Answer a question or test a hypothesis.

Example:

You are given a machined element made of material A that needs to

operate in a certain wide temperature range.

What to pay attention to: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Question: Does the material A expand as temperature increases?

Hypothesis: Material A expands as temperature increases

Experiment design$/$plan:

$1.$ What to measure: Machine element length$($L$),$ Temperature$($T$)$

$2.$ How to measure:

a$.$ T: $\_\_\_\_\_,\_\_\_\_\_\_\_\_,\_\_\_\_\_\_$

b$.$ L: $\_\_\_\_\_,\_\_\_\_\_\_\_\_,\_\_\_\_\_\_$

$3.$ Procedure:

a$.$ Change $\_\_\_.$

b$.$ Measure $\_\_$ and $\_\_$

$4.$ Design and build a setup

$5.$ Perform measurements

$6.$ Analyze results

$\_\_\_\_\_\_\_\_\_\_\_,\_\_\_\_\_\_\_\_\_\_\_\_,\_\_\_\_\_\_\_\_\_\_\_\_\_$

$7.$ Study sources of error, perform uncertainty analysis $($can be

initiated at the design stage $-$ step $2-4$ or before$).$

$8.$ Write a report
