Science Fair Logbook Name Tegh: Topic: Write about the topic you chose. Why did you choose this topic? What do you hope to find out? I’m doing an experiment to test the acidity of different soda’s. I chose this topic because I wanted know how the food we consume could potentially affect our bodies. In this experiment I hope to find out how the acidity links to how healthy the drink is and how it may be affecting our bodies Testable Question How does soda affect marshmallows? What is the effect of soda on marshmallows? Which soda is dissolve the marshmallows the fastest ? I'm doing this experiment to see how acidic soda is to you because if I use marshmallows it will show if it dissolves quick it won’t take a lot of time to do the same to your stomach Background Information What questions/information do you need to find out about your topic? What is some important vocabulary? About crush. Crush is a soda brand that is owned and operated by Keurig Dr Pepper Did you know that crush was made by a chemist. About Coke. Coke is a soda brand owned and founded Dr.John S, Pemberton he is a pharmacist Coke was made with the syrup and the recipe was kept for years until was replaced which got lots a lot of backlash so they brought the old recipe back and they had it sense About Mountain Dew Mountain Dew was created,owned and founded by Barney and Ally Hartman as a mixer Background Information Research your topic and write about what you find out IN YOUR OWN WORDS.

(I do/change this…) (I think this will happen) (Why? ) *use info from your research or background knowledge to help explain) I think that the mountain dew will be the most acidic than coca cola and the least is crush and that the marshmallow will be quick to be dissolve and will make some of the sodas change there shade when you look at it Materials What materials will you use for your experiment? Be specific about amounts whenever possible. Coca cola Crush Mountain Dew Jars Marshmallow’ Tape Timer Procedure List the step-by-step procedure you will follow to conduct your experiment. Be as specific as possible and include exact measurements, quantities, times, etc. Tape marshmallows to a jar Fill jars with soda (1 cup) and start timer Turn off timer when it dissolves Experiment: Trial 1 Photos: Experiment: Trial 1 Observations/Notes: it grew a bit but There is something in the marshmallows that keep it from dissolving i think in trial 2 I will have to use a different variable to see if it will dissolve unlike the marshmallows. Data: (measurements) Coca cola Would not dissolve Mountain dew Would not dissolve Crush Would not dissolve Date: Why did it not work theory My theory is that the gelatin was the component that stopped it from dissolving because one time when i was at my friends house me and him were eating jello but he dropped some in soda while he was putting it away and then the next day (24 hours later) he called me and said bro i left jello in my soda The Research Theory I did my research and the only thing i found was soda fluffs witch use marshmallow fluff so i had to use a mix of the soda with some welch's fruit jelly snacks i had left over from halloween it sat there for days and i now know what happened.the gummies absorbed it and grew just like the marshmallows if you want more proof search up sprite gummy hack. So in conclusion the gelatin was the problem in the experiment Experiment: Trial 2 Observations/Notes: Data: (measurements) Coca cola mountain Date: Experiment: Trial 2 Photos: Experiment: Trial 3 Observations/Notes: Data: (measurements) Date: Experiment: Trial 3 Photos: Results: Chart Put your data together into a chart. Example: (you can change the chart) Trial 1 Trial 2 Trial 3 Conclusion My question was:how fast does a marshmallow dissolve in soda The answer to my question is: no it won’t even dissolve in soda because of the gelatin inside of the marshmallows My hypothesis was correct because: OR My hypothesis was incorrect because: of the gelatin inside because it won't dissolve in soda Extensions If you were to conduct this experiment again, what would you do differently? I would change the marshmallow to a real tooth Results: Analyze Look at your data and observations. Look for patterns and trends. Explain what happened in your experiment and what you found out: All in all it was a fail because of the gelatin because gelatin will not dissolve it absorbs the soda that was a key component I forgot while doing the experiment that could have helped before so i conclude that this was a big fail Results: Graph Graph your data for a visual display of your results. Use Google Sheets or another website and copy the graph onto this slide, or draw by hand and upload a photo. Ask your Science Fair teachers for help if you need it! Applications In what ways are your findings useful? Who could benefit from your results and how? What I was trying to do was to show how acidic soda can be but because of the gelatin in the experiment so i can’t help because it failed Extensions Because of the results of this experiment, I wonder… Describe further experiments that could be conducted to further investigate and understand your topic: I wonder what could happen if I changed the marshmallow to a jolly rancher or a tooth but that's all for next year to see CONGRATULATIONS!!
