My topic is dissolving substances. I chose this topic because it seemed interesting. I also chose this topic because my parners, Catie and Courtney both liked this idea very much.
The question my partners and I tried to answer was, "when comparing peanut butter and marshmallow cream, which will stick better in Kool-aid, water, and vinegar?" We chose the topic dissolving substances because it seemed the most interesting out of all the things we had thought of. After considering the question we could use Catie said "We could put peanut butter and marshmallow crem in different liquids." We chose water, vinegar, Kool-aid, and hot water as the variables.
Do you know any facts about dissolving substances? I do and I will tell you about them. Cocoa, saly, and sugar dissolve in water. When a liquid can not dissolve something that is in it, it seperates from the liquid. Water is good for making and dissolving solutions. Items that are broken doewn usually dissolve faster than whole items. Turpentine is another good disolver. Turpentine dissolved in paint like drink mix dissolves in water. Turpentine is good for cleaning paint-stained fingers.
This is what we did to answer our question when comparing peanut butter with marshmallow cream, which stays longer under Kool-aid, water, and vinegar? This is what we did: First, we put peanut butter on the side of a cup of water. Next, we timed the peanut butter until it fell of the side of the cup. Then, we put peanut butter on the side of a cup filled with Kool-aid. Then, we timed it until it fell off the side of the cup. Then we put peanut butter on the side of a cup with vinegar and we timed it until it fell off the side of the cup. Next, we did the same things that we did with peanut butter, except we used marshmallow cream. Finally, we recorded our data.
These are some things I learned: Creamy Skippy peanut butter in Kool-aid, which was 21 degrees Celsius, took 4 minutes and 8 seconds to fall off the side of the cup. Creamy Skippy peanut butter in water, which was 22 degrees Celsius, took 16 minutes and 4 seconds to fall off the side of the cup. Creamy Skippy peanut butter in vinegar, which was 25 degrees Celsius, took 13 minutes and 52 seconds. Creamy Skippy peanut butter in hot water, which was 44 degrees Celsius, took 2 minutes and 27 seconds to fall off the side of the cup. JIffy marshmallow cream in Kool-aid, which was 21 degrees Celsius, took 3 minutes and 18 seconds to fall off the side of the cup. Jiffy marshmallow cream in water, which was 22 degrees Celsius, took 54 seconds to fall off the side of the cup. Jiffy marshmallow cream in vinegar, which was 25 degrees Celsius, took 6 minutes an 18 seconds to fall off the side of the cup. Jiffy , marshmallw cream in hot water, which was 44 degrees Celsius, took 1 minute and 11 seconds to fall off the side of the cup. I hope you enjoyed learning about this as much as I did!
I had fun doing this topic, but I needed more time to try some other things. These are the things I wanted to do, but did not have enough time: I wanted to try more substances like melted marshmallows, melted peanut butter, peanute butter and marshmallow cream mixed together, and the list goes on and on. I also wanted to use different liquids like orange juice, Coke, Pepsi, and many more. Here are some questions tou could use when you do KIC: How much time does it take for a mineral to dissolve in acid? How long will a mineral keep its form in vinegar? These are some great questions to use, and I would love to hear that you have used them!
