This module introduces an overview of the composition of matter and the way scientists study matter. A brief history of how things have progressed through the 19th century ending in DNA manipulation is followed by a discussion of atoms, basic chemical reactions and symbolism, chemical formulas, measurements, and number usage in science. Finally a piece on modern science and the media. It is important to get this overview well situated in your brain. The ideas set forth here are the bases for the rest of your work in CHEM 20.
OrientationOur study of chemistry begins with an overview of the composition of matter and the way that scientists study materials and their reactions. Exercises in getting to know measurements will utilize a calculator. Have one ready. The text gives a nice history of scientific discovery related to the atom while your ChemActivities this week will ensure you grasp the use of symbols and tools of chemistry.

Discovery and/or ExplorationThe group work for this week focuses on numbers, units, the metric system and converting measurements in one unit into another. You are required to work together to create a wiki which covers the material in each ChemActivity. For the most points, it is better to post thought process rather than just an answer. Each student in the group should do selected questions. You can spread them out, or have each student concentrate on a specific section. Look over the ChemActivity and decide how to best progress. Remember that you must do all of the questions for yourself on paper so you have the notes. But, you will not be answering all the questions online. 5 students, 20 questions = 4 questions each online.

Text ReadingChapter one of your text.
Post a reflection in the chapter discussion area EV_Reading.
The text gives a nice historical reference point for the development of the atomic theory and science in general. Pay particular attention to the difference between an atom and the element. Hypothesis development plays a larger role in chemistry than many other sciences as we cannot see atoms or the particles they contain. Definition of terms such as pure are different in chemistry then in advertisements in society. Learning how chemists use terms is an important aspect of this class. Review your terms early and often. Lastly, an introduction to measurements, various units, and conversion factors are covered.
