- What is the “Valley of Death”? What other fields have a problem translating research into practice, and how do they attempt to speed the translation of research into practice?
- Ask the class to look at the predictions for yesterday’s weather from 7, 5, 3 and 1 day ago. Do the forecasts grow more accurate? Which aspect improves the most: temperature, precipitation, wind speed or wind direction?
- Reread the forecasters “plea” in the article and ask the class to write 150 words on these topics: Why would a forecaster write this kind of plea? Do you think it would be helpful? What else could a forecaster say to persuade more people to evacuate low-lying areas?
- Research question: Assign a short paper on the tornado outbreak of Apr. 25-28, 2011. Papers can cover causes, damages/deaths, and lessons learned.
