The chemistry students received the Learning Objectives for Unit 3 today. The unit covers Chemical Bonding and, boy, is it fun. We reviewed the work we did last Thursday on covalent bonding and extended that discussion into the use of Lewis structures. We also looked at the structure of water and briefly discussed the nature of polar covalent bonds and how that effects the characteristics of water. Surface tension is an interesting phenomenon. Just ask an insect.
The AP Biology students continued their review of the material that will be on their next exam which is on Wednesday of this week. The Cell Unit covers the structure and function of cellular components, mitosis and meiosis, cell respiration and photosynthesis. Man, that's a lot of info!
