I received my graduate degree in organic chemistry from Kansas State University and have been teaching undergraduate chemistry courses for over 15 years. I strongly believe that you are never too old or young to learn and appreciate science and have had students ranging in ages from 5 to 65. Along with my college classes, I regularly teach science in K-12 classes and for special interest groups.

The usefulness of Enzymes as Biological Catalysts

Fall is creeping into my part of the world; harvest is in full swing and my thoughts are turning now to large dinners with ham, turkey and all the fixings. Of course, one of the things I am most thankful for after such a meal is catalysts.

The term catalyst is commonly used as an expression to identify a person or moment that started an event. In my world, it is a substance that helps speeds things up without being used up. Continue reading

Chemists and Parents compared, Kinetically speaking

Are we there yet?

Are we there yet? Are we there yet? Are we there yet? Are we there yet?...

Have you ever uttered or heard the phrase: Are we there yet? or How much longer?  Does this prompt flashbacks of your last family vacation!?  We are constantly interested in time, and how fast things happen. Chemists are no different, we merely change the phrasing to: Is it done yet, and how much longer? Continue reading

Can you be Electrocuted while showering during an Electric Storm?

Lightning on the Columbia RiverIt is a known fact that water and electricity should not be used at the same time but have you ever wondered why? Were you ever told that you could be electrocuted while showering or bathing, during an electric storm? Can an electric current really flow through water? Continue reading

Phase Changes with the most amazing substance ever!

Frost
There is one substance today that still has the power to amaze and entertain me as it did as a child. I never lose a chance to sing its praises and or to expound on its powerful chemical characteristics to all my students, young and old alike. Continue reading

The world of Equilibrium

Screen Grab of interactive anim - Le Chatlier's principle from Physical Chemistry Book

Chemistry would be a whole lot simpler if all the reactions would just make their expected products (or even some by-products) and then be done. Reactants and products have a mind of their own though and are influenced by temperature, concentration, some even by the weather (pressure)! Worse, some products can’t seem to make up their mind and turn back into reactants. Continue reading

Thermodynamics Module - Physical Chemistry
Thermodynamics module
Chapters 1 to 6 of Physical Chemistry - Laidler, Meiser, Sanctuary


Includes multimedia that opens on relevant pages and allows the student to visualize many of the concepts by varying parameters and plotting different graphs. Things students often have difficulty with, such as isothermal, isobaric, isochoric and adiabatic process, are clearly visualized.

Physical Chemistry - Laidler, Meiser, Sanctuary
Physical Chemistry textbook
by Laidler, Meiser, Sanctuary


This popular Physical Chemistry text book is now available in electronic format. We have preserved much of the material of the former hard copy editions, making changes to improve understanding of the concepts in addition to including some of the recent discoveries in physical chemistry. Many chapters have new sections and the coverage of several chapters has been greatly expanded.
