This week you will construct a 3-D model of DNA out of household junk. Make sure that you include the sugar-phosphate backbone and the nitrogen bases.
These beautiful works of art and science will hang in the room indefinitely, so be proud of what you do and take the time necessary to construct a nice model.
On the day this is due, you will be required to stand up in front of class and explain your model.

If you can find it, be sure to show your students "The Race for the Double Helix" starring Jeff Goldblum.
Just for fun: If you have access to a 3-D printer, print a DNA model.
