Vortex/Vortices

 Ahhh, homeschooling and 3rd grade science.  This is where the morning took us...


Today we looked at VORTICES and did an experiment with two Pepsi bottles and a vortice junction.
Question:  What is a vortex?
Baron:  A vortex is the spinning movement that makes a tornado or whirlpool in liquid, gases, and air.  It spins and sucks everything towards its center.

Question:  Give me examples of vortices.
Baron:  Water creates a whirlpool.

Baron:  The solar system exists in a vortex.
Question:  Please expand on that thought.
Baron:  That's hard to expand on.
Please try.
Baron:  Planets spinning around the sun in a helical motion.
Question:  How do we know that the galaxy is a vortex?
Baron:  Actually, the outer space force is pulling and it keeps everything in place and the sun is pulling and gravity keeps the planets in position in the vortex.
Question:  Can you think of examples of vortices?
Baron: Hurricanes, storms, tornadoes, and Jupiter's storm.
Very good.

We watched an interesting video about the helical vs heliocentric movement in our galaxy.  A must-see in HD!

A very straight forward explanation of the helical orbit theory.
