Energy Conservation

  1. 1. Energy Conservation Project: Warm-up Activity Paper Consumption in the Annette Island School District
  2. 2. The Question: How much paper could we, as teachers, help our students to conserve by providing previously used paper for the warm-up activity?
  3. 3. Why Paper Conservation? <ul><li>Each person in the United States uses approximately 750 pounds of paper each year . </li></ul><ul><li>This equals approximately 187 billion pounds per year .” </li></ul><ul><li>“ Most of the world’s paper supply , about 71 percent, is made from forest-harvested timber , from regions with ecologically valuable , biologically diverse habitat.” </li></ul>
  4. 4. Methodology: <ul><li>How much paper does each of my two Spanish classes use, on average, each week for the warm-up assignment? </li></ul><ul><li>How many secondary teachers in the AISD give warm-up assignments? </li></ul><ul><li>What is the average number of classes each student has? </li></ul><ul><li>How many secondary students are there in the AISD </li></ul>
  5. 5. Data Collection: <ul><li>Data collected on paper use for warm-up activity over a two week time period and averaged to find a more accurate count. </li></ul><ul><li>Number of secondary students in the school district (as related by the District Secretary). </li></ul><ul><li>Number of secondary teachers (I counted). </li></ul><ul><li>Percentage of secondary teachers who assign warm-up activities as recorded through the use of a survey. </li></ul>
  6. 6. Data Collection Errors <ul><li>The P.S.A.T. testing interrupted classes making numbers lower than usual one day. </li></ul><ul><li>Students had appointments, went on family vacations, and were generally absent more often than normal. (But then what is “normal.” Students not coming to class is typical.) </li></ul>
  7. 7. Raw Data as Collected in my Classroom 2 Week 1 Week 36 16   32 18 Sheets of Used   Total Paper   Sheets of Used   Total Paper 6 3     4.5 2 7.5 3     3 4 7 2     6.5 4 9 4     9 4 6.5 4   9 4 Spanish I Spanish II     Spanish I Spanish II
  8. 8. Information Derived from Data <ul><li>Weekly Paper Average Spanish I = week 1 + week 2 / 2= 34 sheets of paper </li></ul><ul><li>Weekly Paper Average Spanish II = week 1+ week 2 / 2 = 17 sheets of paper </li></ul><ul><li>Average Weekly Paper Consumption by 1 Student in Warm-up= Spanish I Average + Spanish II Average/ total # of students in the two classes = 3.1875 sheets of paper </li></ul>
  9. 9. Additional Data Collected <ul><li>Number of Full-Time Secondary Teachers in AISD = 14 </li></ul><ul><li>Number of Teachers who Assign Warm-up Activities = 8 </li></ul><ul><li>Number of Secondary Students in AISD = 123 </li></ul><ul><li>Average Number of Classes Taken by Students Each Day = 7 </li></ul>
  10. 10. Information Derived from Additional Collected Data: <ul><li>Percentage of Teachers who Give Warm-up Assignments : Number of teachers who give warm-up Assignments/ Total Number of Teachers = 57.1429% </li></ul><ul><li>Sheets of Paper Used by Student Body in 1 week= (% of Teachers that Assign Warm-up Activities)(# of Students) (Average # of Pieces of Paper per Student per Week)(# of Class Periods )= 1568 Pieces of Paper </li></ul>
  11. 11. How Much Paper Could the AISD Save? <ul><li>If the entire district used previously used paper for the warm-up assignment we would save: </li></ul>Sheets of Paper 59,584 One Year 29,792 One Semester 14,896 One Quarter 1,568 One Week
  12. 12. ASSUMPTIONS <ul><li>Students will use previous used paper rather than new paper if it is provided. </li></ul><ul><li>Teachers assign warm-up’s at the same rate as I do. </li></ul><ul><li>Spanish students are representative of the typical AISD student. </li></ul>
  13. 13. Future Steps <ul><li>I will provide previously used paper to my Spanish students for the daily warm-up and other assignments. </li></ul><ul><li>I will encourage others to provide previously used paper to their students. </li></ul><ul><li>I will print un-important documents onto the blank side of previously used paper . </li></ul>
  14. 14. Paper Saving Technologies <ul><li>In the next few years Xerox and the Palo Alto Research Institute will be selling printers that use disappearing ink. </li></ul><ul><li>25% of documents that get printed get recycled the same day. </li></ul><ul><li>The ink will disappear 18-24 hours after printed and the paper can be used multiple times. </li></ul><ul><li>I plan on following this technology and employing it in my classroom A.S.A.P. </li></ul>
