Building towards
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.
