Pearson Saskatchewan Science 9 is custom published for Saskatchewan and developed by a team of Saskatchewan teachers. At the beginning of each unit, the "Big Ideas" box sets the focus for the unit. A Big Idea then provides the title for each section in the unit. Throughout the unit, opportunities are provided for students to work together, communicate ideas, perform experiments and carry out library and Internet research. Key vocabulary is bolded throughout the unit and an explanation of each term is provided. All key terms and explanations are also listed in a glossary at the back of the book. First Nations and Métis content, perspectives, and ways of knowing are an integral part of the Saskatchewan science textbook. Highlights of the activities and achievements of Saskatchewan men and women are provided in the "Ask an Elder," "Ask an Expert," and "Careers and Profiles" features. In each unit, the "Ask an Elder" feature provides access to the wisdom of a First Nations or Métis Elder or Traditional Knowledge Keeper, who shares an oral story related to the content of that unit.
