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.
