1 Monday, August 29, 2016 Your Learning Goal: After students learn how to accurately read a ruler, they will use a ruler to correctly measure and build a Metricopter. Table of Contents: Rules of the Ruler - 3R Catalyst: (3L) Why is it important for everyone to read a ruler the same way? It is important for everyone to read a ruler the same way because. Homework: Observation and Inference DUE FRIDAY Agenda: 1. Pre-write 2. Notes: How to Read a Ruler 3. Reflection 4. Metricopter!!!!

3 8/29/16 Catalyst: It is important for everyone to read a ruler the same way because. 8/29/16 Rules of the Ruler 3L 3R

4 Big Question: How do all scientists communicate with each other?

5 How to be

6 So what happens when we don t make accurate observations or communicate clearly?

7 Why are measurements important? *Measurements are important because " " " 1) They give us a way to " " " communicate clearly " " " using a common system. 3R

9 Why use a ruler? 2) A ruler is used to measure length or distance. How long is this fish? 3R

11 Using a Ruler A ruler has two sets of marks CENTIMETERS INCHES

14 * Using a Ruler The long lines with numbers are centimeters (cm). The shorter lines are millimeters (mm). 10 mm = 1 cm The half-way lines are a little longer (every 0.5 cm or 5 mm). Millimeter (shorter line) Centimeter (numbered line) 3R

15 *Steps for Measuring in cm: #1: Line up the zero mark on the ruler with the edge of the object you are measuring. #2: Record the whole centimeter, followed by a decimal point. 4. #3: Record the number of millimeters. #4: Write down the units. 4.2 cm 4.2 4R

17 Ruler Practice Centimeters

18 8/29/16 Catalyst: It is important for everyone to read a ruler the same way because. Reflection: Measure 3 found objects from around the room and record your measurements here. (Make sure to write your measurements in both mm and cm). 8/29/16 Rules of the Ruler Measurements are important because 1) They give us a way to communicate clearly using a common system. 2) A ruler is used to measure length or distance. A ruler has two sets of marks Inches and centimeters. *Steps for measuring in centimeters: #1: Line up the zero mark on the ruler with the edge of the object you are measuring. #2: Record the whole centimeter, followed by a decimal point #3: Record the number of millimeters #4: Write down your units 3L 3R

19 Each person is going to make their own paper Metricopter on lined paper. Your challenge is to make sure you re using the ruler correctly. When each member of your team is done, you can race your Metricopter. The person with the slowest Metricopter is the winner.
