Welcome Back

 I hope you had a great Thanksgiving.  

Period 1: I might be late to the Zoom meeting.  Please log into Google Classroom for instructions.  

The Molecules of Cells.

 Read through the notes and memorize the new vocabulary words.  Doing so will help with the understanding of the chapter.  The fill in the blank pages that correspond to the notes have been posted in Google classroom.  Please attempt the questions before class tomorrow.

Writing a Lab Report

 The first fifteen minutes of class will be spent explaining how to write a lab report.  

We will continue to discuss the versatility of the hydrocarbon leading into the introduction of the macromolecules.

The 4 Macromolecules"

1) Carbohydrates

2) Protein

3) Lipids

4) Nucleic Acid

Chapter 3: The Molecules of Cells

Hydrocarbons 

 

Unlike compounds formed from other elements, carbon compound are far more numerous and varied.  There are several million carbon compounds known and several hundred thousands are synthesized each year. 

Straight chain hydrocarbons: 

Branched Hydrocarbons

Ring structure

The most common elements found with carbon are hydrogen, oxygen, nitrogen, sulfur, phosphorus, and the halogens.

Water Properties Lab

 You will fill out the answers based on the demonstration of the lab.  No formal lab write up is required for this lab.  

The class will end with the PowerPoint presentation.

Irregularity of the density of water. The highest density of water occurs when the molecules are packed tightly together.  The crystal arrangement of ice has a lot of space incorporated in it. There are fewer molecules of water per volume in ice, than there are in water. 

Cohesion vs Adhesion.

Happy Veterans Day

Have a godd break. We will continue on Thursday. The vocabulary link is still broken. The 4 words from Tuesday's class are: ionic bond, covalent bond, Polar molecule, non-polar molecule
