Pearson Saskatchewan Science 4. Student Edition
Pearson Saskatchewan Science 4 is custom published for Saskatchewan and developed by a team of Saskatchewan teachers. Each unit starts with a list of "Big Ideas" that set 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 text. First Nations and Métis content, perspectives and ways of knowing are an integral part of the Saskatchewan science text. Highlights of the activities and achievements of Saskatchewan men and women are provided in the "Ask..." feature. In each unit, the Ask... 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.
