Introduction
Science for Beginners is a unit offered at the Foundation Level, developed for students
enrolling in Primary Teaching courses, without any formal science background.
This unit is aimed to develop students’ knowledge and understanding of basic science
concepts, skills and attitudes, which are of relevance to learning other science units
offered at the faculty of education. It also helps develop an awareness of the place of
science in modern society.
In this subject, science is viewed as a method of knowing, through which humans try to
understand the physical, material and biological components of their world. Doing
science is viewed as a means by which these components of our world are investigated
systematically through questioning and testing of ideas, by measurement and observation,
discussion and debate on validity and worthiness of ideas.
The above philosophy is used to guide the teaching strategies applied within this unit.
Learning through investigations is emphasized. However, teacher-led demonstrations,
library research and lectures are used where deemed appropriate.

The learning activities provided consider the relevance of curriculum content to the
students’ lives and aim to challenge the students to think and apply the scientific
understanding they have gained in the unit and from their personal experience.
Development of an attitude of curiosity, interest and inquisitiveness towards
understanding of our world is encouraged.
Learning objectives and outcomes
