Teaching students how to report on the weather also opens up lessons for graphs. Students must decide what graph is best to organize their data to present to the class.
Why teach students about graphs in Science class and not Math class?
Graphs should be taught in math, science and other classes when there is a need to illustrate data. Students are taught about graphs in math but often are unsure of how to apply this knowledge outside the classroom. By having students create graphs in a variety of situations, students will gain a deeper understanding of the concept. If the student has a deeper understanding they are more likely to remember this information for future applications.
Questions to Ask
Would you use a pie graph to record your temperature data? Why or Why not?
Am I allowed to use a pictograph in grade 4? Why or Why not?
Should I be allowed to use a computer program to create a graph? Why or Why not?
Why do we use graphs, is it not easier to just present the data without graphs?
Can two graphs illustrate the same information? Why or Why not?
Types of Graphs
Bar Graph: Its purpose is to show relationship between groups. Students may use a bar graph to illustrate sunny and cloudy days.
Line Graph: Its purpose is to show how data changes based on one criterion. Students may use the line graph to plot the temperatures weekly, monthly, and annually.
Pie (Circle) Graph: Its purpose is to show how a part relates to the whole. Students may use a pie graph to illustrate the different winds based on the Beaufort Scale. The pie graph will quickly show the main type of wind for a specific location.
Pictograph: Its purpose is to show relationship between groups. Often the picture is symbolic of what is being measured. Students may use snowflakes and rain pictures to record precipitation levels.
Students can create a graph via hand or a computer program. Students should practice creating graphs by hand and by using a computer program.
