Dear Grizzlies,  welcome to my online Chemistry class!                                                                    

Chemistry is in every aspect of our lives. From the food we eat to the shampoo we use, to the processes inside of your cells that allow the food you just ate to become so small that they can now move in and out of your cells' membranes. If you like cooking or baking, you are already a Chemist!       
Have you ever observed a  rusted piece of metal? That metal underwent a chemical process called oxidation. (Links to an external site.) What causes oxidation? (click the blue word to watch a cute video).
Hmmm.... What about curly hair? You guessed it! Chemistry again! The protein in your hair contains sulfur atoms. Sulfur atoms pair up to form disulphide bonds. It is the distance between these sulphur atoms that makes hair curl. The further apart the atoms are, the curlier the hair is (you read it right!).  
My hair is wavy.  Hmm... Why do you think that is? What about your hair?

The following units represent the material we will attempt to cover during the year. I will present these subject matter using different methods including lectures, video conferences and several websites. As the year progresses, I will update each unit by adding content to it.  
it is extremely important that you follow up and are on top of each assignment. Chemistry builds up on previous knowledge and falling behind in your work load will make it difficult for you to understand future lectures and assignments. 

I am looking forward this new academic year despite its many challenges!
