Shocking News from Challenge
Today we learned about how lightning is formed. Lightning is formed by water particles
getting hit by other particles and breaking the electrons of the particle
off. The electron sinks to the bottom of
the cloud. Electrons have a negative
charge that is attracted to a positive charge which is in the ground. The negative charge forks and looks for the
path of least resistance. When it finds
its path it releases the energy through the path, but not at the same
time. When it is finding its path, positive electricity comes out of a path of little resistance An example of this is a
tree or a metal pole. We call these
lines of positive charges streamers.
We created positive and negative electrical charges by using balloons and rubbing them against our hair. It separated the electrons and the protons like particles of water in the clouds striking each other. The “streamers” (a.k.a the hair) reached up to meet the negative charge from the “thunder cloud” (a.k.a the balloon).
Can you see the positively charged “streamers” reaching up to meet the negative charge from the “thunder cloud”?
The attraction of the negative and positive charges also
made the balloons stick to our heads and to the chalk board. I had a lot of fun
while learning about lightning and doing the balloon lab.
