was laboratory techniques and measurements. The purpose of this lab was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature‚ time

Abstract Measurements are all subject to error which leads to the uncertainty of the result. Errors may come from systematic errors (deterministic error) or random error (not deterministic error). In this experiment‚ the group measured the diameter of sphere using different kinds of measuring devices (foot rule‚ vernier caliper‚ and micrometer caliper) in order to achieve accuracy in the scientific measurements. After experimenting‚ it was revealed that the micrometer caliper has the lowest percentage

Experiment 1: Errors‚ Uncertainties and Measurements Laboratory Report Abstract The success of an experiment greatly depends on how the group is able to execute it and how precise and accurate their results are. In this matter‚ errors and uncertainties in measurements are of great factor. In this experiment‚ the group was able to classify the causes of such errors and which measuring device is more precise and accurate than the other. These were obtained by measuring the diameter of an iron sphere

Dr. Abdalla Measurement of Length‚ Mass Volume and Density Introduction: All science is concerned with measurement. "MEASUREMENT" is the determination of the size or magnitude of something "Or" The comparison of unknown quantity with some standard quantity of the same rates is known as measurement. Due to this fact we have standards of measurement. Since the precision of all measuring instruments is limited‚ the number of digits that can be assumed as known for any measurement is also limited

Earth by applying a free fall process. Objective The objective of this experiment is to validate Newton’s Second Law of motion. In experimenting the Law the measurement of acceleration of gravity was used by measuring the distance a dropped ball travels for a specific amount of time. Procedure First‚ measurements were taken of the distance from the stairway from the third floor to the ground and then from the fourth floor to the ground. The two points would be recorded as y which

“Basic concepts of educational measurement and assessment.” Summary Measurement‚ Evaluation and Assessment‚ this are the three important things that a learner undergoes for the facilitator to determine a valid and reliable result of achievement. But what is the difference of the three? Can we really measure achievement? If yes‚ then how can we make sure that it is valid? There are different kinds of evaluation and assessment‚ it is not just a series of test‚ continuous quizzes‚ seat-work and
