A piece of iron heated at one end slowly warms at the other end. The rate of heat conduction determines how quickly the far end becomes hot. The term for rate of heat conduction is thermal conductivity.
In this lab, you determine how fast various materials conduct heat. The end of the rod is put in heated water (about 71°C). A liquid crystal strip tracks the rise of temperature along the rod. The liquid crystal changes color as the temperature changes.
The neck's calibrations show 0.1 ml per large calibration mark and 10 microliters (μl) for the smaller marks. Microliters are 1,000 times smaller than milliliters.Some analog measurements are listed below.

Length: meter stick
Mass: triple-beam balance
Force: spring scale
Temperature: thermometer
Volume: graduated cylinder
In this lab, you'll measure distance, mass, temperature, force, and volume.
Measurement

Any measurement consists of two parts:
the value and
the units.

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
Accuracy tells how good your measuring device is.
Does it measure correctly?

Precision
Precision is all about repeating measurements and getting the same value.
Try to measure the height of someone who won't stand still.
