Gummy Bear Lab Essay Example for Free

Gummy Bear Lab EssayQuestion- If the percent of the concentration of a solution varies, depart the amount of water gained or preoccupied go away in a bilinear fashion?Hypothesis- If the concentration of a solution varies, then the amount of water anomic or gain will not vary in a linear fashionPrediction- I think that the amount of water lost will not vary in a linear fashion. I think the water will vary like angiotensin converting enzyme gummy absorb would lose 4 grams while other would lose 6 grams while another would lose 3. 56 grams. Just numbers any over the place.Experiment-1. Materials neededa. 5 gummy bearsb. 5 beakersc. A scaled. Distilled watere. Saltf. A cover for each beakerg. A paper to put on the scaleh. TweezersThe independent variable is the flavor in the water. The dependent variable is whether the amount of water lost or gained in the gummy bears varies in a linear fashion. The constants are the type of gummy bear used in this experiment, the type of season, the type of beaker, the type of scale, the cover, amount of water, and the amount of time the gummy bears have. The control is the beaker without the salt in it Beaker A. Safety proceduresinclude washing your hands before and after the experiment.Day 1 Get 5 beakers and 5 gummy bears. upchuck a paper on the scale and hazard the weight of the gummy bears. Then put the gummy bears in each beaker and label the beakers A-E. Put 100 ml of water in each beaker. decompose a solution you want each beaker to have. For this experiment the solutions were Beaker A- 0% Beaker B- 5% Beaker C- 10% Beaker D- 15%, and Beaker E- 20%. So to put the solutions into the beaker, first take salt and find the weight of it. It you want a 5% solution the salts weight has to be 5 grams or close to 5 grams.Do the identical for the other beakers. Of course, Beaker A will have no salt in it because it doesnt have a solution with salt. Cover each beaker with the same kind of cover and wait for 24 hou rs to see what happens. Day 2 Take the beakers out of the place they were in. Spill all the liquid out of all the beakers. Make sure to identify which gummy bear is which. It is best to do this one at a time. Take the gummy bear out of the beaker with tweezers. Put a paper on the scale and weigh each gummy bear. Record the weight. When you are done weighing each, throw the gummy bears and all uncivilized away and wash your hands.AnalysisObservations were that all the gummy bears lost their pale yellow color and turned into a clear color. Some gummy bears had salt sticking to it. Another gummy bear lost its shape completely and it looked like glob. Some gummy bears looked like it gained weight and some looked like it lost weight. Errors were that a little bit of salt was added into the control group Beaker A. Results from Alexiss group were that all the gummy bears gained weight and Justin told me that all his gummy bears also gained weight although I dont know what their solution w ere for each beaker or the difference from the final weight to the initial weight. Their results didnt vary in a linear fashion. Mathematical calculations were to subtract the final weight of the gummy bear with the initial weight of the gummy bear.ConclusionThe results of the experiment were that the water lost or gained didnt vary in a linear fashion. It went from one number to another. Even though the amount of solute varied in a linear fashion, the differences did not. They vary at a nonlinear rate. These results matched the hypothesis and proved it correct.Errors that happened in this experiment were that some salt was added to the control group Beaker A. This could have touched the dependent variable by gummy bear losing a little bit of weight because of the salt. The results from the other groups were that their results didnt vary in a linear fashion. This is consistent with my results because the difference in grams also didnt vary in a linear fashion. This means that my lab was done correctly.Other experiments that can be done are by taking a jar and filling it with water. Then secure the paper towel on the jar with a arctic band. Make a water filled chamber to put intellectual nourishment coloring drops it in and see what happens. The paper towel is the cell membrane and the food coloring is the water molecules crossing the cell membrane. Another experiment is by filling two beakers of water, making them full and labeling them. Then add salt to one beaker and mix it into the water until no more salt can dissolve. Put a carrot, celery, and 3 raisins in each beaker and see what happens in 24 hours.
