Tasks:

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 of Ten

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.)

10. Log into the UT Online Homework System and add your name to the roster. (hw.utexas.edu/roster.html) You will have to invent a login name for yourself and a personal password. Write these down when you create them. Do not lose these. You will also be asked for an access password and a course number. These numbers are contained in my first e-mail response to you. If you cannot find them please e-mail me now to request them. (lbratche@accd.edu). If you have difficulties, leave me a voice mail at (210)274-9607. I will call you back within 48 hours. (10 min.)

11. Complete online homework #1. Be sure to read the student instructions before you begin. hw.utexas.edu (60 min.)
