Topic 4 Forces, Electricity and
Waves
Objectives
Forces
Learners first develop an understanding of how
forces can change the shape or motion of an object, considering both forces in
contact with objects and those which act over a distance. They investigate the
effects of friction on motion and explore ways of improving efficiency in
moving objects and systems. Study of speed and acceleration of an object leads
to an understanding of the relationship between its motion and the forces
acting on it. This is linked to transport safety. Learners develop their
understanding of the concept of buoyancy force and density.
Electricity
The learner’s knowledge about electricity begins
with knowing how to use it safely and this aspect is reinforced throughout
their learning. They develop their understanding of electricity as a means of
transferring energy by investigating circuits and building chemical cells.
Learners develop their understanding of series and parallel circuits and of
electrical and electronic components and apply their knowledge to the process
of designing, constructing, testing and modifying.
Vibrations and waves
Learners explore the nature of sound, light and
radiations in the electromagnetic spectrum. They use musical instruments to
explore the relationship between vibrations and sounds produced. They develop
their understanding of the properties of light and other forms of
electromagnetic radiations. They explore how different waves relate to the
environment and how we make use of them in health, medicine and communications

Topic 5 Materials and
Co-operative Learning
Objectives
Properties and uses of substances
By exploring the properties of different
substances and how they can be changed, learners gradually develop their
understanding of the connection between structure and properties. They explore
the development of new substances which have useful properties, and begin to
relate physical and chemical properties to models of atomic structure. Learners
begin to use symbols and chemical formulae as a way of communicating
information about elements and compounds.
Earth’s materials
Learners develop their knowledge and
understanding of substances that make up the Earth’s surface. Properties, uses
and methods of extraction of such materials are explored. Opportunities exist
to discuss the importance of carbon compounds derived from crude oil to our
lives.
Chemical changes
Learners gradually develop an understanding of
chemical changes. They consider processes which take place in the environment
and in the laboratory, and develop their understanding of the environmental
impact of some changes. They develop their understanding of energy changes in
chemical reactions and some of the factors affecting the rates of reactions.
Learners develop the use of chemical names, formulae and equations as a way of
conveying information about chemical changes.

Topic 6 Topical Science
Objectives
Topical science
By considering current issues of science,
learners increasingly develop their understanding of scientific concepts and
their capacity to form informed social, moral and ethical views. They reflect
upon and critically evaluate media portrayal of scientific findings.
