Abstract. An abstract is an abbreviated version of your final report.
Scientists have proven that gum chewing can help remove bacteria from our teeth because the friction from chewing gum rubs off many of the germs. However, this can never get rid of all the mouth’s bacteria. Sugar is like food for bacteria—the more sugar in the gum, the more the mouth’s bacteria will thrive. Fruit-flavored and other sugary chewing gums may remove some bacteria, but will cause their own bacterial growth in the mouth because of their high sugar content. Mint-flavored gums do an average amount of cleaning to the teeth because they generally have less sugar than fruity gums.
Chewing gum is tasty and fun. There are so many different brands and flavors to try! But what effect does it have on your teeth? You’ve probably heard some people say that chewing gum helps keep your teeth clean. You’ve also probably heard others say the exact opposite. How are we going to resolve this problem? We’re going to do an experiment.
Background research. This is the Research paper you wrote before you started your experiment.
· 9 Volunteers
· 1 Apple, cut into 9 slices
· 3 Cups
· Mint-flavored gum
· Cinnamon-flavored gum
· Fruit-flavored gum
· 9 Pre-prepared petri dishes with agar
· Cotton Swabs
· Timer or Stopwatch
1. Instruct each volunteer to eat a slice of apple. This is to introduce sugar to the mouth.
2. When they’re finished, have each volunteer chew a stick of mint gum for 5 minutes.
3. Gently swab each volunteer’s bottom gum line with a cotton swab about five times. Make sure you take your sample from the same gum line area for each volunteer. Consistency is important!
4. Spread the contents of each cotton swab into its own petri dish.
5. Label these three petri dishes “Mint”.
6. Repeat steps 1 through 5 for cinnamon and fruit-flavored gum, using three new volunteers each time. Label the petri dishes according to what gum was used.
7. Let the petri dishes sit in a dark area overnight.
8. Which gum do you think will clean teeth the best? Write down your guess, also called a hypothesis, in your notebook.
9. Examine the petri dishes the following morning.
10. Photograph your petri dishes and take notes describing each dish’s germ growth in your notebook.
Data analysis and discussion. This section is a summary of what you found out in your experiment, focusing on your observations, data table, and graph(s), which should be included at this location in the report.
Fruity gum will
have caused the most germ growth. Mint gum will have caused less germ growth.
Cinnamon will have caused the least amount of germ growth.
Ideas for future research. Some science fairs want you to discuss what additional research you might want to do based on what you learned.
