As ZIS we offer a valuable chemistry education which is taught in an exceptional environment. As we know, chemistry is not a subject that can only be taught in the classroom, there must also be laboratory activities which foster interest and learning among the students.  All these facilities are in place here at Zaman.

Chemistry may be greeted with avid interest, disinterest, or even antipathy by students. Whether students will be caught up in the excitement of chemical demonstrations and laboratory experiments, or experience difficulties learning topics like atomic structure, the ‘mole concept’, and organic chemistry, is definitely important both for them as individuals and also to society in general. Many significant, beneficial discoveries are a result of chemical research; from the discovery of elements to recent mass spectrometric studies. Chemistry teachers have to prepare students for examinations by creating effective learning environments and utilizing practices that address the ‘affective aspect’ of student learning (e.g. self-confidence, responsibility, respect, dependability, and personal relations). By doing this we can fully engage students and maintain interest and excitement while learning chemistry.

Although our curriculum is a typical examination-focused one, the pedagogical strategies employed both in and out of school can be uniquely interwoven with informal learning experiences for students, thus narrowing the cognitive and affective gap. In the long term, this may help in building a community that appreciates, or at least understands, the effect chemistry has on our daily lives.

In grades 7, 8, and 9, students have 2 sessions of chemistry per week. We teach chemistry 3 sessions a week for grades 10, 11, and 12.

Students learn the answers to the following questions during the course:

  • What is classification?
  • How do we describe the properties of materials?
  • How do we choose suitable materials for different uses?
  • What are the basic ‘building blocks’ of matter?
  • How can elements be classified?
  • How can we distinguish among elements, compounds and mixtures?
  • What are separation techniques?
  • What are some applications of separation techniques in everyday life?
  • How can we obtain pure water from seawater?
  • How can we distinguish between solutes, solvents and solutions?
  • What are some uses of solvents and solutions in homes and industries?
  • What are the factors that affect solubility and the rate of dissolving of substances?
  • What is the nature of common acids and alkalis?
  • What are the effects of acidic, alkaline, and neutral solutions on indicators?
  • What are the effects on a ‘universal indicator’ when acidic and alkaline solutions are mixed?
  • How can we classify the changes around us?
  • What chemical and physical changes does matter undergo?
  • How can we make use of these changes and benefit from them?
  • Why do solids, liquids and gases have different physical properties?
  • How do smells travel?
  • How can we explain melting, freezing, boiling and condensation?
  • What is matter made up of?
  • What are the characteristics and structure of an atom?
  • How is an ion formed?
  • How can we identify the types of atoms in a compound?

Students do many experiments which help lead them to recognize and discover the laws of chemistry.

Students prepare drama shows, presentations, and information cards to help them to master the lessons and believe in themselves. They watch many videos about chemistry during the term.

Worksheets and many kinds of puzzles are given to them to review their lessons and for making lessons enjoyable.

Chemistry teachers have to prepare the students for the following year’s curriculum and examinations.

We present some of the lessons if time permits, which means when the teacher has time and the year has gone well.  Even though not in the Cambodian curriculum, extra subjects are presented to the students in order for them to comprehend chemistry well.
