At the end of each task is an estimate of the
amount of time you should spend on that task.
1. Read and study chapter 1 in the textbook. (2
hrs.)
2. Use the Java
Applet on states of matter to explore the nature of gases,
liquids, and solids. (5 min.)
3. Follow the link to notes on physical
and chemical properties and changes, and study the vocabulary
and concepts in these notes. (20 min.)
4. In order to learn about scientific expression of magnitude,
follow the links below. Study the concepts addressed and follow the
directions on these web pages. (20 min.)
How big is big? Exponential Notation - Powers

How small is small? Look at small things through a simulated
electron microscope.
5. In order to learn about scientific
measurement tools and the metric system, follow the link
below. Follow the guidelines given. (20 min.)
6. Follow the link and the directions to learn the rules
for counting significant digits
and for rounding calculated answers. At the end of this
section, there is an online Java
applet that provides a good check for understanding. If
you think you already know how to count significant digits and how
to round answers, go directly to the Java applet. (30
min.)
7. Learn to use dimensional
analysis as a problem solving technique by following the
link provided. (30 min.)
8. Practice using the density
formula. (30 min.)
9. Learn about the relationship between temperature and heat,
and how the mass of the sample is a factor in heat transferred. Practice
using the heat capacity formula.
(30 min.)
