B.
Economic Importance of Solid Minerals
- Limestone
– used in cement production and building industry.
- Coal
– source of fuel and energy.
- Gold
– used for making jewelry and as a source of foreign exchange.
- Tin –
used in making cans, alloys, and electrical appliances.
- Uranium
– used for generating nuclear energy.
Step-by-Step
Presentation
Introduction
(5 minutes)
- Teacher begins with a question: “Have you ever seen
a bag of cement or jewelry? Do you know they come from resources beneath
the ground?”
- Students respond with their prior knowledge.
- Teacher explains that Nigeria is blessed with many resources
from non-living things, especially solid minerals.
Step
1: Identification of Solid Minerals (15 minutes)
- Teacher explains what non-living resources are.
- Teacher shows students the map/chart of Nigeria
with mineral deposits.
- Students identify and list minerals and their
locations.
- Teacher highlights major minerals and their areas:
limestone (Ogun, Enugu), coal (Enugu, Benue), tin (Jos), gold (Osun,
Zamfara), uranium (Adamawa).
- Teacher writes notes on the board while students copy.
Step
2: Economic Importance (10 minutes)
- Teacher asks: “Why do you think minerals like gold
or limestone are important to Nigeria?”
- Students attempt answers (e.g., “they are used for
building,” “they are sold for money”).
- Teacher explains clearly the economic importance of
each mineral.
- Students give real-life examples (cement in building,
gold jewelry, tin for cans).
Step
3: Class Discussion (5 minutes)
- Teacher leads a class discussion:
- How solid minerals contribute to industries (cement,
jewelry, energy).
- How minerals create jobs and generate money for the
country.
Evaluation
(3 minutes)
Teacher evaluates students with the
following questions:
- Mention four examples of solid minerals found in
Nigeria.
- Where can limestone and tin be found in Nigeria?
- State three economic importance of solid minerals.
(Expected answers:
- Limestone, coal, gold, tin, uranium.
- Limestone – Ogun/Enugu; Tin – Jos Plateau.
- Used in building, source of energy, foreign exchange,
job creation, electricity).
Assignment
(2 minutes)
- Write a short note on how mineral resources can help
reduce poverty in Nigeria.
Conclusion
- Teacher summarizes by reminding students that:
- Nigeria has many solid minerals like limestone,
coal, gold, tin, and uranium.
- Each mineral has its location and economic
importance.
- Minerals are important for industries, job
opportunities, foreign exchange, and national development.
