did it in 2005 for the first time.
clairewait from North Carolina on October 11, 2013:
Also, love the way you got your students to all chime in. Brilliant. Wish I'd been a Hubber when I was still teaching. I totally would have done the same thing. Haha.
clairewait from North Carolina on October 11, 2013:
This was totally my 6th grade science fair project in 1993. Did we go the same school?
Virginia Kearney (author) from United States on June 09, 2013:
If you look at the information in the article it tells you it used to be made from the chicle plant but now there are synthetic substitutes
Virginia Kearney (author) from United States on May 03, 2013:
So glad to know you did well at your science fair!
Timmy on April 29, 2013:
I like your project.
Virginia Kearney (author) from United States on February 26, 2013:
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!
Virginia Kearney (author) from United States on January 26, 2013:
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 on January 26, 2013:
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.
nansy.parra on November 23, 2012:
which has the longest gum
Virginia Kearney (author) from United States on April 12, 2012:
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!
