length, mass, time, temperature, volume

What are the five basic measurements that are used for calculation, calibration, and estimation?

*Length    *Mass   *Temperature   *Time    *Volume

SI Units

Standard International unit of measurement used world wide.

SI Unit Symbols

SI Unit instruments

SIUnit usages

Different applications or purpose for each measurement.

The conversions of equivalent measurement units . 

Meniscus

* The curved surface or level of a liquid substance.

Water displacement

*Measurement used to calculate the volume of liquids and volume of irregular shaped solid objects.

*Example: water + rock volume(-) water volume = rock volume

SI Units

length = meters = m, mass  =   kilograms =kg,  temperature = degrees celcius = [image],  time = seconds  = s, and volume = liter = L

triple balance beam measurement

Step 1 - Record weight amounts from large to small.

Step 2  - Line up the decimals and arrange as an addition problem.

Step 3 - Add the three amounts together.

Step 4 - Round the numbers by least significant figures.

Step 5 - Add the measurement units

mass measurement sequence

Line up numbers and decimals and add weights from largest to small. ex  

300.0g

 70.0g

+ 3.4g

               373.4g   = 373g

Density formula

Mass divided by volume  

Density units

 mass (g) /volume (mL)

Meniscus reading

Water displacement formula

water+object volume  (-) water volume = object volume

ex.   9mL     ( -  )          7mL         =         2mL
