Goals l.jpg
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


Overview l.jpg
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


Today s presentation l.jpg
Today’s Presentation

  • Viewing of the EPA Website animation at

    http://www.epa.gov/globalwarming/kids/animations.html

  • Discussion of BHO temperature data from 1891-1910 and 1981-2001

  • Presentation of atmospheric CO2 data

  • Feedback and questions from you


Bho temperature data l.jpg
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


Atmospheric co2 data graphing l.jpg
Atmospheric CO2 data graphing

Students will:

  • Graph CO2 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


Assessment l.jpg
Assessment

  • Online quiz at EPA site

  • Accuracy of data analysis

  • Homework questions on BHO data analysis and conclusions

  • Graph presentation assessed by rubric
