Study Notes
Measurement Overview
- Measurement is the process of determining the magnitude of a quantity against an agreed standard.
- Two types of measurement methods: indigenous (local, traditional) and modern (scientific community).
Indigenous Methods of Measurement
- Indigenous methods are often passed down through generations and practiced locally.
- Focus on three main categories: length, mass, and time.
Length Measurement
- Length measures the distance between two points.
- Various indigenous units used in Ethiopia include:
- Hand-span: Distance from the tip of the little finger to the tip of the thumb when the hand is stretched.
- Digit: Width of an adult male fingertip.
- Cubit: Distance from the elbow tip to the tip of the middle finger with the arm extended.
- Foot: Distance from the back of the heel to the tip of the big toe.
- Pace: Distance from heel to heel of the same foot in one walking step.
- Arm span: Distance between the middle fingertips of both hands when arms are fully extended.
Mass Measurement
- Mass indicates the amount of matter in a substance, with various indigenous units:
- Weqet: Used primarily for measuring powdered gold.
- Quntal: A unit for measuring grain, equivalent to 100 kilograms.
- Feresula: Measures the mass of items like pepper and coffee, equal to 17 kilograms.
Time Measurement
- Time measures the duration of an interval.
- An indigenous method involves using the shadow of a tree:
- Shadow length varies throughout the day due to the Sun's position, allowing estimation of time.
- Shadows are longest in the morning and late afternoon and disappear at noon.
Activities
- Group activity encouraging students to measure a table's width using indigenous units.
- Discussion on the reliability of indigenous mass measurement methods.
- Observation of shadow lengths at different times to track time using natural indicators.
