Sand density lab
Sand Density Lab- Nick Schlosser
I. Overview- Finding the volume of regular shapes and irregular shapes using different methods like the water displacement method.
Procedure- See data chart
III. A.)With a ruler of calipers calculate volumes of regular and irregular objects- fill in chart. B.) Record data from another group to compare data for same object.
Preliminary questions- 1. Explain how you propose we go about measuring the volume of sand(as sand has air around it. What is the water displacement method, describe how you do i?- You put sand in first then you put water in a graduated cylinder then put hand on the end of it and shake it up until it has no air around it. And water displacement method is when you see how much the volume of an object is by having a cup of some sorts filled to the top then put the object in it slowly, then how much water bleeds out is the volume of the object.
Post lab questions-
What is the difference between a measurement and a calculation? Give an example from your lab work- A measurement is the numbers you pull of of the object and calculation is what you put those numbers into to get another answer, and with how we measured and object then got the water displaced and did mass over volume and calculated that out.
How do your results compare to the work of another group? Write out the name of the other group and their numbers. The numbers were different because we used different objects of the same material, like we both used iron but mason got 48.27 grams for a beginning weight when we got 108.15 grams, because they were different shapes or something, But the calculations we put those measurements in were the same though, and we both got different answers, i got 32.54 g/ml and Mason got 12.54 g/ml Explain the difference of your data from the other groups data?- The masses and and volumes were different causing the densities to be different because we used different sizes of the same type of
