Solution Effect on Gummy Bear/Cell Size
What are the effects of different solutions on the size of a cell? To find a solution this problem my group conducted an experiment/lab. The variables changed (Independent Variable) were the solutions, and the results were the change in size of the gummy bear/cell (Dependant Variable). The control group,to compare our results, was a gummy bear that was not put into any solution. The standardized variables were the color of the gummy bear, the same brand of cup, the amount of solution in each cup, and the amount of time each gummy bear spent in the solution.
The materials my group used were three identical plastic cups, four gummy bears of the same color, one plastic spoon, one roll wax paper, one sharpie marker, one roll plastic wrap, one graduated cylinder, 25 mL super saturated salt solution, 25 mL distilled water, 25 mL 80% sugar solution, and one 12 inch ruler. The procedure my group made follows these steps.

Measure the length, width, and depth of one gummy bear on wax paper with the ruler.
Label the cups to with the sharpie to correspond with the three solutions, supersaturated salt, distilled water, and 80% sugar solution.
Place each gummy bear into each labeled cup
Add 25mL of each solution to the corresponding cup.
Cover the top of each cup with enough plastic wrap to prevent evaporation.
Wait 24 hours to let the solution react with the gummy bear
Remove plastic wrap/tinfoil.
Remove gummy bear from each cup with the plastic spoon and place on wax paper
Record the length, width, and depth of the gummy bear (Quantitative) along with the color of the bears (Qualitative). Record this data in a data table after the first 24 hour
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.
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.
Day 1: (b) Put the bear in a cup labeled with your names, class period and liquid. Add 50 ml of water to the cup and allow it to sit for two days
Adding 1/4 cup of sugar once the water is boiling and stiring until it dissolves completly.
of each in each test tube. (Table below showing how I am going to make
1. Assembled the test tube rack with 4 test tubes. Placed 7.0mL of potato solution in each test tube. Gathered 4 of each 300mL beakers filled about half filled with tap water for the water baths.
The control variable influenced the results that we got in the bubble gum lab. First of all, getting gum stuck in your teeth or braces impacted the outcome. If it gets stuck in your teeth, the chewed mass would be lower than it should be, and would result in a higher percentage of sugar. This could explain why our groups percentage were higher than the company's control for the Bazooka gum by 1.3%. Also, the rate at which someone chews the gum affected the data, and might be the reason that Super Bubble’s percentage is low. I was chewing Super Bubble with my braces, and with my braces, I might not have been chewing as fast as I should have been. This wouldn’t have dissolved all the sugar, and would make the percentage lower than the control
Materials: 9 eggs, Vinegar, Water, 9 containers, Easter Egg dye Kit, red, green, and blue food coloring(1 of each color), red, green, and blue Kool-Aid packets(1 of each color)
The test will have problems of multiplication and division at least twenty problems will be in the sheet. This test will be timed and the two times will be compared and analysed. The person is not allowed to use a calculator but is allowed to use a pencil and paper to work out the problems by hand. The dependent variable is the gum which i believe will be affected while taking the test. The independent variable is the level of the test taken the test will not affect the person because the level of problems will be the same as the first test and the time
in 5cm³ of water and add 4cm³ of ethanol. We had tom pour this mixture
Third, grab the left edge of the Kool-Aid packet between your thumb and index finger. With your other hand, begin peeling the upper-left corner until the entire top of the envelope is removed. Next, dump the contents of the envelope into the pitcher. Notice how the powder floats before settling on the bottom of the pitcher. Then, take the measuring cup and scoop two cups of sugar into the pitcher as well. At this point, adding the water is a crucial step. Place the pitcher under the water faucet and slowly turn on the cold water. If the water is turned on too quickly, powder will fly all over when the initial gusts of water hit. After the pitcher is filled within two inches of the top, turn the water off and get prepared to stir. With the wooden spoon submersed three-quarters of the way in the liquid, vigorously stir in a clockwise motion until all of the powder is dissolved.
Identifying the Controlled Variable- The controlled variable was the cup without any material to insulate it.
My dependent variable is density, which is what the eggs will be measured and will answer my question. Density is what we use to measure the mass per volume, and I will be putting eggs into water in order to measure density. The density will determine which type of egg; raw, hard boiled, rotten, or frozen, will have the most volume and least when put in water. This variable is very helpful as well, and was one of the reasons I decided to do this project, which was to be better at it. My research will mainly have to do with density, since it is the only science concept I’m doing, so it will be simple to research about. Also, I must learn the right equation for it, which is d=m/v. Besides the word density, the dependent variable of my examination also has a couple of vocabulary words. The words least and most also pertain to this type of variable, because of my research question, which ask for which type of egg has the least and most density. Same and different also go with both my question and dependent variable, only because I ask if some are the same or different. Calculation will be another one as well, because I will be calculating the density of the four eggs. My project has a ton to do with density, so it will also be a major subject in
Prepare silica gel column. Add 6 g of silica gel in 20 mL of hexane to make a slurry. Block column with small piece of glass wool, add 5 mL of hexane and then add the silica slurry up to the 10 cm mark.
For my lab experiment, I will be using 7 products throughout my demonstration. I could use as many products that I want, however 7 is a common amount to start with. Every product will be measured according to the amount that the cup can hold. To conduct my experiment, I will be pouring the products into 2 ounce cups and will construct the column th...
