1. The Metric System A Global Way to Measure

2. 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.

3. 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

4. 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…

5. Metric Video • Everyday Measurements • Brief History of the Metric System

6. 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.

7. 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.

8. How was this problem fixed? They stopped changing it whenever a new king or queen came into power.

9. The Metric System • Why the metric system? It is a scientific system that is standard all over the world. Except one place… USA

10. Metric Video Clip • The Metric System

11. 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

12. Common Abbreviations

13. 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.

14. Video Clip • Measuring volume • Measuring Mass

15. 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.

16. 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.

17. Video Clips • Weight vs. Mass • Converting Metric Units • Volume

18. Length • Length- the distance between two points • Length in the Metric System is measured in meters.
