1. Measurement in Metrics AC Science

2. Metric System Systems Internationale Systems Internationale AKA “SI” AKA “SI” Based on factors of 10 Based on factors of 10

3. LENGTH Length: distance between 2 points, measured in meters. Symbol for unit: m. Length: distance between 2 points, measured in meters. Symbol for unit: m. Tool: meter stick or metric ruler Tool: meter stick or metric ruler

4. MASS Mass: amount of space an object takes up, measured in grams. Symbol for unit: g. Mass: amount of space an object takes up, measured in grams. Symbol for unit: g. Tools: triple beam balance (or electronic scale), or spring scale Tools: triple beam balance (or electronic scale), or spring scale

5. AREA Area: length times width, symbol for unit: cm 2 Area: length times width, symbol for unit: cm 2 Tool: meter stick Tool: meter stick

6. TEMPERATURE Temperature: measure of heat in an object Temperature: measure of heat in an object American Standard – unit is Fahrenheit. Symbol for unit: 0 F. (Degrees Fahrenheit) American Standard – unit is Fahrenheit. Symbol for unit: 0 F. (Degrees Fahrenheit) Metric Scale– unit is Celsius. Symbol for unit: 0 C. (Degrees Celsius or Centigrade) Metric Scale– unit is Celsius. Symbol for unit: 0 C. (Degrees Celsius or Centigrade) Metric Scale – unit is Kelvin. Symbol for unit: K. (Kelvin). ** ONLY used when discussing ABSOLUTE ZERO!! Metric Scale – unit is Kelvin. Symbol for unit: K. (Kelvin). ** ONLY used when discussing ABSOLUTE ZERO!! Tool: thermometer Tool: thermometer

7. VOLUME Volume: amount of matter an object contains, unit is liter. Volume: amount of matter an object contains, unit is liter. Symbol for unit: L (if the object is a liquid or irregular solid) - normally we use milliliters (ml). Use displacement method for irregular solids! Symbol for unit: L (if the object is a liquid or irregular solid) - normally we use milliliters (ml). Use displacement method for irregular solids! OR cm 3 (if the object is a regular solid). Volume = length times width times height for a regular solid. OR cm 3 (if the object is a regular solid). Volume = length times width times height for a regular solid. Tools: meter stick (for regular solid) Tools: meter stick (for regular solid) beaker or graduated cylinder for liquid beaker or graduated cylinder for liquid Graduated cylinder and water for irregular – displacement method Graduated cylinder and water for irregular – displacement method

8. DENSITY Density: the amount of matter in a given amount of space Density: the amount of matter in a given amount of space Density = mass divided by volume. D = m/v Density = mass divided by volume. D = m/v Measured in g/cm 3 (if the object is a solid) Measured in g/cm 3 (if the object is a solid) OR g/ml (if the object is a liquid or an irregular solid)…. OR g/ml (if the object is a liquid or an irregular solid)…. Tools: balance or scale for finding mass Tools: balance or scale for finding mass Beaker or graduated cylinder for finding volume of liquid Beaker or graduated cylinder for finding volume of liquid Graduated cylinder and water for finding volume of irregular solid (displacement method) Graduated cylinder and water for finding volume of irregular solid (displacement method)
