Wonders of water Day 2

Friday September 7^th

Draw and label a water molecule 

What type of bond holds together this water molecule?

Because of this there are “partial” charges associated with it.  Which end acts +, which acts -? (Label those)

Using the models in your tubs – make 5 water molecules then place how you think 1 would bond with 4 others.

 What type of bond holds two water molecules together?

Your pop-it bead water molecules.  See how
the Hydrogens bond with oxygen and vice
versa - you will never see a Hydrogen bonded
with hydrogen of another water molecule.

Remember EACH of these would then be bonded to four Water
molecules which leads to a very complex crystal form

We then took one slide of notes on Cohesion and surface tension then got to see that in action!  Check the next blog post for pics on this activity.  (Remember - get notes off Edline if you are absent)
