UNIT 11.1: SCIENCE AND TECHNOLOGY

Meaning and Distinction

1. Meaning of Science

Science is the systematic study of the natural and physical world through observation, experimentation, and reasoning in order to discover facts and laws.

Science seeks to answer questions such as:

• Why does rain fall?

• How do plants grow?

• What causes diseases?

Science focuses on knowledge and understanding.

Characteristics of Science

• It is based on facts and evidence

• It involves experimentation

• It aims at discovering new knowledge

• It explains natural phenomena

Examples of Science

• Biology (study of living things)

• Chemistry (study of substances)

• Physics (study of energy and matter)

---

2. Meaning of Technology

Technology is the practical application of scientific knowledge to solve human problems and improve living conditions.

Technology focuses on how to use scientific knowledge to make life easier and more efficient.

Characteristics of Technology

• It is practical and skill-based

• It involves tools, machines, and processes

• It improves productivity and efficiency

• It solves everyday problems

Examples of Technology

• Mobile phones

• Tractors

• Computers

• Medical equipment

• Machines in factories

3. Distinction Between Science and Technology

Science	Technology
Deals with discovering knowledge	Deals with applying knowledge
Explains why things happen	Shows how things are done
Concerned with theories and laws	Concerned with tools and machines
Example: studying electricity	Example: using electricity to power machines

Explanation:
Science provides the knowledge, while technology uses that knowledge to produce useful products and services. Without science, technology cannot develop, and without technology, science has little practical value.

UNIT 11.3: RESOURCES AND DEVELOPMENT

Meaning of Resources

Resources are all the natural and human materials that are used to satisfy human needs and promote development.

Resources are essential for economic growth and national development.

---

Types of Resources

1. Natural Resources

These are resources obtained directly from nature.

Examples:

• Minerals (gold, bauxite)

• Forests

• Water bodies

• Land

• Sunlight

---

2. Human Resources

These refer to the skills, knowledge, and abilities of people.

Examples:

• Teachers

• Doctors

• Engineers

• Farmers

• Scientists

---

3. Capital Resources

These are man-made tools used to produce goods and services.

Examples:

• Machines

• Buildings

• Roads

• Factories

---

4. Financial Resources

These include money used for development.

Examples:

• Government revenue

• Loans

• Taxes

• Investments

---

Inter-relationship Among Resources

Resources do not work independently; they depend on one another.

Explanation of the Inter-relationship

• Natural resources need human resources to extract and manage them

• Human resources require education and training, which need financial resources

• Capital resources are created using natural and financial resources

• Technology helps in the efficient use of all resources

Example:
Gold (natural resource) cannot be mined without skilled workers (human resource), machines (capital resource), and money (financial resource).

LEARNING OUTCOMES EXPLAINED (LEVEL 2–4)

1. Distinguish Science from Technology

Learners should be able to explain that science deals with knowledge and discovery, while technology applies that knowledge to solve problems.

---

2. Assess the Role of Science in Development

Learners should evaluate how science contributes to agriculture, health, industry, and education, and how it improves the quality of life.

---

3. Analyse Resource Utilization

Learners should examine how resources are used, identify misuse or waste, and suggest ways to manage resources sustainably for development.

---

CONCLUSION

Science, technology, and resources are interconnected and essential for national development. Proper application of science, effective use of technology, and wise management of resources are key factors in Ghana’s development.
