1. Global Warming Mini-Unit By Kristen Cacciatore ESCI (ECOS 597) November 15, 2003

2. Goals Introduce global warming and climate change Improve graphing, computer, and statistical analysis skills Reinforce the distinction between data and resulting inferences and predictions Develop context for our studies in the field at Mother Brook

3. Overview DAY 1 – Introduction of global warming via interactive animation on EPA’s Global Warming for Kids website DAY 2 – Statistical analysis of BHO weather data and discussion DAY 3 – Graphing of atmospheric CO2 levels DAY 4 – Presentation of graphs and summary discussion

4. Today’s Presentation Viewing of the EPA Website animation at http://www.epa.gov/globalwarming/kids/anim ations.html Discussion of BHO temperature data from 1891-1910 and 1981-2001 Presentation of atmospheric CO 2 data Feedback and questions from you

5. BHO temperature data Students will: Each analyze the mean, median, and range for one month’s mean temperature for either 1891-1910 or 1981-2001. Then compare their results with the same month for the other time period Answer questions and draw inferences from the comparison The mean change for all months is 2.1 F

6. Atmospheric CO2 data graphing Students will: Graph CO 2 data from 1870 to 2000 by hand Extrapolate future CO2 levels from their graph Input and graph data on Excel Present graphs and predictions to the class

8. Assessment Online quiz at EPA site Accuracy of data analysis Homework questions on BHO data analysis and conclusions Graph presentation assessed by rubric
