Measurement and Units

1. Measurement and Units

2. Measurements and Units How old are you? How tall are you? The answers to these questions are Measurements. Measurements are important in both science and everyday life. Hardly a day passes without the need for you to measure amounts of money or the passage of time. For a measurement to make sense, it requires both a number and a unit. For example, if someone tells you the store is “five” from the school, you would probably ask, “Five what? Five meters? Five blocks?” You typically describe a distance using standard units of measurement, such as meters, miles, or kilometers. By using units, you help other people understand exactly what your measurement mean. In your daily conversations with your peers and family, you use measurements to convey what you want them to understand. Measurements are distance, time, volume, density, mass, temperature, area, speed, acceleration, force, weight, electric current, energy, and etc. Units help you describe measurements. They make understanding measurements easy. Many of the units you are familiar with, such as inches, feet, and degrees Fahrenheit, are not units that are used in science. Scientists use a set of measuring units called SI, or the International System of Units. SI units started in France 1791. SI units include meter (m), gram (g), Kelvin (K), centimeter cube (cm3), and gram per centimeter cube (g/cm3). Analysis Questions • What is the main idea of the passage? • Give five examples of measurements? • Give five examples of units? • What does SI stand for and who uses SI units?

Green Liquid Count the number of heartbeats within the following times provided. a. 30 seconds b. 45 seconds c. 60 seconds (Analysis Questions) • What is the main idea of the lab? • What measurement does cm measure? • What measurement does mL measure? • You can use a ruler to measure? • You can use a graduated cylinder to measure? • You can use a thermometer to measure?

6. Distance Volume Temperature Area Mass Density Cheatsheet Half your paper the long way. Fold the Paper from the bottom to the middle. Fold the Paper from the top to the middle.

7. 2.35cm a. Practice Problems: Directions: Identify the images using the following terms-Mass, Distance, Volume (l), and Temperature. b. c. d.

8. Practice Problem Directions: Write the measurement and give the correct unit using your cheat sheet notes. Measurement Unit Distance meter Temperature Volume (liquid) Volume (solid) Mass Area Density

9. Measurements: Units • Units have PREFIXES attached to them PrefixSymbolMeaning Kilo (k) 1000 Hecto (h) 100 Deka (da) 10 Unit Deci (d) 0.1 Centi (c) 0.01 Milli (m) 0.001

10. Prefix Line

11. Practice ProblemsDirections: Write the name of the units with the correct prefix and name the correct measurement. cm=centimeter=distance 9. hg= m= 10. dm= mm= 11. daL= g= 12. K= kg= L= mL= cm3

12. Practice ProblemsDirections: Write the name the correct measurement. 1.02mm=distance 9. 0.5m2= 8.02m= 10. 0.2cm= 9.03mL= 11. 100g= 10cm3= 12. 101.2cL= 0.05hm= 10,000kg= 80L= 8K=

13. Lab Equipment Worksheets Directions: Copy the following Worksheets. Make sure to title each worksheet. Measuring Liquids Measuring The Temperature Balance Ruler

14. Measurement Review Lab Group in Pairs of 2. There are 4 parts to the lab. Go to the assigned station to complete the lab. Make sure to title your lab.

15. Construct Graduated Cylinder and Thermometer Look over and Read the Worksheets before you start to cut. You will have to cut and fold along the lines to make the Graduated Cylinder and Thermometer. You will Color your Graduated Cylinder and Thermometer.

16. Measurement and Units Test Directions: Read the passage and answer the questions. YOU DO NOT NEED TO WRITE THE QUESTIONS. Measurements and Units How old are you? How tall are you?
