1. Describe the characteristics of a substitution reaction.
2. List the structures that are products of an addition reaction.
3. Describe esterification and saponification.
4. Describe the characteristics of the formation of a polymer.
This video contains a brief description of the substitution reaction:
These reactions usually take a long time and use organic solvents -- usually they are not encountered in the lab until studying Organic Chemistry at a college level.
There are several videos online demonstrating soapmaking, and I have performed a lab making soap in class. At this point in the school year, you may not want to spend the time on this lab, so I'm going to talk about one lab that is easy to pull together.
Here is a discussion of polymers (plastics) with a nice history of the origin of the need for polymers. Given our issues with the disposal and/or recycling of plastics, this is very interesting:
I have a description of this lab in my lab book "Chemistry on a Budget" at amazon.com -- it's only $20!
Each lab is presented with two possible report formats -- both labs use the same procedure but each has a different conclusion -- one with 10 questions to be answered as a conclusion, the other with a full laboratory report required. This gives the teacher the option of what type of report is desired, and each version is designed to be just two pages. This way the teacher can photocopy just one 2-sided page per student (saves paper).

An end of the year laboratory that might be fun is tie dyeing -- I will describe more about it in Sunday's post.
From now on, I am going to be posting on Sundays only. If I change the schedule, I'll let you know!
Have a good rest of the week!
