Module 2 Intro

Module 2—Chemical Compounds

Reflect and Connect

In this lesson you used Lewis structures and formulas to explain the formation of chemical compounds. Different models of the atom have been used throughout this unit.

Prepare a summary table of the different models of the atom that you have seen so far in this course. For each model, identify what aspects or features of the atom they attempt to represent. Place a copy of your summary in your course folder.

Reflect on the Big Picture

At the beginning of this lesson you considered how the equipment used for outdoor activities, like camping, has changed over the past century. How have other practices or activities changed as a result of chemical technologies that have been developed?

Talk to an elderly relative or visit a museum in your local area to observe medicines, clothing, tools, foods, or another aspect of human activity. Compare the materials used at that time with those used now. You will likely be amazed at the number of chemicals you encounter.

To keep track of your research, prepare a list that includes the name of the chemical involved, the substance it is found in, the purpose of the product, and the function of the chemical in the product. You may also choose to indicate whether a similar product was used by previous generations, and, if so, what substance (or chemical) was used for that purpose.

Save a copy of your list to your course folder. Later in the module you will be come back to this file and continue to work on it.
