Aim: How can the metric system help us make uniform

measurements?

Do Now: The smart board needs a new cover. What can we use to measure the smart board

with if we don’t have a tool?

Why do we measure?

• We cannot rely on observations made with only our senses. They aren’t accurate.

• Measurements help us gather information. • Exact measurements are important to

scientists.

How do we measure?

Customary• Difficult to convert

between measurements.

• What we use in the US. • Examples include:

inches, feet, quart, gallon, ounces, pounds.

Metric• Easy to convert

between measurements.

• Used by scientists and most of the world.

• Examples include: meters, liters, and grams.

How do we measure?

• Scientists use the metric system to make measurements. This system is based on the idea that measurements can easily be converted because it is based on the number 10.
