2022/2023 SS2 Chemistry Scheme Of Work

Chemistry scheme of work

This is to notify our reader that The ss2 chemistry scheme of work (senior secondary school two) for this session is now available on our website for free especially for chemistry teachers and students in senior secondary in Nigeria. As we all know that chemistry is a one of the pure science subject offered in only secondary throughout Nigeria. Therefore this post imply chemistry teachers about the government approved chemistry scheme of work for ss2 which include first term, second term and third term.

Learning should be from known to unknown, easier to complex, the riders therefore this chemistry scheme of work for SS 2 first term, is the continuation of the third term chemistry scheme of work for ss1. As part of our practice the scheme of work provided here is arranged systematically for better understand for both ss2 teacher and student.

With the mandate from the ministry of education, it is willful that all private and public senior secondary schools in Nigeria should use the same scheme of work. In order to be in line with the desires of all external exam bodies such as WAEC and NECO, the ministry of education compulsory it that schools should should submit government approved scheme of work for all  subject offered as one of the prerequisite requirements for approving the operation or license to run a secondary school in Nigeria.

The principals and teachers in secondary schools in Nigeria are to embrace to the appropriate approved scheme of work as ordered by the ministry of education because the approved scheme of work for Chemistry (Senior secondary school two) is the same for both private and public

From our observations the approved scheme of work for Chemistry in Senior secondary school two (SS 2) from first term to third term is the same irrespective of whether the school is a public or private, so for this reason the search for the government approved scheme of work for Chemistry in senior secondary school level has been on higher demand by chemistry teacher throughout the federation, the reason is that chemistry is a compulsory science subject offered for all student in science department as it is important requirements for admission and for candidates who wants to study Chemistry, health science, engineering, science and any science related course in higher institutions.

This post is mostly important for ss2 science students because the provided scheme here detailed the current Chemistry scheme of work it vividly analysis and emphasize on 1st term, 2nd term and 3rd term), which also comprises of the government approved scheme of work for all topics and sub-topics, teacher and students activities and behavioural objective.
