Orchard Students Turn RAFT Materials into Safer Wind Turbines for Birds

Ten third graders and twelve fourth graders in Kathleen Gould’s class at Orchard School District know to turn to RAFT when making creative design solutions! They’ve been on a 17-day Design Challenge journey studying how wind turbines kill hundreds of thousands of birds each year in North America—making turbines the most menacing form of green energy!
Using cardboard tubes, paper pinwheel blades, clay, tape, stickers, cotton balls, bubble wrap, and other RAFT materials, student teams were able to think about and design clever models of wind turbines that might be safer for birds to fly around or nest upon!
It started when representatives from the WildLIFE Associates brought into the class rehabilitated falcons, owls, eagles, and other birds damaged by wind turbines. “We learned about Luna the owl, who is now blind in one eye, and Liberty, the bald eagle, who broke its wing from flying into a turbine,” says Gould. Seeing these beautiful wild creatures up close helped the students to empathize with the real-world problem of how to protect birds flying around wind turbines.
“The kids really loved this Design Challenge!” adds Gould. “They researched the history of windmills as sources of energy. They learned about food chains with a fun card game. They studied different bird habitats within California and where wind turbines are located in the state. They had to think about how we impact bird lives.”
Once the students defined the problem, they did the research. They looked at maps of flight patterns and at human habitats that encroach on bird habitats and flight paths. They researched how electromagnetic energy is produced from wind power with hand-crank generators and then compared this to wind turbines. And they made and remade models!
“They loved designing models! They were super excited to experiment with the RAFT materials, learning what did and did not work by testing the strength and weaknesses of different pinwheel blade designs. They had to improve their designs over and over until they created what they thought was the perfect solution for a safer wind turbine!”
Student teams presented their final designs in front of a captive audience of parents and teachers. Several designs included cotton balls attached to a turbine pole and base—“the cotton balls are soft and they won’t hurt the birds that much if they bump into them.”

Another team made a huge net surrounding the turbine to distract the birds from the turbine blades, and said they’d recommend placing the turbines far away from where birds like to live. Other suggestions included coloring the turbines bright colors and putting flashing lights on them so the birds can see them better.

“This was such a highly successful Design Challenge!” comments Gould. “RAFT materials really helped the students understand the problem by using hands-on modeling to find new ways to protect the birds while still living with green energy technology!”

¡Olé! Celebrate Cinco de Mayo

¡Olémis amigos! Holy Guacamole! It’s once again time to celebrate Cinco De Mayo—the 5th of May! Instead of all the controversy around Mexico in the past year, this may be an excellent opportunity to educate your students and allow them to ask questions about what they hear on the news. Cinco de Mayo is not Mexico’s Independence Day from Spain (which is September 16th)! “¡Ay, caramba!”as Bart Simpson would say….

This is “la verdad” (the truth): when the French invaded Mexico in 1862, Mexican General Ignacio Zaragoza’s force of 4,000 soldiers defeated 8,000 French soldiers in the Battle of Puebla on May 5th. The Mexicans’ courage inspired Mexican Americans (Chicanos) to celebrate the victory even though the French occupation continued four more years. Later in the 1960’s and 70’s, Chicanos involved in the civil rights movement associated Cinco de Mayo with their quest for respect in the U.S. They identified with the Native Mexican and Mestizo (people of mixed Native Mexican and European de…

Why I Chose a Career in Education

There are many moments where I am reminded why I chose a career in education. These moments arise when I am engaged in conversation with other teachers, conducting professional development workshops, developing new lessons, or simply reading about changes and latest developments in the field. Education is a dynamic field, and it has provided me with many opportunities to positively impact the lives of young learners as well as provide inspiration and support to new teachers. One such occasion occurred in mid-April when I was invited by Dr. Rosalinda Quintanar to conduct a presentation to students in a class entitled Meeting the Needs of Second-Language Learners (EDTE 162), a course within San Jose State University’s Teacher Education Department and a credential requirement. The class consisted of approximately 30 credential candidates, and its primary focus is applying theory and practical classroom techniques for providing equitable access to content for English language learners.

National Arbor Day is Coming… Hug A Tree!

“The cultivation of flowers and trees is the cultivation of the good, the beautiful and the ennobling in man, and for one, I wish to see this culture become universal.”
Those words, from J. Sterling Morton, the founder of Arbor Day, got me thinking about how caring for trees and respecting all living things greatly impact future generations. National Arbor Day (held this year on April 27th) is an annual observance celebrating the role of trees in our lives and promoting tree planting and care. This holiday was first observed in 1872, in Nebraska, but tree planting festivals are as old as civilization. Trees have appeared throughout history as the symbol of life and hope. As teachers, we can encourage students to appreciate trees, nature, and all living things for future generations to enjoy! Here are a few STEAM (Science, Technology, Engineering, Arts, and Math) ideas to help you spread agricultural information and enthusiasm for trees on Arbor Day with your students: SCIENCE: Explore t…
