What they say is very true – teachers can really learn a lot
from the students they are teaching!
Recently, Plano Solar Advocates volunteers had the wonderful
experience of engaging in lessons, discussions, and Q&A with elementary
students in 14 different class sessions (a total of 215 students) while helping
them assemble demonstration solar powered cars.
And when the sun was shining, those cars went really fast!
In collaboration with the Texas Solar Energy Society, the
North Texas Renewable Energy Group local chapter, and the Live Green in Plano
volunteer program, Plano Solar Advocates volunteers went on a mission the last
5 weeks of the school year to share information about solar energy with 3rd,
4th, and 5th graders at area elementary schools.
The Solar Car Class
We started each class by talking about the huge amount of
energy that reaches the earth from the sun. We described the four types of
solar energy we can use – passive, thermal, concentrating, and photovoltaic
(PV). We showed photos of PV installations around the area, and showed photos
and websites about experimental solar airplanes, boats, and cars.
We then discussed the difference between non-renewable and
renewable sources of energy. We discussed how conventional cars are powered by
burning gasoline, and we described how an electric car powered by solar panels
would work.
The students then worked together in small teams to assemble
the solar car kits. Outside, they then
put the cars through their paces and even had a few races. The students made
observations and conclusions about sun and shade and how switching the
electrical connections changed the direction of the car.
Once we were back in the classroom, the students practiced
one of the three “R’s” of sustainability (Reduce, Reuse, Recycle) by
disassembling the cars so that they could be “reused” at the next solar car
class session. We had a little more time
for Q&A, and then encouraged the students to continue to learn and
strengthen their knowledge in math and science so that they could become future
scientists, researchers, engineers, and business people to capitalize on the untapped
natural energy resource of the sun. We
closed the class by having the students watch a short video called – “Solar
Energy in Texas – Don’t you wonder?”
Good Timing
Regarding our future migration to more renewable sources of energy
and the pioneering spirit and creative thinking we will need to accomplish
this, we were very fortunate that the Solar Impulse solar airplane (
www.solarimpulse.com) was arriving and
staying at the DFW airport during for the latter part of May. Many of the
students were able to go see the plane and learn more in person!
The Experience, Next Steps, and More Info
We had a great time speaking and teaching these classes, and
we received similar feedback from all the other volunteers who were able to
participate. Most importantly, the students were engaged, excited, asked very good
questions, and will be the future ambassadors (and consumers) of solar
energy. We received many various thank you letters and even songs
composed about solar energy to be sung to current tunes that older folks (like
us) might not recognize….
We hope to be able to reach more students next year, so be
ready to help answer the call to lead or assist the solar powered car lessons
next spring. It is a great experience to
encourage and motivate our next generation to learn about and use renewable
energy. It will create fond memories for both you and the students that will be
remembered for a long time.
