5. Graphs and Charts
Form a table or chart to display the data gathered during your experiment. Then use that data to form a graph if possible. For example, here is a fictional chart about plant growth with varying water temperature.
Average Plant Height in cm
Tables are used to organize and display raw data.
Use a bar graph to compare quantities. For instance, you might use a bar graph to compare the heights daily or on a specific day. If you create your table in a spreadsheet program, it will create your bar graph for you.
A line graph could also be used to illustrate the plant growth. You could use one line for each plant. Usually you want to avoid having many lines on the same graph. Line graphs are useful for plotting many data points on the same graph.
Tables, charts, and graphs convey the information to the viewer easily without a lot of reading. This is very desireable on your display. You want your viewer to be able to comprehend what you have done quickly. Tables, graphs, and charts will help you to do that.
For examples of effective use of tables, charts, and graphs check out these completed experiments:
There are several software packages which will help you form graphs and charts. If you keep your data in a spreadsheet table such as Excel, it will automatically create charts and graphs for you. Be careful to include proper labels so that it is obvious what the graph is about.
