We decided to test the temperature of the sprite and mentos to see how high the soda sprouts with the different temperatures. We decided to make that our project because of how it was inexpensive, interesting it was,(and relatively fun doing),and not very time consuming. We were even going to drink all 3 once we were done and explain the taste exquisitely.
Our independent variable is the temperature of the sprite and the number of mentos we use on each one. We will be using 3 different sprites with 3 mentos each. We will put one in the freezer for 1 hour, boil another for 1 hour, and keep the last one in regular room temperature for 1 hour.
Our dependant variable is the height of the sprout (or geyser). We predict that the temperature of
We placed elodea plants into three different beakers and labelled them. Since, we are trying to find how temperature can affect the rate of production of carbon dioxide, we had to place them in different temperatures. So, we labelled the first beaker “Elodea heat” and placed it in a water bath that produced sufficient amount of heat. We labelled the second one “Elodea cool” which was placed in an ice bath filled with ice. The next one “Elodea RT” where the elodea was placed under normal room temperature without any interference. And we named the last one “No Elodea” where we placed no elodea in it and kept the beaker in a dark
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup
This experiment will show how the temperature of water will affect how quickly a Alka-Seltzer tablet will dissolve. (Rowland) This experiment seemed appealing to me because it sounded interesting to experiment with chemical reactions. “How does the temperature of water affect how quickly an Alka-Seltzer tablet will dissolve?”
Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. The molars range from 1-3.
In this experiment, we tested how the sugar cubes dissolve from different water temperatures. During the lab we made sure to make accurate and precise measurements, so what we did was do the same exact procedure to every section of the lab.

To continue the experiment further I can use a different source of light to test the intensity of light. For the food coloring experiment, I could use a different food color such as yellow or orange to test.
Doesn't everyone love the sudden eruption of a volcano or watching fireworks on the Fourth of July? There is something about the exciting human reaction to witnessing these explosions. Dropping Mentos candies into a diet soda to see how high the geysers can be a pure excitement. Is it a chemical reaction or a physical reaction? What causes the geyser to erupt? These are some questions that can be answered by a little research on the qualities of Diet Coke and Mentos.
Variables --------- During the experiments, the water will be heated using different spirit burners containing different alcohols. I will be able to change different parts of the experiment. These are the. Volume of water heated:
My experiment was if an egg was changed by cooking or freezing it will it affect how far it would fly. So I did the tests and my hypothesis was wrong. The frozen egg did not fly the furthest, the raw egg did. The raw egg every time went about 1-2 feet more than the frozen egg did. I think this is because when I froze the egg it gained weight and the raw egg stayed the same. This was enough to make the frozen egg not go as far. In fact the frozen egg flew the least amount of distance except for on the first launch where it came in second. This Experiment change but modified to be more exact by moving it into an indoor facility. This will help with not having to deal with wind or any other weather conditions.
Then, repeat steps 7-11 another 4 times but with the room temperature water. For the room temperature water just leave it in the room but try not to change the room’s temperature. 15. Try to put all your recorded data into a table for organization 16. Repeat the entire experiment for more reliable data.
Overall I think I carried out the experiment in a precise way and I took my time trying to make all my measurements as accurate as possible so that my data is reliable. Next time I will do more tests instead of just 3 so I have more results and so I could get a more accurate average. I will also do the experiment with more fruit juices to see if there are other fruits with a higher content of vitamin C. I will do an experiment to see if there is a difference in Vitamin C levels between fresh juice and store bought juice. I can also test different brands of juice to see if they have different levels of vitamin C.
Independent variables: The temperature of hcl gas will be decreased and increased throughout the experiment.
Methodology: A plastic cup was filled half way with crushed ice and mixed with four spoonfuls of 5 mL of sodium chloride. A thermometer was quickly placed inside the cup to take the temperature and the
The purpose of this study is to observe the rate of decay of two bananas at different temperatures and determine how temperature affects the rate of decay of bananas. I will perform this study by taking to equally ripe bananas and putting each banana into a plastic bag. Then I will label each bag to make sure when I am making my observations that I don’t mix up the bananas. I will put one of the bags with the banana in it into the fridge and the other bag will be put on my desk in my dorm room. I will record the temperature daily in each location to makes sure that the temperature isn’t changing. I will examine the bananas everyday at the same time and observe any signs of decay. I will take the observations at the same time to make sure there is equal time between each observation so the results aren’t affected. I will
