Native
Renewables
To date, Native Renewables has helped install several off-grid
solar PV systems ranging from 750 W to 7 kW capacity, outreached
to hundreds of solar enthusiasts, and is addressing energy access
challenges by providing solar options to Native communities.

Super
Indian Comics
Creator/Writer/Artist Arigon Starr is a member of the Kickapoo
Tribe of Oklahoma and was raised in various cities across
the U.S. along with her Navy family. She’s been drawing
since she could hold a pencil. She’s produced cartoons,
drawings and artwork for many organizations including Native
Voices at the Autry, the Native Voice One Radio Service, rock
group Queen, the Walt Disney Company (for their retail outlets),
the National Park Service and other charitable groups around
the U.S. “Super Indian” has been a long time coming.

Static
Electricity
Has
your hair ever stood out from your head after pulling
off a wool cap? That’s the result of static electricity.
In their usual state, atoms are electrically neutral
because they contain an equal number of positive protons
and negative electrons. But when two materials rub together
(like your hair and your cap) some of the electrons
jump from one thing to the other, creating an electric
charge called static electricity.

PBS
Learning Media: Static Electricity: Snap, Crackle, Jump
In this video from the PBS science show ZOOM, a vinyl
record is rubbed on a wool scarf and then the record "magically"
lifts breakfast cereal right out of its bowl! After watching
the video, click on Support Materials to read an article
about static electricity and more about the experiment
shown in the video. "When rubbed with a wool scarf,
the surface of a vinyl record picks up extra electrons
from the scarf. If the charged record is placed over puffy
rice cereal, the electrically neutral cereal pieces become
polarized. Because opposite charges attract, the negatively
charged record lifts the positively charged ends of the
cereal pieces."

PhET:
Balloons and Static Electricity
This interactive experiment from the University of Colorado
at Boulder shows the effect of rubbing a balloon against
a wool sweater. You can do the experiment with one or
two balloons, add a wall to your experiment, and change
which of the charges are displayed. Be sure to move your
charged balloons around between the sweater and the wall,
and watch what happens.

Physics
Classroom: Static Electricity
The Physics Classroom (for beginning physics students
in high school or college) presents four comprehensive
static electricity lessons, starting with basic terminology,
and ending with lightning. "Perhaps the most known
and powerful display of electrostatics in nature is a
lightning storm. Lightning storms are inescapable from
humankind's attention. They are never invited, never planned
and never gone unnoticed. "

Science
Made Simple: Static Electricity
"Did you ever hear the saying
that opposites attract? Well, it's true. Two things with
opposite, or different charges (a positive and a negative)
will attract, or pull towards each other. Things with
the same charge (two positives or two negatives) will
repel, or push away from each other." Science Made
Simple is my static-electricity pick of the day because
of the depth of its coverage. Be sure to visit all three
pages by following the Read More link at the bottom. The
third page includes three static electricity experiments
you can do at home.

ScienceNetLinks:
Introducing Static Electricity
"The number of electrons in an atom — ranging
from one up to about 100 — matches the number of
charged particles, or protons, in the nucleus, and determines
how the atom will link to other atoms to form molecules."
Although written for teachers, ScienceNetLinks includes
plenty good info for students, including two activities:
Stuck-Up Balloon and Dancing Balloon.
