How do we represent data? One way we represent data is in a pie chart. What are other ways that we represent data? (write student ideas here)
Why do we represent data in these ways? Why do scientists represent data in these ways? For example, why would a pie chart be better than a table? What about other ways (graphs, images, charts, tables, etc.) Consider what different information can be displayed in different representations.
In this activity we are making a graph of data about arctic sea ice. Why? What will a graph allow us to see that these images don’t?
Graph Title Vertical Axis Label Horizontal Axis Vertical Axis Units Units Horizontal Axis Label
What do these graphs tell us? Average Rainfall in a Desert in Egypt What does the horizontal axis tell us? What does the vertical axis tell us? What do the graphs tell us about rainfall overall? Average Rainfall in a Coniferous Forest in Canada Turn and Talk: With a partner, think of a 3-5 sentence description of the information in these graphs. Be prepared to share your explanation with the class.
Option 1: Go to http://nsidc.org/data/seaice_index/archives/image_select.htmlto find data about artic sea ice extent (Select Hemisphere Northern, Start Year 1979, Start Month September, and Image Sea Ice Extent, and check the “Fixed Month Animations” Box)
Option 2: Use the following slides to complete the table on Page 1 of your worksheet.
