My topic was Dissolving Substances. My partners were Maddy and Catie. We chose this topic because we wanted to learn more about dissolving substances. We also chose this topic because we thought it was very interesting. The question I wanted to investigate was, when comparing peanut butter to marshmallow cream, which will stick longer or dissolve first under different liquids? My partners and I thought of the question by choosing a topic. We wanted to pick a topic about something we didn’t know about. Then Catie said, How about we use Skippy peanut butter and marshmallow cream, we can see which one will stick to something longer or dissolve first.” Maddy and I thought it was a good idea and we all decided we would use that question.
Water dissolves some things more easily than other things. Cocoa, salt, and sugar dissolve easily in water. Soap dissolves in water, which is good for washing clothes and dirty faces- even blowing bubbles! When water can’t dissolve things, they separate from the water. Items that are broken into small pieces generally will dissolve more quickly than the whole items. Turpentine is a good dissolver. Pain dissolves in turpentine like a drink mix dissolves in water. These are some things that dissolve easily.
The process I went through to answer my question was I put the Skippy peanut butter in a cup. Next, I poured a liquid in. (Kool-Aid, water, 44 degrees Celsius water, and vinegar) Then I watched the clock until the Skippy Peanut Butter fell off or dissolved. Finally, I wrote down the data. I repeated this process 3 more times using the different liquids. After I did the experiment with peanut butter, I did the same thing with marshmallow cream. I also did this experiment 4 times total.
During my investigation, I learned a lot. One thing I learned was that substance 1, Skippy Peanut Butter, sticks to the side of a cup under 22 degrees Celsius water for 16 minutes and 4 seconds. The second thing I learned was that substance 1 sticks to the side of a cup under 44 degrees Celsius water for 2 minutes and 27 seconds. The 3rd thing I learned was that peanut butter sticks to the side of a cup under 22 degrees Celsius Kool-Aid for 4 minutes and 8 seconds. The fourth thing I learned was that, under 25 degrees Celsius vinegar, peanut butter sticks to the side of a cup for 13 minutes and 51 seconds. These are the things I learned about substance 1, Skippy Peanut Butter. I also learned a lot about substance 2, marshmallow cream. One thing I learned was that substance 2 sticks to the side of a cup under 22 degrees Celsius water for 54 seconds. The second thing I learned was that marshmallow cream sticks to the side of the cup under 44 degrees Celsius water for 1 minute and 11 seconds. I also learned that marshmallow cream sticks to the side of a cup under 21 degrees Celsius Kool-Aid for 3 minutes and 18 seconds. Another things I learned was that, under 25 degrees Celsius vinegar, marshmallow cream sticks to the side of a cup for 6 minutes and 18 seconds. The most important thing I learned was that Skippy Peanut Butter sticks longer then marshmallow cream.
If you want to use my topic there are a lot of different experiments you can try with Dissolving Substances. One thing you could try is which substance; sand or salt will dissolve first. Another idea is will salt dissolve in hot water in at least 4 minutes. Some things that my group and I wanted to try were very interesting. We wanted to know how long it would take for our substances to dissolve in warm Kool-Aid, warm Vinegar, sprite and Pepsi. I really enjoyed doing this experiment.
