UTEP/EPISD Border Air Quality Education BAQed.utep Grade 5 – Alternative Energies

1. UTEP/EPISD Border Air Quality Educationwww.BAQed.utep.eduGrade 5 – Alternative Energies Roxanne Ramos, Theresa Turner, Blanche Herrera, Amy Canales

2. Objectives • 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 TEKS Timeline 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

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

4. 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

5. Activity 2 – How Electricity is Made

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

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

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

10. Use wind to generate electricity

11. Use wind to generate electricity

12. Use wind to generate electricity Only generated about 5 milliamps.

13. Add gears to increase rotations

14. Add gears to increase rotations 15-20 milliamps of electricity generated

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

16. 10 minutes to find the best angle for the solar cell and the best 2 meter path to travel.

17. Solar cars raced against each other

18. How much electricity can the solar panel generate at different angles? 12:35 pm facing south Angle Milliamps 0 5 20 7 40 3 60 0 Kids Do Science -- Solar Car http://www.youtube.com/watch?v=OXcPFuAhvkk

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

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

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

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

23. 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

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