SCIENCE CURRICULUM RESOURCES OVERVIEW FOR GRADE 11A Sem 2- SCHOOL NAME: Science Curriculum Resources Overview* – GRADE 11A – SEMESTER 2 Strand Total Curriculum Standards (based on CORE STANDARDS in Scheme of Work (Semesters 1 & 2) Curriculum Standards for Semester 2(Based on 80 53 Chemestry Enquiry Standards % (Based on Curriculum standards) Covered in text books 19 100% scheme of work) Please Note:* Inquiry Standards are an integral part of science teaching – every effort must be made in providing opportunities for pupils to practice these skills. AT THE END OF EACH UNIT BELOW THERE IS A SPACE FOR THE SCIENCE DEPT TO OUTLINE HOW THEY INTEND TO DO THIS. Text book references are given to help teachers teach, and also provide a reference for pupils. However this does not replace the good practice of teachers using a variety of resources to teach and explain further in order to cover the curriculum standard fully.
