Before the lesson

The Lesson:

Discussion

We start out the class with a discussion of what students already know/understand about the topics listed in the Overview.

Discussion goals

The purpose of this discussion is to show that the order in a sequence is very important. We execute tasks every single day by identifying steps and follow them up. To command a computer is not different from that, we “tell” it what to do by coding in a sequence for it to execute. In addition, we present to students the chemicals we use frequently. 

Discussion

Could you please tell me the steps you follow up to brush your teeth? How many steps are they? What would happen if you take steps out of order?
What products we use when we are brushing our teeth? Are these chemical products? Do you know how many chemical products we use frequently? How important these products are? 
There are many chemicals that are essential in human life. These chemicals are used in combined form or as few reagents. Over 1,000 of these chemicals are in use in our day to day.    

Video

Present the video about chemicals products.
