Alt Measurement Lab.docx Download Alt Measurement Lab.docx (105 KB) ALTERNATE MEASUREMENT AND UNCERTAINTY LAB Volume Units and Scales Observe the measuring cup below. There are three scales: cups, fluid ounces (oz.) and milliliters (ml).

Calculate the uncertainty for all scales on the measuring cup. Uncertainty of a scale is just half the value of the smallest graduations. Choose any two adjacent graduations for the upper and lower values. Use the formula: Uncertainty = (Upper graduation – lower graduation)/22. Fill out the modified Activity 2 table below: Scale in ml Scale in oz. Scale in Cup supper adjacent graduation Lower adjacent graduation Uncertainty 3. Create a conversion factor to convert from fluid ounces to milliliters. If you fill the measuring cup to a given height, then you can read off the volume in cups, fluid ounces or milliliters. The positioning of the scales allows you to convert between units. A. Compare the milliliter (ml) scale against the fluid ounce (oz.) scale and choose the pair of ounce and milliliter graduations that are closest to being directly opposite each other. That is, if you filled the measuring cup to that volume, both lines indicate that volumes. Write the fluid ounce volume here: Fluid Ounces = ______ oz... Write the milliliter volume here: Milliliters = ______ mild. Calculate the ml to oz. conversion factor by dividing your ounce value by the milliliter value to oz. conversion = Fluid Ounces / Milliliters. Write your ml to oz. Conversion factor here: ______ oz./mlf. Calculate the oz. to ml conversion factor by dividing your milliliter value by the ounce value Oz. to ml conversion = Milliliters / Fluid Ounces. Write your oz. to ml Conversion factor here: ______ ml/oz.h. There are 0.033814 fluid ounces in one milliliter. There are 29.5735 milliliters in one fluid ounce. Based on your calculations, what does this say about the accuracy of the scales printed on the measuring cup? Mass, Displacement and Density Materials:1. Four dollars-worth of nickels. Get these from you bank. Any kind of coin for which you can find the weight will work for example, the British 20p since it weighs 5g like the US nickel.2. A small cheap, lightweight, thin-walled disposable paper or plastic cup. The smaller the cup, the fewer nickels you will need. Seven to nine-ounce cups work well.3. A small measuring cups. See my image of a measuring cup above.4. A pot or bowl large enough to fill with water to a depth greater than the height of the cup. Procedure:1. Fill a plastic cup to the brim with water, carefully pour the water into an empty measuring cup and read off the volume. Write the cup volume below. Cup Volume = ______ ml2. Fill a bowl of water and place the empty cup upright on the top of the water. Use your hand to keep the cup from tipping. You will not need to steady the cup after you add some nickels. SIDE NOTE: If you are careful, and depending on the kind of cup, you may find you can cause the empty cup to float on the water. The cup will barely sink into the water. The fact that an empty light-weight plastic cup does not displace much water is important. It makes the math a lot easier. Give it a try, but empty and wipe off any water that gets on the inside if it tips over.3. Add about ten nickels to the bottom of the cup and put it in the bowl of water such that it floats without tilting. You may need to shake the coins around in the bottom of the cup to distribute their weight evenly. 4. Carefully add nickels, one by one, to the floating cup. Count the nickels as you add them. The cup will sink as you increase the weight inside the cups.5. Be extra careful as the lip of the cup approaches the surface of the water. Cup wobbling can cause ripples which may cause the cup to sink prematurely. Stop adding nickels when the cup sinks below the surface of the water.6. Record the number of nickels added. Dry off the cup and nickels if you wish to repeat the experiment. Write the number of nickels added below. Number of Nickels Added = ______7. Calculate the mass of all the nickels you added and write your answer below. Nickels weigh 5.000 grams so Mass of Nickels Added = Number of Nickels Added x 5 Mass of Nickels Added = ______ g SIDE NOTE: If you were to repeat this experiment, but fill the cup with water instead of nickels, then the cup would only sink when you have filled it to the brim with water. Give it a try and see for yourself. You will have to steady the cup because it will be more likely to tip. The downward force needed to cause the cup to sink would be the same for water and nickels, so the weight of the water needed to cause the cup to sink would be the same as the weight of the nickels you added. You can calculate the density of water since you know the weight of a known volume of water.11. Calculate the density of water. Write the density of water below. Density = Mass of Nickels Added / Cup Volume Density = ______ g/ml Summary of Results: Write a brief description of what you did. How accurate are the markings on a measuring cup? Your density calculation should be 1 g/ml. Was it? Explain what went wrong if everything did not work as expected. Paste image of you with your experiment here:
