PETALING JAYA: Deputy Prime Minister Tan Sri Muhyiddin Yassin will announce soon the mechanism for changeover to the teaching of Science and Mathematics in Bahasa Malaysia.

This is to ensure the smooth implementation of the revised policy, Deputy Education Minister Datuk Dr Wee Ka Siong said.

"What is important now is to prepare for the soft-landing approach so that students who had studied the subjects in English would not be affected by the change", he said after presenting prizes to student athletes at the MSSM-Milo Sports Awards ceremony here yesterday.

Muhyiddin, who is also Education Minister, had said Science and Mathematics would continue to be taught in both English and Malay up to 2015, when the final batch of students involved in the learning of Science and Mathematics in English (PPSMI) programme had completed their secondary education.

The PPSMI was implemented in phases from 2003, beginning with Year One, Form One and Lower Six students.

In 2009, Muhyiddin announced that the Government would revert to teaching the subjects in Bahasa Malaysia in national schools as well as Chinese and Tamil in vernacular schools.

Dr Wee said parents and groups who had lobbied for Science and Mathematics to be taught in English had the right to voice their views, adding that there were also groups which had opposing views.

"If the Cabinet does not change the decision made in 2009, the policy to revert to Malay in national schools and Chinese and Tamil in vernacular schools, will be carried out next year", Dr Wee said.

[Science Form 4] Energy Conversion

Question:

How is electrical energy generated from nuclear energy?


Answer:
  • Nuclear energy is produced in a nuclear reactor.

  • The resultant heat energy is used to boil water.

  • Steam from the water rotates the turbines.

  • The turbine rotates and moves the dynamo.

  • The electricity generated is then directed to cables to be transmitted.

[Physics Form 5] Cathode Rays


Question:
How are cathode rays formed?

Answer:
  • The 6V source first heats up the filament, which, in turn, heats up the cathode.

  • The cathode thus exhibits thermionic emission and produces thermal electrons.

  • The EHT exerts a strong electric field between the cathode and the anode, causing the thermal electrons to accelerate, and travel at a high speed and in a straight line towards the anode.

  • The beam of fast-moving electrons generated is known as cathode rays.
