(2) 1.1.2 Indigenous Knowledge (IK) (2) 1.1.3 Curriculum and assessment
policy standard (CAPS) (2) 1.2 Discuss the following and give examples. 2.1.1

QUESTION 1
1.1 Explain the following concepts.
1.1.1 Scientist (2)
A scientist is an individual who systematically gathers and analyzes data to understand the
natural and social world. They employ the scientific method, which involves observation,
hypothesis formation, experimentation, and conclusion drawing, to develop theories and laws
that explain phenomena. Scientists are characterized by their curiosity, critical thinking skills,
objectivity, and commitment to evidence-based reasoning.
1.1.2 Indigenous Knowledge (IK) (2)
Indigenous Knowledge (IK) refers to the accumulated body of knowledge, practices, and
beliefs of indigenous or local communities regarding their environment, social systems, and
cultural practices. It is often passed down through generations orally and is deeply rooted in the
specific cultural and ecological context of a particular community. IK encompasses a wide range
of domains, including agriculture, medicine, resource management, and social organization.
1.1.3 Curriculum and Assessment Policy Statement (CAPS) (2)
, The Curriculum and Assessment Policy Statement (CAPS) is a single, comprehensive, and
concise national policy document introduced in South Africa to outline the subjects taught in
schools, the time allocation for each subject, and the assessment requirements. It provides
detailed guidelines for teachers on what to teach and how to assess learning in each grade and
subject, aiming to ensure consistency and high standards in education across the country.
1.2 Discuss the following and give examples.
1.2.1 Traditional energy sources (12)
Traditional energy sources are those that have been utilized by communities for centuries, often
relying on locally available resources and simple technologies. These sources played a crucial
role in human development before the widespread adoption of fossil fuels and modern energy
systems. While some traditional energy sources are renewable and sustainable, others can have
environmental and health implications if not managed properly.
Examples of traditional energy sources include:
Biomass: This encompasses organic matter such as wood, agricultural residues (e.g.,
maize stalks, rice husks), and animal dung. It is burned directly for heating and cooking
or can be converted into other forms of energy like biogas.
o Example: Using firewood collected from a local forest for cooking over an open
fire.
o Example: Utilizing dried animal dung as fuel for heating in rural households.
Hydropower (small-scale): Utilizing the kinetic energy of flowing water to generate
mechanical power or electricity through simple waterwheels or small dams.
o Example: A waterwheel used to grind grains in a rural community.
o Example: A small-scale micro-hydroelectric system providing electricity to a
remote village.
Wind power (traditional windmills): Harnessing the kinetic energy of wind using
windmills for mechanical tasks like grinding grains or pumping water.
o Example: A traditional Dutch windmill used for grinding wheat into flour.
o Example: A simple wind pump used to draw water from a well for irrigation or
domestic use.
Solar energy (passive heating and drying): Utilizing the sun's energy for heating
spaces directly through architectural design (e.g., large south-facing windows) or for
drying agricultural products.
o Example: Designing a house with thick mud walls and small windows to stay cool
during the day and retain warmth at night.
o Example: Spreading grains or fruits under the sun to dry them for preservation.
Animal power: Using domesticated animals like oxen, horses, or donkeys to perform
tasks such as plowing fields, transporting goods, or powering simple machinery.
o Example: Using oxen to pull a plow in agricultural fields.
o Example: Employing donkeys to carry goods to the market.
