Lesson 2 – Design Process-Measuring Wind Speed

This page is currently under construction

Course:  Integrated Science, Physics, Biotechnology and/or STEM courses

Unit:  Measurement, Scientific Process, and Instrumentation Design


Objectives

See Standards Addressed for all NGSS, WA State (Science, Math and Literacy), and NOAA Ocean Literacy Education Standards Connections.  In addition to the aligned objectives linked above, for this lesson, here is a breakdown of:


What Students Learn:

  • Design is an iterative problem solving process.
  • Criteria are standards on which to judge success.
  • Constraints are limitations on possible solutions or problems.
  • Design solutions involve trade-offs.
  • Application should drive criteria for instrumentation design (precision, accuracy, sampling, etc.).


What Students Do:

  • Define criteria & constraints for a wind speed measurement challenge.
  • Brainstorm possible solutions, weigh trade-offs, and carry out proposed methodology.
  • Choose an appropriate number of significant digits to reflect the uncertainty in their data.
  • Evaluate results and suggest improvements.
  • Evaluate their current design’s suitability for a proposed application.
  • Revise design criteria to meet the needs of the proposed application for a measurement.
