Assessment guide
How to read student work on this assessment — standards alignment, what strong understanding looks like, and common gaps.
Learning progression
Target understanding
9.B Optimize performance of a design that represents systems and energy flows between systems by revising and retesting to incorporate characteristics of the most promising solutions.
Standards alignment
9.B Optimize performance of a design that represents systems and energy flows between systems by revising and retesting to incorporate characteristics of the most promising solutions.
What understanding looks like
Strong
- As teams reflect on their work in Lesson 9 to complete Engineering Design Rubric, make sure students are referring to their optimal design and the associated test results recorded on Design Testing Matrix in their science notebooks. At this point in the unit, this rubric rating can be considered a summative assessment, as students have had more experience with engineering design in this lesson and previous lessons.

9.A Communicate technical information in writing about how to transfer energy through a system that was designed to perform better than any of its predecessors by using parts of different solutions.
What to look / listen for
and listen for
Teams’ how-to homemade heater instructions that are intended for stakeholder-users should be clear and easy to follow and should include, but are not limited to, the following items listed on How-To Instructions Must-Haves: amounts of reactants, types of materials to be used, and how to vent the gases.
What to do
If a team’s how-to instructions do not include the items listed above, remind the team to go back and add those. If a team is struggling to write clear instructions, suggest that they number their instructions, think about instructions they have used before, and address the sticky-note feedback they received on the first iteration of their How-to Instructions Must-Haves in Lesson 7. If a team is still struggling, have them watch how-to videos as an example of helpful instructions. Once you approve the teams’ instructions, place your initials on How-To Instructions Must-Haves to indicate what parts you have approved.
