Spill The Marbles! Problem: The purpose of this laboratory study is to determine an accurate method of finding the correct issue of stains in the container. Hypothesis: If we can find an fare tummy of the marbles, we can start the concourse of the empty container from the mass of the honorable container, and divide the difference by the average marble mass to then calculate the number of marbles as accurately as we can. Procedures: Mass empty marble container on the four-beam balance. Average the masses by first adding them together, and then dividing by the number of containers. Mass bounteous jar of marbles on the four-beam balance. Count out twenty random marbles, and place them in a urge gravy holder. Mass the marbles and the weigh boat on the four-beam balance. Record the total weighting, and then subtract the weight of the weigh boat. Divide the difference by twenty, in rescript to find the average of a case-by-case marble. take on move 3-6 at least 8 times. Add up all(a) averages, and then divide by the number of averages, in connection to find the absolute average mass of a wizard marble. Subtract the average mass of the empty containers from the mass of the container full of marbles. Divide the difference by the average found in step 8. Record answer. It is the calculated number of marbles in the container.

Data/Measurements: |Test Number |1 | | |1 kg | 185.27g (mass of empty container 1) + 187.35g (mass of empty container 2) 2 =186.31g (average mass of empty contain ers) 7600 g (mass of container with marbl! es) 186.31 g (average mass of empty containers) =7413.69 g 5.077 g (average general mass) = 1460 marbles Percent fault: 1516 marbles (actual) 1460 marbles (experimental) x 100 = 3.69% error 1516 marbles (actual) outcome: Some practicable sources of error could be an unbalanced scale,...If you indigence to get a full essay, order it on our website: BestEssayCheap.com
