1. UTEP/EPISD Border Air Quality Education www.BAQed.utep.edu Grade 5 – Alternative Energies www.BAQed.utep.edu Roxanne Ramos, Theresa Turner, Blanche Herrera, Amy Canales

2. Objectives TEKSTimeline 5.7(C) identify alternative energy resources such as wind, solar, hydroelectric, geothermal, and biofuels; Wind – 2-3 class periods Solar – 1 class period Biofuel – 1 class period Action Plan – 1 class period Introduce activities that allow students to experience generating electricity from alternative energy sources Develop a plan of action to reduce energy use at school in order to improve our border air quality

3. Materials Wind YouTube story of Kamkwamba or the book, The Boy Who Harnessed the Wind by William Kamkwamba and Bryan Mealer Hand crank generator Windmill kit from Science Geek Box fan Small motor Multimeter Solar Solar car racer Meter sticks Stopwatch Protractor Multimeter Light meter (from ScanTEK kit) Biofuel Metal coffee can Small tin can Metal skewer Binder clip Matches Thermometer Corn chip Corn oil Fondue fuel or sterno

4. Activity 1 The Boy Who Harnessed the Wind by William Kamkwamba and Bryan Mealer Moving Windmills (6:07) http://youtu.be/arD374MFk4w http://youtu.be/arD374MFk4w

5. Activity 2 How Electricity is Made Electricity is the flow of electrons Michael Faraday Magnet moving in a coil of wire causes electrons to line up and generate an electrical current

6. Activity 2 – How Electricity is Made

7. Activity 3 Energy from the Wind How to assemble wind lift video: http://teachergeek.com/products/teachergeek -wind-lift http://teachergeek.com/products/teachergeek -wind-lift Printed instruction guide: http://www.teachergeek.org/wind_lift.pdf

8. How many marbles can the wind lift pick up?

10. The winner: 20 marbles in 5.5 sec at fan speed 1

11. Use wind to generate electricity

13. Only generated about 5 milliamps.

14. Add gears to increase rotations

15. 15-20 milliamps of electricity generated

16. Activity 4 Solar Cells Capture the Sun's Energy

17. 10 minutes to find the best angle for the solar cell and the best 2 meter path to travel.

18. Solar cars raced against each other

19. How much electricity can the solar panel generate at different angles? 12:35 pm facing south Angle Milliamps 05 207 403 600 Kids Do Science -- Solar Car http://www.youtube.com/watch? v=OXcPFuAhvkk

20. Activity 5 The Basics of Biofuels: Corn Power Corn is a natural resource that is renewable Uses of corn

21. Ethanol from Corn video http://www.youtube.com/watch?v=xsROhOMIYdU

22. Biomass Pollution Demonstration Peanut Power (because of allergies, we don’t use peanuts, we use corn chips. http://www.energyquest.ca.gov/projects/peanut.htmll http://www.energyquest.ca.gov/projects/peanut.html

23. Biomass Pollution Demonstration Corn Chip Solid Fast burn Lots of smoke Burnt remains Corn Oil Liquid Slower burn Smoke No residue (except wick) Ethanol Liquid Long burn No smoke No residue

24. Activity 6 Reducing Energy Use at Our School Learning about energy use by the district and by campus Making energy reduction posters Sending energy announcements across the school’s PA system

25. Check your district’s facilities website. Most districts have the energy consumption charted by school. For EPISD, see the next slides How to find energy usage reports by campus

26. Click here to get to the Energy Management page Log on to my episd main page

27. District Energy Home Page Select the “Energy Mgmt.” tab

28. Click on “Energy Management Reports” to see the energy reports

29. Most recent month Last 4 years Individual years (including current year)

30. February 2014 Energy Use

31. August 2013 Energy Use

32. Electricity Usage Over Four Years

34. Energy Saving Posters Students brainstorm ideas before using poster board

35. Student Samples
