Unit I - Uncertainty in Measurement

 * The major vocabulary words and ideas of this unit are detailed in the following presentations. ||
 * [[file:Unit 1 Part 1 - Measurement.pdf]] ||  ||

This table contains a list of all the lessons in the unit. Quizzes and Tests
 * Concept || Assignment || Pages in the Textbook || Worksheet || Date Assigned ||
 * Units in Measurements || Complete the worksheet to understand the SI System, metric prefixes, and the use of proportions in conversions. Note: conversions between Celcius and Fahrenheit are not part of the course content. || Section 1.2: Pages 14 to 21. Also read section 3.3 of the Addison-Wesley Chemistry test (this reading is a photocopied handout). || [[file:Worksheet I-1 Unit Conversions.pdf]] || August 28, 2012 ||
 * Uncertainty in Measurement || The role of uncertainty in a measurement can be understood as a change in the last digit of a measurement. The uncertainty is commonly defined as one half of the smallest division on the measuring scale. ||  || [[file:Worksheet I-2 Measurement Uncertainty.pdf]] || August 30 ||
 * Significant Figure (Definition) || Read the ChemTeam page about [|uncertainty in measurement]. Complete the sample problems which are given on that page. Then, complete the front side only of Worksheet I-3. While completing the worksheet, you should open the ChemTeam page which lists the [|significant digit rules]. || Read pages 56 and 57 in Chapter 3 of the Addison-Wesley Chemistry text (this reading is a photocopied handout). || [[file:Worksheet I-3 Significant Digits.pdf]] || September 3 ||
 * Density ||  ||   || [[file:Worksheet I-4 Density Calculations.pdf]] || Half of the problems assigned on September 14 (problems 1-4 and objects A and B) ||
 * Date || Assessment || Content ||
 * 9/7 || Quiz || This quiz will cover the first three lessons: units, uncertainty, significant figures. ||
 * 9/21 || Quiz || This quiz will cover the density and significant digits in calculations (worksheet 3) ||
 * 9/27 || Unit Test ||  ||

To review the concepts from this unit, use the ChemTeam page. If you explore this page, you will find a lot of helpful information and practice problems.
 * 1) In the tutorials section, you should study all the tutorials (Number 1 can be skipped - we will review scientific notation very carefully in February). Each of the tutorials has practice problems for you to try.
 * 2) In the problem sets, I recommend the significant figures worksheet. The density worksheets are more challenging than the material you will find on tests and quizzes.
 * 3) A VERY USEFUL essay is found on the bottom right-hand corner of the page. It is called "Measuring Underlies Significant Figures." I recommend that you study this essay.

 * Test Review || [[file:Energy and pendulums.pdf]] ||  || In the Ohio State Quizzes, use the first quiz bank to review calculations involving specific heat. The ninth quiz from the bottom is called "Heat Energy and Simple Calorimetry." You can complete all of the questions in this quiz. Remember, every time you re-enter the quiz, you will see three new questions. One small note: these quizzes use the unit "kilocalorie." 1 calorie = 4.184 Joules, 1 kilocalorie = 1000 calories, so 1 kilocarie = 4184 Joules.

The Thermochemistry page from ChemTeam also gives you some notes to read and problems to try. Here are the most important tutorials, in order of importance: Below the tutorials are some problem sets.
 * #2, specific heat
 * #1, the heat curve (time-temperature graph)
 * #6, determine final temperature
 * #8, a brief survey of energy, work, heat, and temperature
 * #3 and #4, Molar heat of vaporization and fusion. Please note that one mole of water is equal to 18.0 g of water.
 * Start with the worksheets #1 an #2.
 * Next, study the page called "Sample problems which use two or three parts of the time-temperature graph." In these sample problems, you will see the word "mole." A mole is equal to 18.0 g of water. It is an idea we use in chemistry. To understand the problems on this || Unit Test on Tuesday - March 20, 2012 ||

 * Spring Semester Exam Review**

Here is a powerpoint with questions from the past. The questions are very detailed about waves; there is more information about waves than you will need for your exam.



Students in 9th grade during the 2012-13 school year are not required to read past this point.

 * Name of Unit || Presentations to download || Chapters that relate to this material ||
 * Unit III - Forces ||  || [[file:Chapter 10 Study Guide.pdf]] ||
 * || Read this link to learn about electric fields. Click on "Science Trek" in the bottom right hand of the page, then choose the first link, "Electromagnetic Waves." || The University of Colorado website shows the behavior of charges in an electric field. If you read through the chapter on Electromagnetic Waves, you will quickly locate an applet that lets you place test charges inside an electric field. ||
 * 2nd Semester Exam Review || [[file:Grade 9 Semester 2 Exam Review.pdf]] || Here is the presentation we used in class. ||
 * Evaluate yourself || Use this time of the year to prepare for next year. Reflect on your ability to stay organized and make a list of items to purchase for your study area at home. || Were you able to keep important papers from the entire semester, or did you lose tests and quizzes? Is your study area at home still neat? Do you carry all your important papers in your bookbag? If so, find a way to move them into a binder at home. How does your locker look right now? Do you use all the things in your locker each week, or do some things sit there for a longer time? Can you move those out of your locker? Are the files on your computer organized? How about your files on S-share? Your bookmarks? What will you keep for next year? Begin to close the books for 9th grade. In twelve weeks, you will be sophomores. ||
