PREAMBLE
This Lower Secondary Science Normal (Technical) Syllabuscovers the first two-years of a four-year syllabus designed toprovide secondary school students in the Normal (Technical)Course with the necessary foundation in science for post-secondary technical courses.
This syllabus is also a further development of the Primary
Science Syllabus. Based on the notion of a spiral curriculum,fundamental concepts introduced at the primary school level arebuilt upon and treated in greater depth at the lower secondarylevel. The content knowledge and the learning approach of thissubject consolidate and build on what the student has acquiredthrough science in the primary school. A student who hascompleted primary school education in any of the streams will beadequately prepared to study this subject.
This syllabus is based on the Science Curriculum Frameworkandemphasises the need for a balance between the acquisitionof science knowledge, skills and attitudes. In addition, theknowledge and skills to be acquired in this subject have directrelevance to technical courses. Many of these skills and muchof this knowledge are in the physical sciences. Topics which are
aimed at developing an interest in and a positive appreciation ofscience and technology have also been included. In addition,some topics on the human body and healthy lifestyles havebeen included to prepare the students for adult life.
The aims spelt out in the syllabus provide the guiding principlesfor the suggested teaching approaches and evaluation methods.
Teachers are advised not to follow the syllabus too rigidly but toexercise their professional judgement in implementing it.Schemes of work should be developed with the interests andabilities of the students uppermost in mind. Teachers are
encouraged to use a variety of approaches in their teaching andto incorporate ideas and materials from various sources, in orderto enhance the learning of science.

SCIENCE CURRICULUM FRAMEWORK
The Science Curriculum Framework is derived from the PolicyFramework for the Teaching and Learning of Science. Itencapsulates the thrust of science education in Singapore toprepare our students to be sufficiently adept as effectivecitizens, able to function in and contribute to an increasinglytechnologically-driven world.
Central to the curriculum framework is the inculcation of thespirit of scientific inquiry. The conduct of inquiry is founded onthree integral domains of (a) Knowledge, Understanding andApplication, (b) Skills and Processes and (c) Ethics andAttitudes. These domains are essential to the practice ofscience. The curriculum design seeks to enable students toview the pursuit of science as meaningful and useful. Inquiry is
thus grounded in knowledge, issues and questions that relate tothe roles played by science in daily life, society and theenvironment.

The science curriculum seeks to nurture the student as aninquirer. The starting point is that children are curious about and
want to explore the things around them. The science curriculumleverages on and seeks to fuel this spirit of curiosity. The endgoal is students who enjoy science and value science as animportant tool in helping them explore their natural and physicalworld.
The teacher is the leader of inquiry in the science classroom.Teachers of science impart the excitement and value of scienceto their students. They are facilitators and role models of theinquiry process in the classrooms. The teacher creates alearning environment that will encourage and challenge studentsto develop their sense of inquiry. Teaching and learningapproaches centre around the student as an inquirer.
The following table shows the description of each domain which
frames the practice of science:

B Skills and Processes
In this syllabus, teachers are encouraged to provideopportunities for students to use concepts and integrateskills and processes to inquire about science aroundthem.
Skills
Using apparatus and equipmentThis is the skill of knowing the functions and limitations ofvarious equipment and apparatus, and being able toselect and handle them appropriately for various tasks.
Posing questionsThis is the skill involving the clarification of issues andmeaning through inquiry. Good questions focus attentionon important information and are designed to generatenew information.
ObservingThis is the skill of using our senses to gather qualitativeas well as quantitative information about a particularobject, event or phenomenon. This also includes the use
of instruments to extend the range of our senses.
ClassifyingThis is the skill of grouping objects or events according tocommon attributes or properties.
ComparingThis is the skill of identifying the similarities and
differences between or among objects or entities.
CommunicatingThis is the skill of transmitting and receiving informationpresented in various forms - verbal, tabular, graphical orpictorial.
InferringThis is the skill of interpreting and explainingobservations, data or information gathered.
Formulating hypothesisThis is the skill of making a general explanation for arelated set of observations or events. It is an extension ofinferring.
PredictingThis is the skill of assessing the likelihood of an outcomebased on prior knowledge of how things usually turn out.
AnalysingThis is the skill of clarifying information by examiningparts and relationships contained in the information.
ElaboratingThis is the skill of providing details, examples and otherrelevant information so as to make ones ideas morecomprehensible to others.

VerifyingThis is the skill of confirming or proving the truth of an
idea, using specific standards or criteria of evaluation.
Generating possibilitiesThis is the skill of exploring all the alternatives,possibilities and choices beyond the obvious or preferredone.
Defining the problemThis is the skill where one makes conscious effort toclarify situations that are puzzling in some way. Theextent, scope and nature of the problem are identifiedand clarified.
Processes
Processes are complex operations which call upon theuse of several skills.
Planning InvestigationThis process involves formulating questions orhypotheses for investigating and devising ways to findanswers. It also involves deciding on the type ofequipment required, and measurements to be made, aswell as identifying the variables involved and manipulatingthe variables so that the effect of only one variable can beobserved in any one experiment.
Creative problem solvingThis is the process of thinking through a problem andchoosing an innovative solution that meets the
requirements. This thinking process is used wheneverone faces obstacles and wishes to overcome them so as
to arrive at a practical and workable solution.
It must be pointed out that there is also no one definitesequence of priority among the skills and processes listedabove. For example, observation may lead tohypothesising but at other times a hypothesis can lead toobservation. All the skills and processes listed above areseen as part of the total process of scientific inquiry.
In science teaching and learning, effort should initially bedirected at teaching explicitly each of the skills throughthe use of appropriate activities. Later, effort should bedirected to helping students integrate some or all of theskills in scientific inquiry.
C Ethics and Attitudes
In scientific inquiry, the adoption of certain mentalattitudes such as curiosity, creativity, objectivity, integrity,open-mindedness, perseverance and responsibility isadvocated. Attempts should also be made to promotesafety consciousness among students and to encouragestudents to adopt safe practices.
CuriosityThis is the attitude of desiring to explore the environmentand question what they find.
7/30/2019 Science Lower Secondary Nt 2008

CreativityThis is the attitude of seeking innovative and relevant
ways to solve problems.
ObjectivityThis is the attitude of seeking data and information tovalidate observations and explanations objectively.
IntegrityThis is the attitude of handling and communicating dataand information with integrity.
Open-mindednessThis is the attitude of accepting all knowledge as tentativeand the willingness to change our views if the evidence isconvincing.
PerseveranceThis is the attitude of pursuing a problem until asatisfactory solution is found.
ResponsibilityThis is the attitude of showing care and concern for livingthings and awareness of our responsibility for thesustainability of the environment.
Opportunities should be provided in the classroom forstudents to ask questions. Students should beencouraged to ask both closed and open questions.From the type of questions asked by the students,teachers could gather information on their frame of mindand the quality of their understanding.

ASSESSING TEACHING AND LEARNING
Assessment is an integral part of the teaching and learningprocess. It involves gathering information through variousassessment techniques and making sound decisions.Assessment provides information to the teacher aboutstudents achievement in relation to the learning objectives.With this information, the teacher makes informed decisions
about what should be done to improve teaching methods andenhance the learning of the students.
Why Assess?
Assessment measures the extent to which desiredknowledge, skills and attitudes are attained by students.While it complements the teaching and learning process, it
also provides formative and summative feedback to teachers,students, schools and parents.
Assessment provides feedback to students, allowsthem to understand their strengths and weaknesses.Through assessment, students can monitor their ownperformance and progress. It also points them in the
direction they should go to improve further.
Assessment provides feedback to teachers, enablesthem to understand the strengths and weaknesses oftheir students. It provides information about studentsachievement of learning outcomes as well as theeffectiveness of their teaching.
Assessment provides feedback to schools. The
information gathered facilitates the placement ofstudents in the appropriate stream or course, and thepromotion of students from one level to the next. Italso allows the schools to review the effectiveness oftheir instructional programme.
Assessment provides feedback to parents, allows themto monitor their childrens progress and achievementthrough the information obtained.
What to Assess?
The aims of the Lower Secondary Science Normal(Technical) Syllabus deal with the acquisition of knowledge,understanding and application of the science concepts, the
ability to use process skills, and the development of attitudesimportant to the practice of science. The assessmentobjectives of the syllabus are aligned to the three domains inthe Science Curriculum Frameworkas shown below:
i. Assessment of Knowledge, Understanding andApplication of Science Concepts
ii. Assessment of Skills and Processiii. Assessment of Ethics and Attitudes

How to Assess?
Assessment measures the extent to which desiredknowledge, skills and attitudes are attained by students. As itserves many purposes, it is important to match the type ofassessment to the specific purpose for which it is intended.Before making an assessment about a certain aspect ofstudents performance, the teacher should ensure that theassessment mode used will generate information that reflect
accurately the particular aspect of performance the teacherintends to assess.
In an inquiry-based classroom, the assessment can takemany forms. In addition to the written tests, teachers canalso conduct performance based assessment using thefollowing modes:
Practicals Projects Teacher observations Checklists Reflections / Journals Model-making Posters Games and quizzes Debates Drama / Show and Tell Learning Trails
Teachers can also assess students through the use ofportfolio. It is a systematic collection of students work andprovides a comprehensive picture of their achievement. Thework collected provides a continuous record of the studentsdevelopment and progress in the acquisition of knowledge,understanding of scientific concepts, application of processskills, and development of attitudes. It also provides
opportunity for the students to have self-evaluation andreflections by revisiting their own portfolio.
The assessment modes listed above are by no meansexhaustive. Adopting a variety of assessment modes enablesthe teachers to assess different aspects of teaching andlearning.
Guidelines for Assessment
It is essential for assessment to be aligned to the teachingand learning process. School-based assessment, bothformative and summative in nature, should be used to providea complete picture of the students performance andprogress, and the effectiveness of the teaching and learning
process.

CORE UNIT 4:INVESTIGATINGFORCES Force Machines
OVERVIEWIn this unit, students learn about forces and their effects. There are manyforces acting around us. (Forces are generally classified as a push or apull; some common forces around us are gravitational, frictional andmagnetic forces.) Forces are needed for objects to start moving and stopmoving, to move faster or slower, and to change the direction of motion.We cannot see forces but we can see and feel the effects of forces.
Students then increase their understanding of forces by studying simplemachines. Emphasis is placed on investigating a variety of simplemachines and recognising that simple machines are examples oftechnologies that help humans make work easier, thereby developingpositive attitudes towards technology uses that increase productivity.

CORE UNIT 6:INVESTIGATING HEAT Temperature
andthermometer
Heating andcooling matter
OVERVIEWHeat is very important to life. Heat is a form of energy. When energytransformation takes place, it usually involves the gain or loss of heat. Infact, other forms of energy can be converted into heat energy.
Interactions between energy and matter account for changes observed ineveryday events. Understanding how heat energy and matter interact
helps students understand a wide variety of physical changes.
KEY INQUIRY QUESTIONS What is temperature and
how is it measured? How does heat change
matter?
