What is the mass shown on the balance below? Tuesday, August 21Warm-Up A: 501 grams
MYP Unit Question:Why Science? Area of Interaction:Approaches to Learning Learner Profile:Inquirer Standard:Use tools and instruments for observing, measuring and manipulating equipment and materials in scientific activities. Learning Target:Today I’m learning about metric units because I will use them for scientific investigations
Opening: Intro to Metrics Work Session: Notes: Metric System Measurement Activity
Why use the Systeme International (SI)? It’s a standard system of measurement that allows scientists to compare data and communicate with other scientists all over the world.
Scientists all over the world use the International System of Units to measure: • Length • Volume • Mass • Density • Temperature • Time
The basic unit of length in the SI system is the … meter M D D H C K M Meter 1 Deka- Deci- 10 .01 Hecto- Centi- 100 .001 Kilo- Milli- 1000 .0001 King Henry Died Monday Drinking Chocolate Milk
Use the stair step to convert Example: 10 K = ? M 10 K = 10,000 M Determine the direction to move Count the number of steps Add “0” for every step you move 3 M D D H C K M Meter 1 Deka- Deci- 10 .01 Hecto- Centi- 100 .001 Kilo- Milli- 1000 .0001 King Henry Died Monday Drinking Chocolate Milk
3 = .1 100 mm = ? M 24 cm = ?hm 4 = .01 M D D H C K M Meter 1 Deka- Deci- 10 .01 Hecto- Centi- 100 .001 Kilo- Milli- 1000 .0001 King Henry Died Monday Drinking Chocolate Milk
How to read a metric ruler The longer lines on the metric ruler are called… • centimeters
