Gummy Bear Lab Essay Example for Free

Gummy Bear Lab EssayQuestion- If the percent of the tightfistedness of a solution varies, will the amount of water gained or lost vary in a linear fashion?Hypothesis- If the concentration of a solution varies, then the amount of water lost or gain will not vary in a linear fashionPrediction- I suppose that the amount of water lost will not vary in a linear fashion. I think the water will vary like whizz mucilaginous bear would lose 4 grams while another would lose 6 grams while another would lose 3. 56 grams. Just numbers racket all over the place.Experiment-1. Materials neededa. 5 syrupy bearsb. 5 beakersc. A scaled. Distilled watere. flavourf. A cover for each beakerg. A paper to put on the scaleh. TweezersThe independent variable star is the salt in the water. The dependent variable is whether the amount of water lost or gained in the viscid bears varies in a linear fashion. The constants are the attribute of pastelike bear used in this experiment, the type of salt, t he 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. refuge proceduresinclude washing your hands before and after the experiment.Day 1 Get 5 beakers and 5 gummy bears. Put a paper on the scale and find the weight of the gummy bears. past put the gummy bears in each beaker and label the beakers A-E. Put 100 ml of water in each beaker. Pick a solution you ask 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 adjacent to 5 grams.Do the same 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 remain for 24 hours to see what happens . Day 2 Take the beakers out of the place they were in. Spill all the limpid 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 waste away and wash your hands.AnalysisObservations were that all the gummy bears lost their pale lily-livered 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 any(prenominal) looked like it lost weight. Errors were that a little bit of salt was enlargeed into the control sort 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 were 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 alter 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 affected 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 wa s done correctly.Other experiments that can be done are by taking a flutter and filling it with water. Then secure the paper towel on the jar with a rubber band. Make a water filled chamber to put food colouring drops it in and see what happens. The paper towel is the cell membrane and the food coloring is the water molecules crossing over 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.
