Experiment #1
Measurement, Length, Mass, Volume, Density, & Time
Objectives:
To make basic distance, mass, density, and time measurements.
To make calculations of volume and density, using proper units, and to practice using graphing software while graphing the relationship between the circumference of a circle and its diameter. Materials: stopwatch meter tape 3 rectangular objects metric ruler pencils metal bolt 500‐G scale graduated cylinder five circular objects

By having the length, width, and height measurements off by a little, the volume would be off by a huge amount. A small error in the hand measurements would grow by leaps and bounds in measuring volume. 3. Graphing data and the determination of π In this experiment, I measured 5 round objects of varying sizes. The objects I selected are a cup, a bowl, a soda can, a babies rattle, a CD.

Question: What is the slope of “C vs d” line? What does it represent? The slope of the “C vs d” line, according to the above graph, is 3.2548. This represents a ratio between the circumference and the diameter of a round object. Being that I used imprecise measuring devices my measurements are a little off. Although my ratio seems consistent in my graph. With a more accurate measuring device my measurement would be closer to π.
G. Percentage error formula: Percentage error = π = 3.14 Estimate = 3.2548 3.14-3.2548/3.14 = ‐0.0365 x ‐1 = 0.0365 x 100% = 3.65% My percent of error is 3.65%. 4 Density Measurements: determine the density of a metal bolt by water‐displacement method:
A, B & C: For this experiment first I weighed a metal bolt using a digital scale, getting a weight of 7.8 g. Then I filled the graduated cylinder with water to 10-mL. Next I placed the metal bolt into the cylinder and recorded the new volume. This reading was 12-mL.

## Measuring The Volume And Mass Of A Cylinder, A Sphere And A Wooden Block Essay

1377 Words | 6 PagesObjective This experiment will involve measuring the volume and mass of a cylinder, a sphere and a wooden block. Based on the mass and volumes of these objects, the density of these objects can be calculated. The equation for the density of an object is density =mass/volume. In the density equation there is a direct proportional relationship between the mass of an object and its volume. For instance, if an object has its mass decreased, its volume will also decrease. The experiment used a Vernier

## Mass Density Of An Unknown Metal Essay

1066 Words | 5 PagesThe goal of this experiment was to determine the mass density of an unknown metal. Five different vernier capillaries and double pan balances were used to measure the metal. The plan of action was to find the average density to reduce random error, in addition to, calculating the standard error to observe the reliability of proposed average. Ideally, the metal would identify more comparably with gold or aluminum. The concepts of mass density, standard error, average, one-dimensional statistics
