Module 1

Module 1: The International System of Units (SI)

 

Lesson Summary

 

Bison ranches are becoming more common across the Prairies. Ranchers need to determine how many animals the area they have for pasture can sustain. If you were a rancher, you would apply the skills you mastered in this lesson to manage your grazing land and your livestock.

 

In this lesson, you explored these questions.

• How is area—the amount of surface—measured in SI?

• What are the common units used when measuring area in SI?

• How are areas in one unit converted to another unit?

To answer these questions, you examined the relationships among the square metre, square centimetre, square millimetre, square kilometre, and hectare. You discovered these relationships are based on powers of 10. To convert among these units, you just had to move the decimal to the left or right.

Unit Project

 

Before you move on to the next lesson, you should complete the scale diagram of your Unit 1 Project. Please note that when you complete your work later in this unit, you will be asked (at a later time) to indicate measurements using both SI and imperial units. Identify an area in your Unit 1 Project now that you will later convert to imperial measure. For more information about this and later steps in the Unit 1 Project, refer to the Unit 1 Project.
