Science Department


To nurture creative, innovative and independent learners for the new economy.


An inquiring Crescentian and an innovative Department.


By the end of Secondary 4, a Crescentian should be able to:

  1. acquire sufficient  understanding and knowledge to become confident citizens in a technological world;
  2. develop an informed interest in matters of scientific importance;
  3. recognise the usefulness and limitations of scientific methods and models and to appreciate their applicability in everyday life;
  4. possess abilities and skills that
  • are relevant to the study and practice of science,
  • are useful in everyday life,
  • encourage efficient and safe practice, and
  • encourage effective communication;
  1. possess attitudes relevant to science such as accuracy and precision, objectivity, integrity, inquiry, initiative and inventiveness.

Special Programmes

Inquiry is incorporated into our science curriculum to enable students to view the pursuit of science as meaningful and useful, and also to develop 21st century competencies in our students. Some of our innovative curricula include our ‘Physics By Inquiry’, ‘Flipped Classroom in Chemistry’ and ‘Integrated Curriculum’.

Physics By Inquiry (PBI)

In PBI classes, students work in groups to carry out certain activities and worksheets are provided to guide them through the inquiry journey. Students will firstly predict the results of the activity before discussing within their groups and explain to one another how they arrive at their own predictions. The group will then carry out the experiment and note down their observations. If the observations match their predictions, they are sure that they are on the right track and could proceed with the next activity. If the observations do not match their prediction, this will provide the opportunity for the groups to discuss the concepts involved, their assumptions and their analysis of variables in the experiment. Through the discussions, students refined their mental models and aligned it with the observations. At the end of each section, students are to come up with the concepts and relationship on their own.

Flipped Classroom in Chemistry

This flipped classroom pedagogical model, anchored by the BSCS 5E Instructional Model and the three Principals of Learning, is used to design lesson activities to explicitly develop 21st century competencies such as knowledge building, collaboration, real-world problem solving and innovation in students. During lessons, activities are designed to allow students to experience 3 stages of inquiry, namely: Dissonance (Stage 1), Discovery (Stage 2) and Discourse (Stage 3), to develop scientific understandings and apply them to their coursework.

Integrated Curriculum (IC)

Our Secondary 1 Science and Secondary 3 Biology are involved in the Secondary 1 IC and Secondary 3 IC respectively. Through the Integrated Curriculum, students are able to apply what they have learnt from the various subjects to solve a common problem in the real world context. The IC programs also help the students to see the links between the various subjects.

The Science department also provides co-curricular programmes that complement our core science curriculum to generate further interest in science learning. These programmes include ‘Pet Rocket’, ‘Innovation and Creativity’ and ‘Life Science’ workshop. For students who have a keen interest in the areas of science, they can also take part in the Science Mentorship Program and the Talent Development Program.

Pet Rocket

The PET Rocket programme aims to excite the students about application of science concepts through a hand-on approach using a PET rocket. The PET rocket is propelled by pressurised water within the PET bottle that is used to construct the rocket. The students collaborate in pairs in building a PET rocket under the guidance of a trainer. With a brief theory lesson on Newton’s Laws, Principle of Conservation of Energy and aerodynamics, the students construct a PET rocket through their creativity in applying the science concepts.  The programme allows students to put in their critical thinking and problem solving skills when they construct and test their rockets. The process also helps the students to build effective collaborative and communication skills.  

Innovation and Creativity workshop

This workshop is aimed at developing students’ creative thinking, critical thinking, and problem solving skills. It is constructivist in nature, in which students are engaged in solving relevant, authentic and real world problems, and they will be guided to draw their own conclusions and learn to apply their knowledge in a different context.  In the process, they will also be able to reinforce their content knowledge and further strengthen their understanding. They will be challenged to look at things differently and create models in an open-ended process that will demonstrate change, improvement or provide beneficial solutions to everyday problems. The spirit of determination, perseverance and learning from failures that is an integral part of innovation will also be incorporated. At the end of the workshop, students will work in groups to come up with a project proposal based on the theme assigned to them. Students’ 21st century skill will be assessed from this project.

Life Science Workshop

This workshop introduces the students to the current advances in life sciences with emphasis in the applications of DNA fingerprinting and recombinant DNA technology.  Students also learnt about the principle of restriction enzyme and agarose gel electrophoresis. Some interesting hands-on activities include students extracting their own DNA from their cheek and students playing the role of detectives to analyse various pieces of evidence found in a crime scene to solve the crime.

Science Mentorship Programme

Students who express a keen interest in the area of science research can participate in the Science Mentorship Program. Through mentorship attachment, students will have the opportunities to deepen their knowledge in a particular area, to learn about the latest research developments and to be challenged by the intellectually stimulating process of scientific research. At the end of their attachment, students will also be able to share and present their research findings in the Youth Science Conference.

Secondary 3 Science Talent Development Programme

Students in Science Talent Development Programme will have the opportunity to learn beyond the scope of the O-Level Sciences. Through this programme, students will gain an insight into one of the most important industries in the world, which is the perfumes and cosmetics industry. They will be able to see the integration of Biology, Chemistry and Physics in creating products for the consumers. They will also get a chance to do experiential learning by creating some of these products on their own!
