A pictograph could be used to represent the results of an experiment measuring the sun's altitude at noon over a three-month period. A pictograph is a chart that contains symbols representing data, such as quantities of an object. In the pictograph shown in Figure 5.11, each sun represents an altitude of 4 degrees. Pictographs are easy to read and can add a little fun to your data display. The data charted in Figure 5.5 was used to write a statement of the changes in altitude of the sun as observed in the sample project, as shown in Figure 5.12.
Photographs are another way to display data.
Have someone take a photograph of you performing the experiment, as in Figure 5.4, or take photos of the procedure setup to use as part of the project display. Use the format of the procedure shown in Figure 5.3 as a guideline to design your own project experiment. Figure 5.13 shows an explanation of the results of the sample experiment. This information, along with the other research, will be used to develop a project problem, hypothesis, and one or more experiments. First, if there is time, repeat the experiment to make sure everything is done properly.
