As previously mentioned, we are having our first Unit Test in Biology on Wednesday (today). Students are welcome to come to my room during lunch and/or after school if they need extra time for the non-SCANTRON portions of the test.
Students who are unable to come at lunch or after school who wish to have additional time to work on the test should bring a note from their parent or guardian as justification.
We start our next Unit (Biological Molecules!) tomorrow, in class! Our first topic is the properties of water, as discussed in pg. 40-43 of the textbook:
Water is often described as a 'polar' molecule. Can you see why from this picture? If you can't, you need to re-read section 2.1 of the textbook, where it discusses polar covalent bonds. You'll need this knowledge to understand some of the properties of water, such as cohesion.
By the way, in case you haven't noticed, there is a link on the side of this blog that takes you to a web site to go with our textbook, 'The Dragonfly Book', by Ken Miller and Joseph Levine.
