Learning environments
In science and technology students will learn
directly from their environments. Particular
care should be taken to create a physical and
emotional environment that supports the
learning experiences.
When designing the physical aspects of this
learning environment, consideration should
be given to:
• stimulus material
• students’ access to appropriate tools,
  materials, equipment and other resources
• areas in which students can exhibit and
  discuss the development and outcomes of
  their activities
• general attractiveness.
It is particularly important that students have
both the opportunity and resources to explore,
to discover, to manipulate materials and to
use different technologies. In particular
students will need access to a range of computer
and audio-visual hardware and software.
It is also important that teachers create an
emotional environment that is secure, caring
and supportive. In such an environment
students will have confidence to pursue their
own ideas and their contributions to class
activities will be respected and valued.

The units of work included in the support
document are outlines from which teachers
can develop a more comprehensive program.
In some instances only minor additions may
be necessary to make them suitable for
individual classroom environments.
Alternatively, the needs of a particular school
environment may dictate considerable
adaptation of unit outlines before
implementation in individual classes. Factors
such as the developmental stage and previous
experiences of students, the availability of
resources (human and material), the nature of
the learner and the local community will need
to be considered.
It will be necessary to ensure that programs for
a full school year address each of the general
objectives of the syllabus. The sample units of

Task
The task provides a starting point or direction
for each activity. It may be an investigation,
stimulating inquiry and building on the
curiosity of the students, or an open-ended
design brief that sets the parameters or
requirements for designing and making. The
task can be further developed according to
students’ interests, needs or questions.
Investigating tasks provide the context for
the choice and use of technologies to stimulate
and aid inquiry. Designing and making tasks
provide opportunities for many possible
responses that could fulfil the identified
need and incorporate the use of a variety of
technologies.
Activities
These activities rely on the student being
actively involved at each stage of the process
of investigating and designing and making.
Particularly important is the need to value
and encourage students in the areas of
investigating, designing and making and
using technology identified by the students
themselves.
Investigating will often lead to students
designing and making, both as a means of
aiding investigation and in order to
demonstrate and apply their understandings.

Activities
Explore a large variety of natural materials, eg clay, air,
water, wool, rocks, metals, soil, plant materials (wood,
cork). Classify according to shared characteristics, eg
hard/soft, shiny/dull, bends/doesn’t bend, hot/cold. Use a
‘feely’ bag containing objects made from a variety of
materials. Describe as many properties as possible of a
selected item. Predict what the object is and what it’s
made of. Predict the possible effect on materials of hitting
with a hammer, wetting with water, leaving in the sun
etc. Experiment to test the effects. Compare the effects on
different materials. Suggest possible/appropriate uses for
materials based on their characteristics and properties.

Task
Investigate how news is recorded. [W]

Activities
Identify methods of recording news, eg papers, television,
radio. Predict what technology has been used to record the
news items, eg filmed with a video camera, stories written
on a computer, photographs taken with a camera. Identify
features of a news article using a variety of children’s
magazines, eg headline, pictures, captions. In groups,
make illustrations of an item of news and add captions.
Suggest ‘headlines’ for simple items. Illustrate one aspect
of a news item in students’ news stories. Discuss how the
image is a part of the whole item. Add captions to the
pictures. Explore how computer technology can be used to
record and present news. [TS29] Use packages that com-
bine word processing and graphics to experiment with
arrangement of text, headings and graphics in a column
format. [TS38] Print out and compare different layouts.

Do a daily survey. Record results. Make inferences about

go out to eat, eg special occasions, just for fun, when on

Consider all the data about where and when people eat out
and draw conclusions about reasons why.
Explore the ingredients of take–away food. Evaluate their
nutritional value.
Explore the costs of eating out. Prepare a meal similar to
a bought one and calculate the costs involved. Suggest
reasons for any differences between the two.
Consider other advantages/disadvantages, eg saves wash-

• Managing Learning Experiences gives
  teachers suggestions of activities they may

  exhaustive and can be modified and used as
  appropriate and directed to the needs and
  abilities of their particular students.

  issues that may affect students with particular
  needs.

Managing the learning
environment

Purpose of the management strategies
The strategies in this group are designed to assist teachers in their efforts to provide a supportive,
yet challenging science and technology learning environment for their students. They are
strategies which are student-centred and involve teaching practices which benefit all students.
They are also the types of classroom practices which allow the teacher to be not only a facilitator
but also a learner along with his/her students. These strategies can be used either alone, or in
combination, to ensure the aims and objectives of this syllabus are realised by students and
teachers alike.

Managing learning
experiences
To encourage reflecting, the teacher should
pose a question, allow the students to explore
it through introspection, question further and
then discuss.
Opinions can be formed through individual
introspection and/or group consensus.
The students can then be encouraged to express
their conclusions individually either in writing
or verbally.

Aboriginal Students
Aboriginal students may need to be encouraged
to trial and test ideas because they may not be
interested in this strategy to explain things
which are fixed in their culture.
If students are doing this the teacher must
