This educational module explores the metric system, covering its history, fundamentals, and applications. Students will learn to convert between metric units, such as centimeters to meters, and apply these conversions to solve multi-step, real-world problems. The course compares the metric and customary measurement systems and investigates key concepts like volume, weight vs. mass, and water displacement. Engaging video clips and interactive games reinforce learning and help students grasp the practical importance of the metric system in everyday life.

The Metric System A Global Way to Measure
COMMON CORE STANDARDS • 6.MD.1. Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.
Objectives • Students will be able to: • Describe a brief history of the metric system • Identify units in the metric system • Convert units within the metric system • Compare and Contrast the metric system and the customary system of measurement
Measurement Measurement can answer many kinds of questions. For example: • How far? • How much? • How fast? • What temperature? • What time? • How high? • How deep? And many more…
Metric Video • Everyday Measurements • Brief History of the Metric System
What was early measurement based upon? • Parts of peoples bodies. • Such as finger, hand, arm, foot, etc. How is this a problem? People are different sizes, so the measurements could be different.
They chose the parts of one persons body for measurement. Whoever was the current ruler of the kingdom. • How was the problem fixed? • How was this a problem? The rulers changed over time and the measurements with them.
How was this problem fixed? They stopped changing it whenever a new king or queen came into power.
The Metric System • Why the metric system? It is a scientific system that is standard all over the world. Except one place… USA

The Metric System • The metric system is based on the power of 10. BASE milli centi deci deca hecto kilo Meter x10 x100 x1000 1/1000 1/100 1/10 Liter Gram
What is Volume? • The amount of space a substance occupies as measured in liters. What is used to measure liquid volume? • A graduated cylinder. Volume of objects can also be measured by multiplying the length X width X height.
Video Clip • Measuring volume • Measuring Mass
Water Displacement • Water displacement is a way to measure the volume of an irregular object. • This works because an object will displace an amount of water equal to its volume when it is submerged.
Weight vs. Mass • Weight -is the effect of gravity on an object. • Mass -is the measure of the amount of matter in an object. • Mass is measured in grams. Often measured with a balance.
Video Clips • Weight vs. Mass • Converting Metric Units • Volume
Length • Length- the distance between two points • Length in the Metric System is measured in meters.
