APPENDIX B

Succeeding in Your Chemistry Class

Your success in this course will depend on your abilityto apply some basic study skills to learning the mate-rial. Studying chemistry can be difficult, but you canmake it easier using simple strategies for dealing withthe concepts and problems. Becoming skilled in usingthese strategies will be your keys to success in this andmany other courses.

Reading the Text

• Read the assigned material before class so that theclass lecture makes sense. Use a dictionary to helpyou interpret vocabulary. Remember while readingto figure out what information is important.

Working together with others using Paired Readingand Discussion strategies can help you decide whatis important and clarify the material. (For more dis-cussion, see Other Reading Strategies on page 853.)

• Select a quiet setting away from distractions so thatyou can concentrate on what you are reading.

• Have a pencil and paper nearby to jot down notesand questions you may have. Be sure to get thesequestions answered in class. Power Notes (see page849) can help you organize the notes you take andprepare you for class.

• Use the Objectives in the beginning of each sectionas a list of what you need to know from the section.Teachers generally make their tests based on thetext objectives or their own objectives. Using theobjectives to focus your reading can make yourlearning more efficient. Using the K/W/L strategy(see page 851) can help you relate new material towhat you already know and what you need to learn.

Taking Notes in Class

• Be prepared to take notes during class. Have yourmaterials organized in a notebook. Separate sheetsof paper can be easily lost.

• Don’t write down everything your teacher says. Tryto tell which parts of the lecture are important andwhich are not. Reading the text before class willhelp in this. You will not be able to write downeverything, so you must try to write down only theimportant things.

• Recopying notes later is a waste of time and doesnot help you learn material for a test. Do it rightthe first time. Organize your notes as you are writ-ing them down so that you can make sense of yournotes when you review them without needing torecopy them.

Reviewing Class Notes

• Review your notes as soon as possible after class.Write down any questions you may have about thematerial covered that day. Be sure to get thesequestions answered during the next class. You canwork with friends to use strategies such as PairedSummarizing and L.I.N.K. (See page 853.)

• Do not wait until the test to review. By then youwill have forgotten a good portion of the material.

• Be selective about what you memorize. You cannotmemorize everything in a chapter. First of all, it istoo time consuming. Second, memorizing and under-standing are not the same thing. Memorizing topicsas they appear in your notes or text does not guar-antee that you will be able to correctly answer ques-tions that require understanding of those topics. Youshould only memorize material that you understand.Concept Maps and other Reading Organizers,Sequencing/Pattern Puzzles, and Prediction Guidescan help you understand key ideas and major con-cepts. (See pages 846, 852, and 854.)

Appendix B 845

Working Problems

In addition to understanding the concepts, the abilityto solve problems will be a key to your success inchemistry. You will probably spend a lot of time work-ing problems in class and at home. The ability to solvechemistry problems is a skill, and like any skill, itrequires practice.

• Always review the Sample Problems in the chapter.The Sample Problems in the text provide roadmaps for solving certain types of problems. Coverthe solution while trying to work the problemyourself.

• The problems in the Chapter Review are similar tothe Sample Problems. If you can relate an assignedproblem to one of the Sample Problems in thechapter, it shows that you understand the material.

• The four steps: Gather information, Plan yourwork, Calculate, and Verify should be the steps yougo through when working assigned problems.These steps will allow you to organize yourthoughts and help you develop your problem-solving skills.

• Never spend more than 15 minutes trying to solve aproblem. If you have not been able to come upwith a plan for the solution after 15 minutes, addi-tional time spent will only cause you to becomefrustrated. What do you do? Get help! See yourteacher or a classmate. Find out what it is that youdo not understand.

• Do not try to memorize the Sample Problems;spend your time trying to understand how the solu-tion develops. Memorizing a particular sampleproblem will not ensure that you understand it wellenough to solve a similar problem.

• Always look at your answer and ask yourself if it isreasonable and makes sense. Check to be sure youhave the correct units and numbers of significantfigures.

Completing Homework

Your teacher will probably assign questions and prob-lems from the Section Reviews and Chapter Reviewsor assign Concept Review worksheets. The purpose ofthese assignments is to review what you have coveredin class and to see if you can use the information toanswer questions or solve problems. As in reviewingclass notes, do your homework as soon after class aspossible while the topics are still fresh in your mind.Do not wait until late at night, when you are morelikely to be tired and to become frustrated.

Reviewing for an exam

• Don’t panic and don’t cram! It takes longer tolearn if you are under pressure. If you have fol-lowed the strategies listed here and reviewed alongthe way, studying for the exam should be lessstressful.

• When looking over your notes and concept maps,recite ideas out loud. There are two reasons forreciting:

1. You are hearing the information, which is effec-tive in helping you learn.

2. If you cannot recite the ideas, it should be a cluethat you do not understand the material, and youshould begin rereading or reviewing the materialagain.

• Studying with a friend provides a good opportunityfor recitation. If you can explain ideas to yourstudy partner, you know the material.

Taking an exam

• Get plenty of rest before the exam so that you canthink clearly. If you have been awake all nightstudying, you are less likely to succeed than if youhad gotten a full night of rest.

• Start with the questions you know. If you get stuckon a question, save it for later. As time passes andyou work through the exam, you may recall theinformation you need to answer a difficult questionor solve a difficult problem.

Good luck!

Making concept maps can help you decide what mate-rial in a chapter is important and how to efficientlylearn that material. A concept map presents key ideas,meanings, and relationships for the concepts beingstudied. It can be thought of as a visual road map ofthe chapter. Learning happens efficiently when youuse concept maps because you work with only the keyideas and how they fit together.

The concept map shown as Map A was made fromvocabulary terms from the first few chapters of thebook. Vocabulary terms are generally labels for con-cepts, and concepts are generally nouns. In a conceptmap, linking words are used to form propositions that

connect concepts and give them meaning in context.For example, on the map above, “matter is describedby physical properties” is a proposition.

Studies show that people are better able to remembermaterials presented visually. A concept map is betterthan an outline because you can see the relationshipsamong many ideas. Because outlines are linear, thereis no way of linking the ideas from various sections ofthe outline. Read through the map to become familiarwith the information presented. Then look at the mapin relation to all of the text pages in the first fewchapters; which gives a better picture of the importantconcepts—the map or the full chapters?

APPENDIX B

To Make a Concept Map

1. List all the important concepts.

We’ll use some of the boldfaced and italicizedterms from the chapter “Matter and Energy.”

matter mixturecompound pure substanceelement heterogeneous mixturehomogeneous mixture

• From this list, group similar concepts together. Forexample, one way to group these concepts would

be into two groups—one that is related to mixturesand one that is related to pure substances.

mixture pure substanceheterogeneous mixture compoundhomogeneous mixture element

2. Select a main concept for the map.

We will use matter as the main concept for this map.

3. Build the map by placing the concepts according totheir importance under the main concept. For thismap the main concept is matter.

One way of arranging the concepts is shown in Map B.

4. Add linking words to give meaning to the arrange-ment of concepts.

When adding the links, be sure that each proposi-tion makes sense. To distinguish concepts fromlinks, place your concepts in circles, ovals, or rec-tangles, as shown in the maps. Then make cross-links. Cross-links are made of propositions andlines connecting concepts across the map. Linksthat apply in only one direction are indicated withan arrowhead. Map C is a finished map covering themain ideas listed in Step 1.

Making maps might seem difficult at first, but theprocess forces you to think about the meanings andrelationships among the concepts. If you do notunderstand those relationships, you can get help early on.

Practice mapping by making concept maps abouttopics you know. For example, if you know a lot abouta particular sport, such as basketball, or if you have aparticular hobby, such as playing a musical instru-ment, you can use that topic to make a practice map.By perfecting your skills with information that youknow very well, you will begin to feel more confidentabout making maps from the information in achapter.

Remember, the time you devote to mapping will payoff when it is time to review for an exam.

1. Classify each of the following as either a concept orlinking word(s).

a. classification

b. is classified as

c. forms

d. is described by

APPENDIX B

Making Power NotesPower notes help you organize the chemical conceptsyou are studying by distinguishing main ideas fromdetails. Similar to outlines, power notes are linear inform and provide you with a framework of importantconcepts. Power notes are easier to use than outlinesbecause their structure is simpler. Using the powernotes numbering system you assign a 1 to each mainidea and a 2, 3, or 4 to each detail.

Power notes are an invaluable asset to the learningprocess, and they can be used frequently throughoutyour chemistry course. You can use power notes toorganize ideas while reading your text or to restructureyour class notes for studying purposes.

To learn to make power notes, practice first by usingsingle-word concepts and a subject you are especiallyinterested in, such as animals, sports, or movies. As youbecome comfortable with structuring power notes, inte-grate their use into your study of chemistry. For an eas-ier transition, start with a few boldfaced or italicizedterms. Later you can strengthen your notes by expand-ing these single-word concepts into more-detailedphrases and sentences. Use the following general for-mat to help you structure your power notes.

Power 1: Main idea

Power 2: Detail or support for power 1

Power 3: Detail or support for power 2

Power 4: Detail or support for power 3

1. Pick a Power 1 word from the text.

The text you choose does not have to come straightfrom your chemistry textbook. You may be makingpower notes from your lecture notes or from an out-side source. We’ll use the term atom found in thechapter entitled “Atoms and Moles” in your text-book.

Power 1: Atom

2. Using the text, select some Power 2 words to sup-port your Power 1 word.

We’ll use the terms nucleus and electrons, which aretwo parts of an atom.

Power 1: Atom

Power 2: Nucleus

Power 2: Electrons

3. Select some Power 3 words to support your Power 2words.We’ll use the terms positively charged andnegatively charged, two terms that describe thePower 2 words.

Power 1: Atom

Power 2: Nucleus

Power 3: Positively charged

Power 2: Electrons

Power 3: Negatively charged

4. Continue to add powers to support and detail themain idea as necessary.

There are no restrictions on how many power num-bers you can use in your notes. If you have a mainidea that requires a lot of support, add more powersto help you extend and organize your ideas. Be surethat words having the same power number have asimilar relationship to the power above. Power 1terms do not have to be related to each other. Youcan use power notes to organize the material in anentire section or chapter of your text. Doing so willprovide you with an invaluable study guide for yourclassroom quizzes and tests.

Power 1: Atom

Power 2: Nucleus

Power 3: Positively charged

Power 3: Protons

Power 4: Positively charged

Power 3: Neutrons

Power 4: No charge

Power 2: Electrons

Power 3: Negatively charged

Practice

1. Use a periodic table and the power notes structurebelow to organize the following terms: alkaline-earthmetals, nonmetals, calcium, sodium, halogens, met-als, alkali metals, chlorine, barium, and iodine.

Two-column notes can be used to learn and reviewdefinitions of vocabulary terms, examples of multiple-step processes, or details of specific concepts. The two-column-note strategy is simple: write the term, mainidea, step-by-step process, or concept in the left-handcolumn, and the definition, example, or detail on theright.

One strategy for using two-column notes is to organ-ize main ideas and their details. The main ideas fromyour reading are written in the left-hand column ofyour paper and can be written as questions, keywords, or a combination of both. Details describingthese main ideas are then written in the right-handcolumn of your paper.

1. Identify the main ideas. The main ideas for a chap-ter are listed in the section objectives. However,you decide which ideas to include in your notes.For example, here are some main ideas from theobjectives in Section 4-2.

• Describe the locations in the periodic table and thegeneral properties of the alkali metals, alkaline-earth metals, the halogens, and the noble gases.

2. Divide a blank sheet of paper into two columnsand write the main ideas in the left-hand column.Summarize your ideas using quick phrases that areeasy for you to understand and remember. Decidehow many details you need for each main idea, andwrite that number in parentheses under the mainidea.

3. Write the detail notes in the right-hand column. Besure you list as many details as you designated inthe main-idea column. Here are some main ideasand details about some of the groups in thePeriodic Table.

The two-column method of review is perfect whetheryou use it to study for a short quiz or for a test on thematerial in an entire chapter. Just cover the informa-tion in the right-hand column with a sheet of paper,and after reciting what you know, uncover the notesto check your answers. Then ask yourself what elseyou know about that topic. Linking ideas in this waywill help you to gain a more complete picture ofchemistry.

APPENDIX B

Using the K/W/L/ Strategy

What I LearnedWhat I want to KnowWhat I Know• gas has no definite shape

or volume

• liquid has no definite shape, but has definite volume

• how gas, liquid, and solid states are related to particles

• molecules in solid and liquid statesare close together, but are far apart in gas state

• molecules in solid state have fixedpositions, but molecules in liquid and gas states can flow

• mixtures are combinations ofpure substances

• pure substances have fixed compositions and definite properties

• how mixtures and pure substances are different

• solid has definite shape and volume

• mixture is a combination of substances

• pure substance has only one component

The K/W/L strategy stands for “what I Know—what IWant to know—what I Learned.” You start by brain-storming about the subject matter before reading theassigned material. Relating new ideas and concepts tothose you have learned previously will help you betterunderstand and apply the new knowledge you obtain.The section objectives throughout your textbook areideal for using the K/W/L strategy.

1. Read the section objectives. You may also want toscan headings, boldfaced terms, and illustrationsbefore reading. Here are two of the objectives fromSection 1-2 to use as an example.

• Explain the gas, liquid, and solid states in termsof particles.

• Distinguish between a mixture and a puresubstance.

2. Divide a sheet of paper into three columns, andlabel the columns “What I Know,” “What I Wantto Know,” and “What I Learned.”

3. Brainstorm about what you know about the infor-mation in the objectives, and write these ideas inthe first column. Because this chart is designed pri-marily to help you integrate your own knowledgewith new information, it is not necessary to writecomplete sentences.

4. Think about what you want to know about theinformation in the objectives, and write these ideasin the second column. Include information fromboth the section objectives and any other objec-tives your teacher has given you.

5. While reading the section or afterwards, use thethird column to write down the information youlearned. While reading, pay close attention to anyinformation about the topics you wrote in the“What I Want to Know” column. If you do not findall of the answers you are looking for, you mayneed to reread the section or reference a secondsource. Be sure to ask your teacher if you still can-not find the information after reading the section asecond time.

It is also important to review your brainstormed ideaswhen you have completed reading the section.Compare your ideas in the first column with the infor-mation you wrote down in the third column. If youfind that some of your brainstormed ideas are incor-rect, cross them out. It is extremely important to iden-tify and correct any misconceptions you had prior toreading before you begin studying for your test.

APPENDIX B

Using Sequencing/Pattern PuzzlesYou can use pattern puzzles to help you remembersequential information. Pattern puzzles are not just atool for memorization. They also promote a greaterunderstanding of a variety of chemical processes, fromthe steps in solving a mass-mass stoichiometry prob-lem to the procedure for making a solution of speci-fied molarity.

Here’s a step-by-step example showing how to make apattern puzzle, and how to use it to help you study.For other topics that require remembering informa-tion in a particular order, just follow the same steps.

1. Write down the steps of a process in your ownwords.

For an example, we will use the process for con-verting the amount of a substance in moles to massin grams. (See Sample Problem D in the chapter on“Atoms and Moles.”)

On a sheet of notebook paper, write down one stepper line, and do not number the steps.

Do not copy the process straight from your text-book. Writing the steps in your own words pro-motes a more thorough understanding of theprocess.

You may want to divide longer steps into two orthree shorter steps.

2. Cut the sheet of paper into strips with only onestep per strip of paper. Shuffle the strips of paperso that they are out of sequence.

3. Place the strips in their proper sequence. Confirmthe order of the process by checking your text oryour class notes.

Pattern puzzles are especially helpful when you arestudying for your chemistry tests. Before tests, useyour puzzles to practice sequencing and to review thesteps of chemistry processes. You and a classmate canalso take turns creating your own pattern puzzles ofdifferent chemical processes and putting each other’spuzzles in the correct sequence. Studying with a class-mate in this manner will help make studying fun andwill enable you to help each other.

APPENDIX B

Other Reading StrategiesBrainstorming

Brainstorming is a strategy that helps you recognizeand evaluate the knowledge you already have beforeyou start reading. It works well individually or ingroups. When you brainstorm, you start with a centralterm or idea, then quickly list all the words, phrases,and other ideas that you think are related to it.

Because there are no “right” or “wrong” answers, youcan use the list as a basis for classifying terms, devel-oping a general explanation, or speculating about newrelationships. For example, you might brainstorm a listof terms related to the word element before you readabout elements early in the textbook. The list mightinclude gold, metals, chemicals, silver, carbon, oxygen,and water. As you read the textbook, you mightdecide that some of the terms you listed are not ele-ments. Later, you might use that information to helpyou distinguish between elements and compounds.

Building/Interpreting Vocabulary

Using a dictionary to look up the meanings of prefixesand suffixes as well as word origins and meaningshelps you build your vocabulary and interpret whatyou read. If you know the meaning of prefixes likekilo- (one thousand) and milli- (one thousandth), youhave a good idea what kilograms, kilometers, mil-ligrams, and millimeters are and how they are differ-ent. (See Appendix A for a list of SI Prefixes.)

Knowledge of prefixes, suffixes, and word origins canhelp you understand the meaning of new words. Forexample, if you know the prefix –poly comes from theword meaning many, it will help you understand whatpolysaccharides and polymers are.

Reading Hints

Reading hints help you identify and bookmark impor-tant charts, tables, and illustrations for easy reference.For example, you may want to use a self-adhesivenote to bookmark the periodic table in the chapterdescribing it or on the inside back cover of your bookso you can easily locate it and use it for reference asyou study different aspects of chemistry and solveproblems involving elements and compounds.

Interpreting Graphic Sources of Information

Charts, tables, photographs, diagrams, and other illus-trations are graphic, or visual, sources of information.The labels and captions, together with the illustrationshelp you make connections between the words andthe ideas presented in the text.

Reading Response Logs

Keeping a reading response log helps you interpretwhat you read and gives you a chance to express yourreactions and opinions about what you have read.Draw a vertical line down the center of a piece ofpaper. In the left-hand column, write down or makenotes about passages you read to which you havereactions, thoughts, feelings, questions, or associations.In the right-hand column, write what those reactions,thoughts, feelings, questions, or associations are. Forexample, you might keep a reading response log whenstudying about Nuclear Energy.

Other Studying StrategiesComparing and Contrasting

Comparing and contrasting is a strategy that helpsyou note similarities and differences between two ormore objects or events. When you determine similari-ties, you are comparing. When you determine differ-ences, you are contrasting.

You can use comparing and contrasting to help youclassify objects or properties, differentiate betweensimilar concepts, and speculate about new relation-ships. For example, as you read Chapters 1 and 2 youmight begin to make a table in which you compareand contrast metals, nonmetals, and metalloids. As youcontinue to learn about these substances in the chapteron the Periodic Table, you can add to your table, givingyou a better understanding of the similarities and dif-ferences among elements.

Identifying Cause and Effect

Identifying causes and effects as you read helps youunderstand the material and builds logical reasoningskills. An effect is an event or the result of some action.A cause is the reason the event or action occurred.Signal words, such as because, so, since, therefore, as aresult, and depends on, indicate a cause-and-effect relationship.

You can use arrows to show cause and effect. Forexample, you might write this cause-and-effect rela-tionship as you read about gases: At constant pressure,increase in temperature (cause) → increase in gasvolume (effect).

Making a Prediction Guide

A prediction guide is a list of statements about whichyou express and try to justify your opinions based onyour current knowledge. After reading the material,you re-evaluate your opinion in light of what you

learned. Using prediction guides helps you evaluateyour knowledge, identify assumptions you may havethat could lead to mistaken conclusions, and form anidea of expected results.

1. Read the statements your teacher writes on theboard. For example, look at the five statements from Dalton’s theory listed in the chapter “Atomsand Moles.”

2. Decide whether you think each statement is true orfalse and discuss reasons why you think so.

3. After reading the section, re-evaluate your opinionof each statement. Discuss why your opinionchanged or remained the same. Find passages in thetext that account for the change of reinforcement ofyour opinions. For example, you might have agreedwith all five statements from Dalton’s theory beforereading the text. Then, after reading about atomsand subatomic particles, you might have changedyour opinion about the first statement.

Reading Organizers

Arranging information in tables or two-column notesmakes it easier for you to understand. A table consistsof rows and columns. The column headings and rowheadings list the items and the characteristics to beorganized in the table. Here is a table for organizinginformation about the particles that make up an atom.

Particle Symbol Charge Mass No.

electron e− −1 0

proton p+ +1 1

neutron n0 0 1

Cooperative Learning TechniquesReading with a Partner

Reading with a partner is a strategy that can help youunderstand what you read and point out where moreexplanation is needed.

1. First read the text silently by yourself. Use self-adhesive notes to mark those parts of the text thatyou do not understand. For example, you mighthave difficulty with some of the material aboutquantum numbers, while another student under-stands quantum numbers but has trouble with elec-tron configurations.

2. Work with a partner to discuss the passages each ofyou marked. Take turns listening and trying to clar-ify the difficult passages for each other. Together,study the related tables and illustrations andexplain to each other how they relate to the text.

3. For concepts that need further explanation, worktogether to formulate questions for class discussionor for your teacher to answer.

Using L.I.N.K.

The L.I.N.K. strategy stands for List, Inquire, Notes,Know. It is similar to the K/W/L strategy, but youwork as a class or in groups.

1. Brainstorm all the words, phrases, and ideas associ-ated with the term your teacher provides.Volunteers can keep track of contributions on theboard or on a separate sheet of paper.

2. Your teacher will direct you in a class or group dis-cussion about the words and ideas listed. Now isthe time to inquire, or ask your teacher and otherstudents for clarification of the listed ideas.

3. At the end of the discussion, make notes abouteverything you can remember. Look over yournotes to see if you have left anything out.

4. See what you now know about the given conceptbased on your own experience and the discussion.

Summarizing/Paired Summarizing

A summary is a brief statement of main ideas orimportant concepts. Making a summary of what youhave read provides you with a way to review what you

have learned, see what information needs further clari-fication, and helps you make connections to previouslystudied material.

Paired summarizing helps strengthen your ability toread, listen, and understand. It is especially useful whena section of text has several subdivisions, each dealingwith different topics.

1. First read the material silently by yourself.

2. Then you and your partner take turns being the “lis-tener” and the “reteller.” The reteller summarizesthe material for the listener, who does not interruptuntil the reteller has finished. If necessary, thereteller may consult the text, and the listener mayask for clarification. The listener then states anyinaccuracies or omissions made by the reteller.
