You must estimate analog measurements, the kind you will make here. Digital measurements only require reading a number.
Some analog measurements are listed below.
Length: meter stick
Mass: triple-beam balance
Force: spring scale
Volume: graduated cylinder
In this lab, you'll measure distance, mass, temperature, force, and volume.
Any measurement consists of two parts:
the value and
If you report a length as being 1.7, no one will know whether it's the size of a bacterium or a continent. Don't leave out the units.
Accuracy tells how good your measuring device is.
Does it measure correctly?
Precision is all about repeating measurements and getting the same value.
Try to measure the height of someone who won't stand still.
