Chapter Notes

**Key Definitions:**

  • History: Study of human past and societies
  • Fossils: Preserved plant/animal remains in rocks
  • Timeline: Sequence of dated events in order
  • Era: A distinct period of time
  • Gregorian calendar: 365-day calendar used worldwide
  • **Important Terms:**

  • CE (Common Era) = after year 1 CE
  • BCE (Before Common Era) = before year 1 CE
  • 1 Century = 100 years
  • 1 Millennium = 1,000 years
  • No year zero exists between 1 BCE and 1 CE
  • **Key Formula:**

    Years between BCE and CE = (BCE number) + (CE number) − 1

    Example: Buddha (560 BCE) to now (2024 CE) = 560 + 2024 − 1 = 2,583 years

    **Four Scientists Who Study the Past:**

    1. Geologists: Study Earth's physical features

    2. Palaeontologists: Study fossils of ancient life

    3. Anthropologists: Study human societies and cultures

    4. Archaeologists: Dig up human-made objects and remains

    **Don't Confuse:** AD/BCE (old terms) with CE/Common Era (new terms) — they mean the same thing! Archaeologists dig objects; palaeontologists study fossils.

    Important Board Questions

    What is history? [1 mark]

    Define history as the study of human past; mention that it helps us understand the present by learning from earlier times.

    Name any two scientists who study the past and write one line about what each one does. [2 marks]

    Choose from geologists, palaeontologists, anthropologists, or archaeologists; write their main work briefly (e.g., archaeologists dig up old objects).

    Explain with an example how a timeline helps us understand history. [3 marks]

    Describe that a timeline shows events in order; give an example like how we can see Buddha's birth (560 BCE) came before Jesus's birth (1 CE) without checking dates separately.

    Describe the four types of scientists who study the past. What does each one study? Create a simple table or list with their names and their main work. [5 marks]

    Include geologist (Earth features), palaeontologist (fossils), anthropologist (human societies), and archaeologist (buried objects); explain briefly what each discovers about the past.

    True or False: The year 2000 BCE came before the year 500 BCE. Give a reason for your answer. [2 marks]

    Remember that BCE numbers go backward in time; larger BCE numbers mean older times, so 2000 BCE is earlier than 500 BCE.
