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 are watching: Which gum last the longest science fair project


*

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 one: Choose a variety of brands and guess which one will have the longest lasting flavor.

Step 2: Gather some family and friends to chew gum with you! We had everyone stay around a table reading comic books. You could have researchers watch a movie, too.

Step 3: Hand out gum, get the timer ready, and say "Ready, Set, Go!" to start everyone.chewing.

Step 4: Have each person tell you when the flavor runs out. Write the time in minutes and seconds on your chart.

Step 5: When everyone's flavor has run out, start again with another type of gum!
