Earthquake Data

Earthquake Focal Depth vs Surface Wave Magnitude







*Click the Year (All) square at the top of the visualization.

Answer the following questions.

1. What data does the visualization provide?

2. How do the background and visual elements of he display help you interpret the data?

3. What happens when you click of the All button for year? Why do you think this happens?

4. What is the range of the years the visualization covers?

5. Select the year 2008 and hover over one of the circles in the United States. What data are you provided with?

6. Find the mean of the focal depth for the circles in the United States. Does this data accurately represent the average depth of earthquakes in the United States? Why or why not?

7. Slide the Focal Depth slider until there is only one circle. What was the depth of this earthquake? Where is it located (longitude/latitude)? What country is this near?

8. Return the Focal Depth slider back to the minimum and maximum values. Now slide the Surface-Wave Magnitude (Ms) slider until the minimum value is 6.37. Where are all of the earthquakes located? What does this tell you about this region?

9. Return this slider to the minimum 3.5. Is there a month that has more earthquakes than another? Less than another? Do you think there is a reason for this?

10. Open the website http://www.maps.com/ref_map.aspx?pid=12871 in a new window. Draw and label the different tectonic plates on your world map.
a. Place the earthquakes from year 2011 on your map in red.
b. Place the earthquakes from year 2008 on your map in green.
c. Place the earthquakes from year 2006 on your map in blue.
d. Place the earthquakes from year 1584 on your map in orange.
What do you notice? Why do you think this is?

11. Select a region on the map that you can get earthquake data on for 10 consecutive years. Graph the focal depth and the surface-wave magnitude for this region. What do you notice? What type of graph did you choose to create? Why?

12. Write and answer three mathematical questions that can be answered using the above visualization or the graph you created.

13. Write and answer three science questions that can be answered using the above visualization or the graph you created.

14. Write and answer three geography questions that can be answered using the above visualization or the graph you created.

History of the World Cup
(Author of Visualization: Ross Perez, published on Tableau)








1. What do the circles on the map represent?

2. What do the colors on the map represent?

3. What do the flags on the histogram represent?

4. Identify the type of graph represented by the flags.

5. Find Brazil, United States, Mexico, Wales, and 2 of your choice. Convert the winning percentage and tie percentage to decimals and fractions in reduced form.

6. Place the countries on a number line labeling with the decimal and fraction.

7. Write an equation for each of the countries in #5 that shows how to find the winning percentage and the tie percentage. Clearly show your process.

8. Select the different continents using the select continent pull down menu. Find the mean, median, mode, and range of the number of games played for all the different countries included within each continent.

9. From your data, determine which measure of central tendency is best to use in creating a graph and justify your choice?

10. Create a graph to represent your data from #9.

11. What does the red line on the histogram represent?

12. What were the big ideas (objectives, essential learnings, performance expectations, etc.) in this activity?

13. How did you feel about this activity?
