Procedure Part I: Circumference vs. Diameter for circular objects s = Eh b e R B. 9. Circumference Locate 3 cans, each with a different circumference/diameter. Label the cans as Can 1, Can2, and Can 3. Using a ruler, measure the diameter of the top of Can 1 in centimeters. Be sure to report your data using the correct number of significant figures for your measuring device. Measure the diameter of Can 1 twao mare times, for a total of three trials. Record your measurements in the appropriate data table on the Lab 3 Warksheet. Calculate and record the mean diameter for the three trials. Repeat Steps 2-5 for Can 2 and Can 3. Using a tape measure, measure the circumference of Can 1. Be sure to report your data using the correct number of significant figures for your measuring device. Mote: If you do not have a metric measuring tape, find a piece of paper (or sting/yarn) that is long enough to wrap around the entire circumference of the can. Mark the paper (or cut the stringyarn) where it meets its beginning on the can. This will make the length of the paper {or string/yarn) the same as the length of the circumference. See example below, using a ribbon to measure the circumference of a circle: WMeasure the circumference of Can 1 two more times, for a total of three trials. Record your measurements in the appropriate data table on the Lab 3 Warksheet. 10. Calculate and record the mean circumference for the three trials, 11. Repeat Steps 7-10 for Can 2 and Can 3. 12. Plot the mean circumference (y) vs mean diameter (x) for each can on a line graph. (You can plot the graph by hand on graph paper or you can plot the graph in Excel). Paste the image of your graph of the Lab 3 Worksheet, 13. We expect the data points to lie in a straight line (or pretty close). 14. Identify 2 points (different than your data points) on your best-fit straight line (or trendline). 15. Record the x (diameter) and v (circumference) value for the two points on the Lab 3 Worksheet. 16. Calculate the slope of the trendline. Record the value on the Lab 3 Worksheet. Slope = [yz vil (%37%,) When plotting your graph, some things to consider when constructing a graph: a. Identify the variables that you are going to plot, and decide which axis you want to plot each varlable, b. Determine the variable range and the scale of the graph. The scale and range should be chosen so that the graph fills up most of the avallable space on the page. c. Label and number each axis. Remember to Include the correct units on the axis. d. Plot the data points, e. Draw the graph, Do not connect the data points like a \"connect-the-dots\" picture, Draw the line that \"best fits\" the data points. f. Title the graph. Procedure = Part Il: Reporting Your Results 1. Create a data chart for your survey results (Part 4 - Sclentific Method Assignment). 2. Insert your data chart in the space provided an the Lab 3 Worksheet, 3. Based upan the type of data you collected, create a graph that best represents your results, 4, Insert the graph of your data in the space provided on the Lab 3 Worksheet, Submit your completed Lab 3 Worksheet by the due date indicated for the assignment. SCIE 211 Lab 3: Graphing Data Instructions Introduction The purpose of graphing in science is to examine the relationship between variables. A good hypothesis predicts how the two variables are related; a graph of the experimental data can help support or disprove the hypothesis. The relationship between variables can be complicated. While all graphs have numbers and labels to identify the data, there are many different kinds of graphs. The five most common types of graphs are: line graph, scatter plot, bar graph, histogram, and pie chart. Choosing the best type of graph to display your data is critical to helping you finds trends and make new discoveries. Using the wrong type of graph may hide the story your data is telling. Additionally, there are many ways we can be fooled or mislead by a graph. Some common misleading iterns we need to watch out for include: scales that do not begin at zero; scales made very small to make the graph look very big; scale values or labels missing from the graph; incorrect scales placed on the graph; pieces of a Pie Chart that are not the correct size; oversized volumes of objects that are too big for the vertical scale differences they represent; size of images used in Pictographs being different for the different categories being graphed; and, graphs being a non-standard size or shape In this lab, you will practice graphing and analyzing data by considering the simple case of a linear relationship between variables. ou will also graph the data you collected for Part 4 of the Scientific Method assignment.
