,QUESTION 1
1.1 Demonstrate your understanding of the “big ideas of science”
• Pedagogy they are linked to (2 marks):
The “big ideas of science” are linked to constructivist pedagogy, where learners build
new knowledge by connecting scientific concepts to prior experiences. They also relate
to inquiry-based learning because learners engage actively in questioning,
investigating, and applying scientific principles.
• Definition (6 marks):
The “big ideas of science” are broad, fundamental scientific principles that explain a
wide range of phenomena in the natural world. They are not isolated facts, but central
concepts that provide learners with a framework for making sense of science and
applying it in real-world contexts. These ideas help learners see the interconnectedness
of scientific knowledge and promote long-term scientific literacy.
• Where do they come from? (6 marks):
The concept of “big ideas of science” originated from research into science education
reforms, particularly the work of the Science Education Research Group and
international curriculum frameworks such as the Trends in International Mathematics
and Science Study (TIMSS) and the Programme for International Student
Assessment (PISA). They were further developed by the Association for Science
Education (ASE) and Harlen (2010), who emphasized the importance of teaching
science through key unifying concepts rather than fragmented facts.
• Six examples of the big ideas of science (6 marks):
1. All material in the Universe is made of very small particles.
2. Objects can affect one another at a distance (e.g., gravity, magnetism, and
electric forces).
, 3. Energy cannot be created or destroyed; it only changes from one form to
another.
4. The composition of the Earth and its atmosphere, and the processes that shape
them.
5. The solar system is a very small part of one of millions of galaxies in the
Universe.
6. The diversity of living organisms, including humans, can be explained by
evolution.
1.2 Differentiate between ancillary activities: modelling, art, drama, and field trips
(20 marks)
Ancillary activities are supportive teaching and learning strategies that enrich practical
science. They make science more engaging, interactive, and meaningful for learners.
Below is the differentiation:
a) Modelling
Understanding: Modelling involves creating representations (physical, visual, or
conceptual) of scientific phenomena that cannot be directly observed.
Example: Using a ball-and-stick model to represent the structure of a water
molecule (H₂O).
b) Art
Understanding: Art integrates creativity with science by encouraging learners to
use drawing, painting, or crafts to represent scientific ideas.
Example: Learners draw the water cycle (evaporation, condensation,
precipitation, collection) as a poster for classroom display.
c) Drama
