Social Studies Skills
Primary vs. secondary sources, timelines, graphs, fact vs. opinion, cause & effect, and book parts
📜 Worksheet 1 — Primary vs. Secondary Sources
A primary source comes from someone who was actually there. A secondary source is written by someone who learned about the event later. Read each description and decide which type it is.
Quick Guide
- Primary sources: diary entries · personal letters · photographs taken at the time · speeches given by the person · eyewitness accounts · official documents signed at the time (Declaration of Independence)
- Secondary sources: textbooks · encyclopedias · biographies (written by someone else) · documentaries · museum exhibits · news articles written after the event
- Trick: Ask "Was the author there when it happened?" If yes → primary. If no → secondary.
📅 Worksheet 2 — Reading Timelines & Graphs
Use the timeline and bar graph below to answer each question.
How to Read a Timeline
- Earlier dates are on the left; later dates are on the right
- To find how many years between two events: subtract the earlier year from the later year
- Events are listed in chronological order (time order)
How to Read a Bar Graph
- Look at the title to know what is being compared
- Read the scale on the side to know what each bar height means
- The tallest bar = most; the shortest bar = least
- To find the difference between two bars: subtract the smaller from the larger
🧠 Worksheet 3 — Fact, Opinion, Cause & Effect, and Book Parts
Mixed practice covering three key social studies skills.
Fact vs. Opinion
- Fact: can be proven true or false using evidence. "Texas became a state in 1845."
- Opinion: a personal belief, feeling, or judgment. Cannot be proven. Often contains words like best, worst, should, I think, I believe, most important.
Cause & Effect
- Cause = why something happened · Effect = what happened as a result
- Clue words: because, as a result, therefore, so, led to, caused
Parts of a Book
- Table of Contents: lists chapters in order, at the FRONT of the book — tells you what page each chapter starts on
- Index: alphabetical list of topics at the BACK — tells you exact page numbers where that topic appears
- Glossary: dictionary of key terms at the BACK — gives definitions of important words used in the book
