The Scientific Method Essay Example for Free

The Scientific Method EssayThis experiment was performed by using a systematic antenna to identify six unknown substances. In the first half of the experiment six unknown substances were sight than measured by determining volume, muckle and immersion. The second half of the experiment the unknown were placed in a test tube and tested for solvability. It was determined that the six tubes contained c scoreee, potting soil, brown sugar, baby powder, baking soda, and powdered sugar. By the use of the scientific method all(prenominal) unknown subject could be identified. HypothesisThe table of contents of unknown samplers atomic number 18 as follows 1 coffee, 2 potting soil, 3 brown sugar, 4 baby powder, 5 baking soda, 6 powdered sugar.Material ListDigital Scale50 ml piston chamberSafety GogglesSpatula6 Test TubesMagnifierRubber StopperTest Tube Rack fool PencilTest Tube Cleaning BrushProcedure The unknown substances were removed from a bag. Next, volume, density, and draw we re calculated using small paper boats, a digital scale, and a formula which called to divide the mass by the volume. Then, the texture, shape and appearance of each substance was observed and recorded. Lastly, each substance was tested for solubility in distilled water.Data Table Calculating Density of isolated SamplesMass of UnknownSample (g)Volume (cm)Density (g/cm)Unknown taste-tester 1 = 0.41.3.31Unknown Sampler2= 0.51.5.3Unknown Sampler3=0.51.5.3Unknown Sampler4=0.81.3.61Unknown Sampler5=0.61.5.4Unknown Sampler5=0.61.3.46DiscussionBased off of observations of color, shape, and texture and smell hypothesis is accurate and correct for unknown samples 1-6.In conclusion based off of color, smell, and texture the hypothesis for unknown substances 1-4 are correct, but based off of these same observations substances 5 and 6 are questionable.Questions1. Which of the six measures in the experiment yielded quantitative data? What specifically ab tabu the measures was quantitative? vic enary data is data that can be measured numerically, out of the six measures in the experiment volume, mass, and density would be considered quantitative since these measures can be measured numerically unlike any other from the experiment.2. Which unknowns are you confident that you correctly identified? What specific test was crucial in confidence?I am confident that I have correctly identified unknown substances 1-4 based off of color,texture, smell and solubility these measures were crucial in my confidence of my hypothesis.3. One of the most important and unique steps in the scientific method is the ability to create a new hypothesis if your results do not support your passe-partout imaginations. What areas in your life, other than in science class, do you think this type of step would be laboursaving?I am a mother and frequently find myself in the kitchen cooking and trying out new recipes that taste good but are still nutritious (children can be real picky) I would say in terms of a new recipe that I am trying- If my idea is that my children would like to try something new I would test it out by serving it to them, and in the plate that my children do not like it I would try again maybe add some ingredients or take something out in hopes that the end result would be for my kids to enjoy the meal while getting all of the nutrition that kids need.4. What additional test could you perform to assist in the identification of these unknown samples?Melting, boiling, or even chemical test may be performed.5. Which of the seven tests performed was the most repugn?The most challenging test for me was the shape test, I found this most difficult because although I had the magnifier I still had issue distinguishing what it was that I actually saw as I was examining each substance, however once I examined each substance individually I compared what I saw and could most definitely see the difference amid large and small particles.
