Wonders of Water Day 1

Thursday September 6^th

Based on this cartoon – What type of Bond is this “marriage” depicting?
An ionic bond since he is GIVING his electrons away.  Remember - I told you a way that I was taught to remember Ionic bonds is "I OWN it."  He GAVE her his electron so now she OWNS it!

What if instead the “boy” atom said “I do, Let’s share our valence electrons baby”  Which type of bond would it be referring to?
This would be a covalent bond.  Remember I told you that the prefix "co" means together, share or both.  In covalent bonds electrons are SHARED between two atoms.

After that we started into our discussion on water and its INCREDIBLY unique properties.  First I had you watch the following clip from the Waterboy.... WHY?!??!!  Because we are going to see that water does NOT suck and Gatoraide wouldn't have the effect it did if water wasn't the amazing molecule it IS!

We are in for some hands on stuff over the next couple days!!!
It may be hot in here - but we'll make the best of it :)

Then we started into notes about water.  Most classes got to the point of drawing out water molecules, seeing what makes it "polar" and then made some water molecules with pop-it beads.

Making water molecules out of pop-it beads

Note the "mickey mouse" shape of the water molecule.
This is due to the fact that water is held together by
POLAR Covalent bonds - so the electrons are shared
unevenly!!

4 perfect little water molecules!
Tomorrow we will see how they interact with each other
