Basic Science Skills (BSS)
Introduction
Science is a way of learning about the natural world. Science is a process; hence
emphasis of teaching science should be placed on methodology. The process of teaching and
learning science should be carried in the climate that allows hands-on student activities which
involve inquiry process and scientific method. In inquiry-based classrooms, students are
provided with hands-on opportunities and are more actively involved and subsequently more
responsible for their learning. This is in line with the most important ideas that come from
Piaget’s work that children at this Formal Operational stage of cognitive development need
concrete, hands-on experiences. At this stage science lesson is activity – based experience.
Children also need to be able to share their experience with others and to consider other
viewpoints so that they can move beyond themselves.
During the first three months transition period of secondary education, students should be
allowed to develop skills in handling laboratory apparatus/instruments, carrying out experiments
and be exposed with learning experiences that require less guidance and fewer teacher
interventions in the next stage of their learning.
BSS is designed to develop students who are competent in both science knowledge
and manipulative skill. This module provides lesson plans, worksheets and suggestions as a
guide to implement the teaching and learning of BSS program.
BSS focuses on developing skills in handling basic science apparatus, developing science
process skills and to instill enthusiasm and positive attitudes in learning science. The teaching
and learning process in this programme should enable students to acquire knowledge, master
basic science process skills and develop scientific attitudes in an integrated manner. Teaching
and learning approaches will be implemented through various methods such as experiments,
discussions, simulations, small projects, and field trips. It is hope that the use of hands-on
activities can result in substantial improvements in science process skills and creativity, increase
performance on language development and improve attitudes towards science.

BASIC SCIENCE SKILLS : STUDENTS MODULE
Student’s achievement in this program is assessed through several evaluative tools. A pre
test is carried out before class begins. The pre test is a hands–on test which is based on student’s
knowledge and skills acquired in their primary school. A survey on student’s attitude towards
learning science is also conducted. Continual monitoring of students progress during
implementation of the module is done by teacher’s observation of students while they engage in
their science investigations. A formative test is administered in the middle of the module to
provide feedback for teachers about students’ understanding. Students are also assessed on their
project work and laboratory report. A post test at the end of the module is administered to
evaluate the students’ knowledge and skills. The post test consists of two parts. The first part is a
hands-on practical test based on the manipulative and science process skills they have learned in
the module. The second part is a written test which consists of objective and structured questions
based on the content area covered in the module.
Objectives
1. To develop the skill of knowing the functions and limitations of various instruments /
apparatus, and being able to select and handle them appropriately for various tasks.
2. To develop positive attitudes towards learning science like having interest and enjoyment
in learning science, disposition to try and innovate and attempt creative solutions,
disposition not to jump to conclusions, and willingness to have their own ideas
questioned.
3. To develop the basic science process skills such as making hypothesis, determining
variables, taking measurements, making observation, sort and classify, compare and
contrast, record, analyse and communicate experimental findings.

4. To fulfill the objectives of School Based Assessment (SBA) , which are:
I. To enhance the meaningfulness of assessment where the focus is more on
pupils’ development and growth in learning rather than merely on their
achievements in the form of scores or grades;
II. To reduce the over-reliance and over-dependence on data (grades and scores)
obtained through central examinations in getting information about pupils in
the school system;
III. To empower the school and teachers to conduct quality assessment of and for
learning, involving their own pupils. Therefore school assessment will be
given its due recognition and acknowledgement, and a significant place in the
overall assessment system; and,
IV. To ensure the performance of pupils is comparable to accepted world
standards in various areas of knowledge, skills, and competence, with the
introduction of Standard-Referenced assessment in PBS.

Using a Burette
A) Cleaning a Burette
1. Pour about 10 ml water into the burette using a small beaker.
2. Use a filter funnel at the top of the burette to avoid spills when pouring the water
from the beaker.
3. Allow a few drops of the water to flow through the tip by opening the stopcock.
4. Then remove the burette from the clamp and rotate horizontally so that the entire
interior surface of the burette has been rinsed with the water.
5. Dispense the water through the tip of the burette.
6. Repeat step 1-5 using the required solution.
B) Remove air bubbles
1. Clamp the burette to the retort stand.
2. Fill in the burette with solution by using a small beaker. Allow the solution to drain
so that it is beneath the calibrated markings on the side of the burette.
3. Check the tip of the burette to make sure there is no air bubble.
4. You may need to tap the burette to remove the bubbles.
5. If a drop hangs on the end of the burette before you make your initial reading,
dislodge it by touching it to a beaker.
C) Filling the burette
Fill in the burette with liquid.
1. Take an initial reading of the burette at the correct eye position to the meniscus.
2. Read to the appropriate number of significant digits.
3. Dispense the appropriate volume and take a new reading.
4. Then, empty the burette.
5. Rinse the burette with distilled water several times by following the methods in
(A).
6. Store upside down on the retort stand using the burette clamp.
CAUTION:
In many experiments you will have to dispose of a liquid chemical at the end of a lab. Always
ask your teacher for the correct method of disposal. In many instances, liquid chemicals can be
washed down the sink’s drain by diluting them with plenty of tap water. Toxic chemicals should
be handled only by your teacher.

3. You are required to carry out the following activities in the stations stated.
4. Repeat the activities at each station for three times and record your measurement
readings in Table 6.1. Your answer must be written with the correct decimal place.
Station Activity Measuring 1 Reading Average
Apparatus 23
1 High of laboratory table Ruler
2 Length of laboratory Measuring tape

CONCLUSION
1. We should be taken the readings for ________________ times to obtain __________
data.
2. The eye of student/observer should be ________________ to the scale of measuring
tools.
3. For the measuring cylinder and thermometer, the position of eye should be at the same

ACTIVITY 3: INSTRUCTIONS FOR THE GAME OF THE DARTS:
1. Students are to form groups of 4.
2. Each member of the group is given a dart each.
3. Each member of the group take turn to throw the dart to the target. The idea of the
game is to get the best target, that is the middle of the target.
4. .After all the groups have completed the game, each group must analyze their
performance and determine which throw is most accurate, which throw is least
accurate, whose throws are most consistent.
5. Fill in the table ‘high’ or ‘low’ to indicate accuracy and consistency of the shot in the
different groups.
