water molecule kitsWith the water molecule kits, figure out the following with your peers at your table:

  • What does the magnetic attraction between these plastic renditions of water molecules represent? Why are the water molecules only attracted to each other in certain ways, in certain orientations?
  • How would you depict (a) ice, (b) liquid water and (c) steam with this model kit?
  • Is the molecule with the gray sphere polar or non-polar?  Hydrophilic or hydrophobic?
  • What do the green and blue spheres represent?
  • How does this kit show us the relative strengths of covalent, ionic and hydrogen bonds?
