YOU CAN HAVE ADVENTURES

Students and Parents:

Looking ahead to the coming academic year, what should you expect from science coursework?  What's the point of taking science, anyway?  Where could studying Biology, Chemistry or Physics ultimately take you?

Back in 2016, I was the subject of a profile by local news station KSEE 24.   They had learned some things about my career as a science teacher, and they were intrigued by how I answered questions like that.  

It may seem corny, but the truth is that learning can be an intellectual adventure---a 'voyage of the mind'----and the results of that learning can lead to actual physical adventures!


HOW?

POWER POINT NOTES: CARBON, THE 'SHAPE OF LIFE'

Students:

You are now beginning your Final Unit of the year, on Organic Chemistry.  This is the branch of chemistry based on the element carbon.  This is not only essential for living things, but heavily-involved in many important concerns of modern life, including the use of fossil fuels and patterns of climate change, all topics in Volume 2 of your text.




To help students prepare for their Final, please find these Power Point Notes HERE, along with a PDF of the Study Guide based on those notes HERE.

Students should also have a copy of the Organic Compounds Guide (three-hole punched) as part of their materials in to be prepared to answer questions on their FINAL.

VIDEO: ACID-BASE EQUILIBRIUM

Students should have been given the worksheet based on this video prior to Spring Break.  In the video, Paul Andersen demonstrates the centrality of water to most acid-base chemistry, and explains how to calculate equilibrium constants for acids (Ka) and bases (Kb), and how to express those as pKa's or pKb's:

POWER POINT NOTES: ACIDS, BASES AND SALTS

Mr.Hatfield's Chemistry students should have completed their Notes on material related to pg. 146-171 (volume 2) of their textbook.   They can download a copy of the Power Point containing those Notes HERE:


Students received a Study Guide based upon this section of Notes on March 22.  This Study Guide will be completed before Spring Break.  After Spring Break, Mr. Hatfield's classes will complete their titration labs and have a Unit Test on equilibrium, solutions, acids, bases and salts.

POWER POINT NOTES: CHEMICAL KINETICS



Students, here are the Power Point Notes on Chemical Kinetics, which covers the concept of equilibrium and the rates of reaction.


The Study Guide has been made available in class since Friday, March 17th.  If you need to get another copy, you can download a PDF version of the Study Guide HERE.

UNIT 6 is now over, and all Unit 6 work is PAST DUE, and will NOT be accepted after Friday,  March 24th  


VIDEO: EQUILIBRIUM

In this video, Paul Anderson does a great job of providing a demonstration that suggests how chemical systems reach equilibrium.




Mr. Anderson also models how to equilibrium setups and solve for the value of the equilibrium constant, 'K'.  Students were given a worksheet based on this video in Friday's class, along with a set of problems in which they will practice setting up equilibrium expressions.

This is a short topic, and the notes on Chemical Kinetics should be finished within the same day as viewing the video.  Both items should be treated as homework, and completed as soon as possible.
