Grade 5 – Alternative Energies
Roxanne Ramos, Theresa Turner, Blanche Herrera, Amy Canales
Objectives
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
• 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
Activity 1The Boy Who Harnessed the Wind by
William Kamkwamba and Bryan MealerMoving Windmills (6:07)

Activity 2How 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
Activity 2 – How Electricity is Made
Activity 3

How many marbles can the wind lift pick up?
The winner: 20 marbles in 5.5 sec at fan speed 1

15-20 milliamps of electricity generated
Activity 4Solar Cells Capture the Sun's Energy
10 minutes to find the best angle for the solar cell and the best 2 meter path to travel.
Solar cars raced against each other
How much electricity can the solar panel generate at different angles?

Activity 5The Basics of Biofuels: Corn Power•Corn is a natural resource that is
renewable•Uses of corn
Ethanol from Corn video http://www.youtube.com/watch?v=xsROhOMIYdU
Biomass Pollution Demonstration•Peanut Power (because of allergies, we don’t use peanuts, we use corn
chips.

Biomass Pollution DemonstrationCorn 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
Activity 6Reducing 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
•Check your district’s facilities website. Most districts have the energy consumption charted by school.
•For EPISD, see the next slides
