This is a reminder that the test on basic chemistry and water chemistry is this Friday for my general biology classes (BLKS 2,4,7)  This is the material in your text:  Ch. 6.1 and 6.2.

Review your notes, your lab journal notes, the pH lab we did, and your vocabulary.  We have gone over many of the vocabulary terms and concepts multiple times so you should have them in many places, explained in many forms.

Practice drawing atoms, atoms like:  C, H, O, and N.  Review the chemical symbols of the common elements.

Practice drawing the water molecule, and then 3 water molecules together showing the proper polarity (the oxygen end charged neg. and the hydrogen ends charged +) 

Review the concept of ‘density’ … and how water’s ability to hold heat affects our weather.

Study so that you can earn a good grade on this first test.  :-)
