  1. Prototype Design Charlie Haffey Norwood Elementary Science

  2. Scientific Experiment Pre 2001 Science Standards NSC – grades 3 & 4 today Universal applications

  3. Scientific Experiment Independent Variable One thing changed between 2 groups Dependent Variable Measured Result Controls All other things constant

  4. Engineering Design Process AKA Prototype Design Build a model (prototype) Identify an improvement Rebuild model with improvement Physics specific

  5. Steps of the • Engineering Design • Process

  6. Iterative Design Repetition testing, analyzing, and refining Keep solutions simple Cheaper Smallest number of things going wrong Easier to “fix” a problem Add complexity later
