Replication of Watson and Crick DNA model, contains some of the original metal plates used for the bases.  http://www.sciencemuseum.org.uk/images/i030/10299555.aspx

 The spiral in a snail's shell is the same mathematically as the spiral in the Milky Way galaxy, and it's also the same mathematically as the spirals in our DNA.  It's the same ratio that you'll find in the very basic music that transcends cultures all over the world.  Joseph Gordon-Levitt

Biology Learning Goal:  The student will investigate the scientists that discovered the relationships between DNA and genes.  They will map, illustrate and perform laboratory investigations on the overall structure of the DNA model.  Make comparisons with RNA and recreate protein synthesis.

Investigation Lab:   Comparison of Bond Properties (www.catalystlearningcurricula.com)
Reflection Question Q & A

Experiment A: Geometric Crystal Structure
1. NaCl (salt)
2. NaCl (salt)
3. Refer to notes and text.
4. The greater the intermolecular attraction, the higher the melting point, vapor pressure
and boiling points.  
5.  Both shapes represent each molecules unique arrangement of atoms.  In NaCl, 
the ionic arrangement of salt molecules creates a structure similar to a 
six-sided dice, whereas the arrangement of carbon atoms creates a hexagonal shape. 
Experiment B: Hardness
1.  NaCl
2.  NaCl
3.  Cleavage patterns vary due to the bond types within the molecule. Regular cleavage patterns
are observed in molecules with high geometrical regularity, such as in ionic bonds.  
4.  N/A
5.  Hardness of molecules is related to atomic bonding.
Experiment C: Conductivity
1.  NaCl
2.  The molecules of the ionic solid are bonding with the partially positive and negative charges of distilled water.  
3.  The neutrally charged covalently bonded sugar molecules are not attracted to the polar solvent, and though some is dispersing into solution the majority remains a solid.
4.  When there are free electrons present in solution the electrical current is greater.  
Experiment D: Melting Point 
Experiment E:  Capillary Action
Experiment F:  Surface Tension
Experiment G:  Solvent Ability
