Variables:
Independent: the type of water we use.
Dependent: is the size of the gummy bear after it was soaked in regular water, salt water,baking soda water, and vinegar.
Constant: the dependent variable was the size of the gummy bear after it was soaked in regular water, salt water, baking soda water,and vinegar.
Evidence:
In my data table it shows that the gummy bear put in water grew 0.5cm more than the other ones put in the other liquids.
Resonong:
The gummy bear in water grew bigger because the water has minerals in it so it can grow more, I know that the one in water is bigger because in the data table it showed the amount of change and the gummy bear in the water grew 0.5cm more than the other gummy bears put in liquid.

In the 1st day it showed that the gummy bear put in vinegar was getting bigger but over time the gummy bear in water grew even more bigger as the gummy bear in vinegar started disintegrating slowly, and parts of the gummy bear started falling off.
Next testable question:
Does the gummy bear change if it gets put under a lamp?
Does the gummy bear gelatin affect the process of the gummy bear experiment?
Hypothesis:
If you put the gummy bear in Vinegar it will not get bigger also if you buy it in the baking soda it will also not get bigger. The water will make the gummy bear get bigger because of the material that it made by the gummy bear.
Procedure:
1.In each of the four - 100 ml beakers or cup:
Pour 50ml of WATER into into one beakers or cup
Pour 50ml of VINEGAR into one beaker or cup
Mix 50ml of WATER with 15ml (1 tbsp) of BAKING SODA in one beaker or cup
Mix 50ml of WATER with 15ml (1 tbsp) of SALT in one beaker or cup
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup Onto the labelled sheet of paper under the correct heading. Let sit for one
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
10cm3 of 1 molar solution. I will use 3 of each solution to ensure that
neutralize 35ml of our base. Once we weighed out the KHP we then dissolved it
4. Pour about 300mL of tap water into the beaker. Set up a hot-water bath using a hot plate, retort stand, and thermometer clamp. Alternatively, use a Bunsen burner, retort stand, ring clamp, thermometer clamp, and wire gauze.
So the experiment will be based upon the movement of water. The first potato chip will be placed in a zero percent solution. I believe that this will increase the mass. I believe this because the zero percent solution has a lower concentration than the cell sap inside the potato. The potato takes on the water through osmosis and the cell pushes out from inside the cell making it swell and become more rigid.
Regarding the densities of Coke and Diet Coke, I believed that the density of coke would be greater than the density of Diet Coke. Because the content of Coke contains more sugar than Diet Coke, it would contain more mass and since density is mass dependent, Coke would be denser than Diet Coke. From the results of the experiment, there was a slight difference between the densities of Coke and Diet Coke. The measurements obtained from the pipette and the graduated cylinder demonstrated that Coke is denser than Diet Coke while Diet Coke was shown to be denser than Coke using the burette. With the pipette, the average density of Coke is 1.02 and the average density of Diet Coke is 0.99. With the graduated cylinder, the average density is 0.976968 and the average density of Diet Coke is 0.95. With the burette, the average density of Coke is 0.99 and the average density of Diet Coke is 1.0. Among the three instruments, the most precise was the graduated cylinder and the most accurate was the volumetric pipette. Since density is defined as mass/volume, changing the volume of Coke or Diet Coke would have changed.
When doing this experiment I was able to see the effect of different concentrations on the rate of osmosis, each was done by measuring the initial mass and length of the potato cylinder and after osmosis, the results were conducted to show that as the sucrose concentration increases the rate of osmosis also increases as I said in my hypothesis thusly making a direct decrease in mass.
Plan 1. Collect 4 different sized beakers 2. Boil some water in the kettle 3. Pour 50ml into each beaker 4. After 1 minute check temperature 5.
Potentially, salt will make the solutions more concentrated and, in turn, cause the gummy bears to shrink and decrease in mass. The salt water will probably have a high enough concentration of solute (the salt) to make the gummy bear hypotonic or isotonic to the sugar water. Salt will probably have a much stronger and more noticeable effect due to its chemical composition. As it is held by an ionic bond (complete -/+ charge), unlike sugar’s covalent bond (much weaker and easier to break), making salt more capable of forming a hypertonic solution, with a much more concentrated surrounding around the gummy bear, causing it to shrink and decrease in mass. Through osmosis, the water molecules are going to move to the area with more solute or molecules in it to even out the number of water molecules in both the salt water and inside the gummy bear. The water will leave the gummy bear and move to where there are more salt molecules. Next, using much larger cups and increasing the interval between each solute amount to produce a remarkable effect. Showcasing osmosis on a much larger scale will definitely portray the entire process of osmosis in a much better manner. However, we must also find much larger gummy or another brand that can withstand these new, overwhelming conditions. This will also make the gummy bears much easier to handle, providing better data. Lastly, I would also suggest trying other types of candy. Although not all candies have semi-preamble shells, like gummy bears, I think it would be interesting to examine how other candies react in a similar environment (salt, sugar, and pure water). As I think most sugary candies will end up dissolving, I believe that such an experiment would showcase the true the characteristics that gummy bear the special cadies that they are. Subsequently, we can examine how gelatin plays its role in making the bear expand.
Wash the petri dish with some (perhaps 10cm3) of the 250cm3 distilled water so that all of the solid is used and place the washings in the beaker also. Then pour the rest of the distilled water. 4. Stir with glass rod so that the solid is fully dissolved. 5.
Does the mass of a substance, borax, sugar, or Epsom Salt, affect how wide a crystal will grow? The hypothesis is,”If crystals are grown in borax, then the crystal will have a bigger width than the crystals made with Epsom Salt and sugar”. In this experiment, the independent variable is the mass of the substance added to water, such as borax, sugar, or Epsom Salt. The dependent variable is the width of the crystals after having seven days to form. Some control variables are using the same type of jar, the same measurements of water, and the same amount of pipe cleaner put into the jar. The control group in this experiment is the standard recipe for making each crystal. The experimental group is the crystals made with the other
In a 100ml beaker place 50mls of water, measure the temperature of the water and record this initial temperature onto a table. Set the timer and add one teaspoon of Ammonium Nitrate to the water, stir this continuously until the Ammonium Nitrate has dissolved.
In this experiment, the question “What is the effect of the viscosity of honey in a honey tube (85%-100%) on the final
of distilled water. For the 1M solution I added 50 cm3 of HCl and 50
We decided to use 2 minutes, as this gave the best results. We repeated the experiment fifteen times, firstly heating 50cm3 three. times, then add 25cm3 of water each time, so from 50cm3 to 350cm3. After each repetition we rinsed the beaker so as to make this a fair. experiment.
