Unit 2: Measurement

Suppose you get an e-mail from a friend who lives in Canada. Your friend complains that it has been too hot lately to play soccer or ride a bike. The high temperature each day has been about 35. You think that this figure must be wrong because a temperature of 35 is cold, not hot. Actually, 35 can be either hot or cold depending on which temperature units are used. For a measurement to be useful, it must include both a number and a unit.

Why is this important to use? What do planting a garden, painting a room, and planning a party have in common? For each task, you need to gather and analyze data.

In this unit, you will:

ª Recognize SI units of measurements.

ª Convert data into scientific notation and from one unit to another.

ª Round off answers to the correct degree of certainty.

ª Use graphs to organize data.
