  2. 2. WHAT IS HISTORY?Why Study History?People who study history are called historians. Historiansstudy causes and effects of historical events. A cause is areason that something happened. An effect is whathappened because of an event. Historians try to figure outwhy things happened. They use their understanding tothink about how those things make a difference today.Learning about the past helps us understand thepresent. It helps us decide what to do in the future.Knowing what went wrong in the past can help us makebetter decisions today when we face similar choices
  3. 3. era Measuring TimeA group of 10 years is called a decade. A group of 100years is called a century. Ten centuries grouped together iscalled a millennium, which is a period of 1,000 years.A period of several centuries is sometimes called an era .The earliest era is called prehistory. Prehistory is the timebefore people invented writing. The next period is calledAncient History. Then come the Middle Ages. Sometimesthe Middle Ages are called the medieval period. The eraafter the Middle Ages is Modern History. We live in the eraof Modern History.Decade=10 yearsCentury= 100 yearsMillennium=1,000 yearsEra=Several centuries
  4. 4. Why do we use calendars? To keep track of days and months, we use a calendar.Some cultures use calendars that are different from ours.Some calendars are arranged according to nature or theposition of the moon.Our modern calendar is based on one that started inancient Rome. Julius Caesar invented it. We call it theJulian calendar. It started counting years from the timethat Rome began. It was created with 365 days each yearand one extra day every fourth year, called a leap year.However, there was a problem with the Julian calendar. Itlost several minutes each year. That meant there was oneday lost every 128 years. It needed to be fixed.
  5. 5. Calendars Pope Gregory XIII decided to create a new calendar. Pope Gregory changed the starting date of his calendar. He begancounting years on his calendar from what he thought was the birthof Jesus. He also fixed the mistake from the Julian calendar. PopeGregory included leap years in his calendar, too. We call PopeGregory’s calendar the Gregorian calendar. Although there areother calendars, most of the world uses the Gregorian calendartoday.

  8. 8. archaeology Archaeology is the study of the past bylooking at what people left behind. Anarchaeologist digs in the earth for artifacts.
  9. 9. artifact An artifact is an object made by people. Tools,pottery, weapons, and jewelry are artifacts. Theyhelparchaeologists learn what life was like in thepast.
  10. 10. paleontology Paleontology studies prehistoric times.Paleontologists study fossils.
  11. 11. fossil Fossils are the remains of plant and animallife that have been preserved from an earliertime.
  12. 12. anthropology Anthropology is the study of humanculture.Anthropologists study artifacts and fossils, too.They look for clues about what people valuedand believed.
  13. 13. species A paleontologist named Donald Johanson made animportant discovery in Africa in 1974. He found theskeleton of an early human who lived more than3.2millionyears ago. He called the skeleton Lucy. Lucy belongedto adifferent species of early human. A species is a group ofanimals or humans. The members of a species are alikeinsome way. Lucy is the oldest human species thatscientistshave ever found. Lucy can help us learn more abouthowhumans developed.

  15. 15. evidence What Is the Evidence? Historians look at evidence to find out aboutthe past. Evidence is proof that something is true.Evidence might be an object, such as asoldier’s uniform or a scrap of pottery. Evidence might also be a document or bookthat was written during a historical event.
  16. 16. Primary source A primary source is a kind of evidence. Primarysources are created by people who saw or were part of anevent.Examples:A. LettersB diariesC. ToolsD. ClothingHistorians use primary sources to learn what people were thinking atthe time of the event.Primary sources can help historians explain events that happened longago.
  17. 17. Secondary source A secondary source is also evidence. Secondarysources are created after an event. They arecreated by people who were not part of the event.Examples:1. Textbooks2. EncyclopediaSecondary sources can give a broadview of historical events or people.However, newinformation can only come from primary sources.
  18. 18. Point of view Historians analyze the information in theirsources. They look for reasons that the sourcewas created. Then historians decide if thesource is reliable when it comes to its facts.Each source was written with a particularpoint of view, or attitude about people or life.
  19. 19. bias The author of a source uses his or her point ofview to decide what to include in thedocument. Sometimes a point of view is basedon feelings and not on facts. A judgment basedonly on feelings is called a bias. Sources witha bias cannotalways be trusted to be factual or true.
  20. 20. SOURCES THAT HISTORIANSUSE Written at the timeof the event. Eyewitness tohistory Reliable source forhistorians Includes letters,diaries, tools, andclothing Written after anevent Author did notwitness the event Contains facts aboutan event Includes textbooksand encyclopediasPRIMARY SOURCES Secondary Sources
  21. 21. scholarly Historians interpret information from primary sources to makeinferences. Making an inference means choosing the most likelyexplanation for the facts. Sometimes the inference is simple. Whenyou see someone with a wet umbrella, you can make the inferencethat it is raining. Making inferences about historical events is not soeasy. To make an inference, historians start with primary sources. Theyuse sources they already know are trustworthy. Next, they readsecondary sources. They think about the different points of view.Finally, they make an inference to explain what happened. Many historians write articles about their inferences. Most articlesare published in scholarly journals, or magazines. Scholarlymagazines are concerned with learning. Usually, other historiansread the articles to make sure the facts are correct. They decidewhether they agree with the inferences in the article. Historiansmust be careful to make inferences based on facts. They do notwant to show a bias in their writing.

  23. 23. conclusion A conclusion is a final decision that is reached byreasoning. It is like an inference. Historians draw conclusions about events of the past.They look for facts and evidence in their sources. Then, they use reasoning to draw a conclusion.Sometimes historians disagree in their conclusions. For example, some historians say that Genghis Khan wasa brutal warrior. They tell how he would destroy cities andkill people when he came to a new land. Other historiansdisagree. They say that Genghis Khan was a good ruler.His empire had a time of peace. Traders were safe to tradegoods. People were protected by good laws.

  25. 25. Planning Your Project The first step in researching a history topic is to choose a topic. Your topic should not be too broad or too narrow.To test your topic, look it up in an encyclopedia. If there is no entry for your topic, it may be too small. If there aremany entries, or a very long entry, the topic may be too large. After you choose a topic, decide what you want tolearn about. Create six questions to help you find out who, what, when, where, why, and how. Write each questionon a separate note card. As you find the information that answers each question, write it on the card. The next step is to collect your research materials. Start with an encyclopedia. Then visit the library to find a bookabout your subject. The sources must be nonfiction. Finally, look for articles on the Internet. Look at each bookand article to make sure it is trustworthy. Look for statements that are opinions. This can help you determinewhether the source is biased or untrustworthy. A good source will be full of facts. Remember, a fact is somethingthat can be proven by evidence. An opinion is an attitude toward something. It cannot be proven true or false. As you collect information about your topic, write a short phrase on your note card to help you remember thefacts. On the back of each card, make notes about the books where you found the information.Choose a topicCollect sourcesDecide if each source can be trusted
  26. 26. credentials Looking for information on the Internet is quick. However, finding sources you can trust can be tricky. Manyarticles on Web sites do not name the author. The reader cannot tell whether the person who wrote it is an experton the subject. A trustworthy article will include the author’s name and credentials. Credentials are evidence thatsomeone is an expert. The homepage of the Web site can give more clues about the trustworthiness of the article. If the article is on theWeb site of a university, government office, or museum, it is probably reliable. A good clue to find out about a Website is its online address, or URL. Look at the end of the URL. gov is a government site. This site probably has reliable information that is usually up to date. .edu is the site of a school or college. Most .edu sites pride themselves on accuracy. However, somedocuments may contain opinions as well as facts. .org is a nonprofit organizations usually end their URLs in These sites may be very accurate. However, theyoften contain opinions. You have now collected information about your topic. You have answered the questions on your cards. Now youmust sort your information into categories. Internet TipsIf you answer NO to any of the questionsbelow, the Web site is probably not a goodsource.• Can you tell who wrote the article?• Can you easily find out who isresponsible for the Web site?• Has the page been updated recently?• Does the writing show a bias toward onepoint of view?
  27. 27. plagiarize Putting all the facts of your research together canbe hard work. You should keep in mind someimportant guidelines for writing about history. One problem to watch out for when you arewriting aresearch paper is plagiarism. Plagiarism happenswhen awriter uses the exact words or ideas from anotherpersonwithout giving credit. Readers are wrongly led tobelieve
