Student Sheet 

Teacher Answers 

Estimated class Time:

One 40-minute class period


How did our prototype perform?


  • Criteria and constraints list
  • Thermometers
  • Heat packs
  • Same data chart as test day 1

Lesson Level Learning Objectives:

  • MS-ETS1-2:  Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.


  • Test the prototypes. Compare initial test data to final test data.
  • Complete the written reflection.


What we Figured Out: 

  • Students learn how well they met the criteria and constraints.

Questions we still have:

  • My prototype still didn’t meet all of the criteria and constraints, how can I make it better?
  • How are the working incubators different than mine?
  • Can I reflect on this unit to better explain how my incubator works?
