Experiment 2 Graphing and Measurements Graphs summarize numerical data efficiently and are usually casier to understand and interpret than columns of numbers. In this experiment, you will collect data and construct a graph that makes an effective visual presentation. Materials: Equipment metric ruler Chemical a kit with 5 pieces Procedure: Part I: Measurements on Rectangular Metal Pieces A kit with four regularly shaped pieces and one irregularly shaped piece will be provided to you. All pieces are made of the same material. For the each of the four regularly shaped pieces, make measurements of mass, length, width, and height. The thickness (height) is labeled on the envelope. Calculate the volume and the density of each piece. Part II: Graphing Linear Data Use the graph paper provided graph Mass (on y-axis) versus Volume (on x-axis). Title the graph and label both axes appropriately. Draw the best straight line through the points. Select a convenient set of units that will include this range of values. It helps to select units with subdivisions of 10, or 2 or 5 since the masses are in decimal units. Never use divisions of 3 or 4 for instance. The graph should take up most of the graph paper and remember that you do not have to start each scale from zero. In general, the scales on the x-axis and the y-axis do not need to start at 0. The first 3 examples are of inappropriately scaled graphs but the last one is best. idcal graph these three figures represent poor graphing technique Carefully plot the experimental points. Use a pencil because it is easy to make mistakes in this kind of plotting. Make small dots, and then draw small circles around them so that they show up clearly. Examine the data points carefully. Using a ruler or other straight edge, draw the "best" straight line through the data points. Don't do this too hurriedly - it requires some judgment. If the points are somewhat scattered, there should be equal numbers of them on either side of the line. Don't connect the dots!! When you 27

I need someone to help answer table 1 only mass, volume, y density and table 2 with a graph each table.
please read the procesures, thank you
