a. The main problem being investigated in this experiment is the different rates the color on a skittle dissolves when sugar is added to water. The experiment was to determine which amounts of sugar would affect the rate at which the color on a skittle dissolves. According to Little Bins for Little Hands, skittles are supposed to be able to dissolve in water (Littlebins, 2016). I did not know water could help the skittles dissolve faster, and I thought the sugar I added would help them dissolve at a faster rate. This experiment really caught my eye because I was personally really intrigued as to how the amount of sugar would affect how fast the color on a skittle would dissolve. I’ve never heard of anyone doing this experiment so I wanted to test it for myself to see what kind of results I would get. Whenever the skittle was dropped into the water it would sizzle, and the process of dissolving would occur. My hypothesis was “If the amount of sugar is increased, then the rate it takes for the color on a skittle to dissolve will decrease.” The experiment was all around very fun, however the results I collected were not what I was anticipating.

My results showed me that my hypothesis was rejected. The stirring I did at the beginning of my experiment may have affected the rate the color dissolved. According to Reference, whenever you stir a solution together, water and sugar in this case, it creates the opportunity for them to come into more contact with each other. Whenever I dropped the skittle in the beaker it may have come into contact with more sugar, but when it dropped all the sugar landed in one spot so it may have lost some contact. My hypothesis was completely opposite because as I added more sugar to the water, the rate it took for the color on the skittle to dissolve increased. My new hypothesis would be, “If the amount of sugar is increased, then the rate it takes for the color on a skittle to dissolve will
Many people don't understand the effects on peppermint candy to the brain's reaction time. The experiment is telling if peppermint candy has an effect on reaction time. Reaction time can be affected by many things such as their normal reaction time, eating peppermints, a volunteers nervous system, a person's defects, or their genetics.
Hypothesis: The Alka Seltzer will dissolve fastest in hot water and slowest in cold water.
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?”
The lab experiment did prove that Crayola colors are not of pure substances but rather a mixture of specific color compounds needed to produce said colors. The experiment also proved that different color pigments have different densities (the lighter ones moved up the filter paper with the water, while the heavier ones adhered to the filter paper longer.)
Different experiments with different strategies: Experiment 1: Investigating the rate of dissolving in various temperatures. Control Variable: 1. The solute is the same: sucrose;C12H22O6(sugar) 2. The solvent is the same: water; H2O 3. The mass of sugar is the same: 0.5 g 4.
My science fair project is to find the solubility of salt and sand.Solubility is the measure of how much solute can dissolve in a given solvent at a given temperature.A solute is the part of a solution that is dissolved by a solvent.A solvent is the part of a solution that is usually present in the largest amount and dissolves a solute.A solution is a mixture containing a solvent and at least one solute that has the same properties throughout; a mixture in which one substance is dissolved in another.
...is for this experiment is: “If you increase the amount of drops of bleach mixed into a blue dye solution, then the total amount of time for the blue dye in the solution to disappear will decrease.” In other words, I think that the blue dye in the solution will disappear faster when you increase the amount of bleach. The research that I gathered helped me understand better of why and how I am going to do my experiments in the way I am doing them. It also supports my hypothesis. It supports my hypothesis because I found out that there is an active ingredient in bleach known as the hypochlorite molecule. This molecule helps break the bonds in pigment molecules so I think that the more bleach used, the faster the bonds will break apart. In this experiment, I will be finding out how much dye are mixed in sports drinks and what is the reaction rate of bleach and blue dye.
If the concentration of sucrose increases, then the mass of the potato will decrease. However, if the concentration of the solution in the beaker is less than that of the potato (such as distilled water), then the mass of the potato will increase. So, as the concentration of sucrose increases the rate of osmosis increases.
Conclusions: There is a pattern on the graph, and data table, which shows that as the concentration of the sucrose solution increases, the potato's percentage change in mass decreases.
The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.
Technically, all they’re doing is taking the dyes of the 2 green M&M’s/Skittles, then in a ⅛ tsp of salt and 3 cups of water, mixed together, in a jar/glass, you put the filter paper on with a binder clip that has the skewer/straw going through it (on the filter paper, there are dots drawn on with a pencil, at the 2 and 4 cm mark, then drawn over with a toothpick dipped in the dye that came off the candy). After you follow all these steps, you start to see the different color dyes that have been mixed together, separate from each other.This helps us answer the problem statement, because after all of this, you will have separated it successfully, and then you can see what the candy is now. They discovered that what they wrote in the hypothesis, came true.
To test this, we set up two experiments. The first experiment we set up had three cups. In each cup a potato slice and a different liquid was put in. In the first cup was filled with distilled water. The second cup was filled with salt water and the third was left empty.
Using the scissors, cut a 5cm piece of a straw and wrap two separate lines of copper wire around the piece of straw at both ends, make sure that there is at least 5cm remaining of the copper wire after it is wrapped around the straw (like in the image to the right)
To make it a fair test I will test each concentration three times and use the average. My tests will be accurate as I will be using a very accurate scale and precise syringes. To make my experiment accurate I will be using distilled water to make my sucrose solutions so there are no impurities that may affect my experiment and I will also measure my results to two decimal places. To make my experiment safe I will use goggles.
My Science Fair experiment is based on four main products, ibuprofen, acetic acid, bleach, and bread. The name of this is experiment is "Bread vs. Chemicals." The goal of this experiment is to see what chemical bread can survive in the longest. I will do multiple trials of each type of chemical and record results promptly. I am going to have three containers, one for each chemical and place a piece of bread in each and see how long the bread can survive without falling apart to determine the results. This experiment falls under the category of food science. Food science is considered to be a broad topic that coincides with scientific principles and foods to better understand them. Maillard reaction is quite often referred to as the
