FYI

Just a FYI....Yeast smells disgusting after being microwaved!!!

Breaking Down Sugar

I put yeast, water, and brown sugar in this container and let it sit for about an hour
I could still see the sugar in it



In this container I put yeast, water, and brown sugar in it, but i microwaved it for 40 sec
There was less sugar in this container than the first one




For this container I only put water and brown sugar in it and I microwaved it for 40 sec as well
This was the one with absolutely no sugar in it




In this container I put water and brown sugar in it, but i boiled this one
This container also had no sugar left in it




Here is an overview of the experiment!!!



Test One: Number Three

Tell me what you think about...im starting to think that the dolls are a little bit creepy...haha!

Test One: Number Three

This is the " cotton candy model "
This is the most current model that we still have today
Inside the nucleus we have protons and nuetrons ( protons white balls and nuetrons green balls )
The elctrons are also in orbit ( dolls are electrons is orbit )

This is Rutherford's model of the atom....
He knew about electrons, but he didn't know that they orbited around the atom ( in this case the dolls are the electrons )
He also discovered the nucleus, but his model was not complete yet because he had no neutrons in it ( the little white balls is the nucleus )

This is Bohr's model of the atom
He was a student of Rutherford's and proved him wrong
He figured out that the electrons aren't just in some random place, but they actually orbit around the nucleus ( the dolls are walking around the nucleus as you can see in a single file )




I was trying to be creative....so here is my attempt!  haha

Video

Gray and I created a history for atoms video...it is really interesting so i hope you will watch it!!!
Thanks
