Module: Chemical Processes
DCI: PS3.D Energy in Chemical Processes and Everyday Life – The
expression “produce energy” typically refers to the conversion of stored energy
into a desired form for practical use.
DCI: ETS1.A Defining Engineering Problems – Possible solutions to a
problem are limited by available materials and resources (constraints). The
success of a designed solution is determined by considering the desired
features of a solution (criteria). Different proposals for solutions can be
compared on the basis of how well each one meets the specified criteria for
success or how well each takes the constraints into account.
PE: 4-PS3-4 Apply scientific ideas to design, test, and refine a
device that converts energy from one form to another.
No Clarification Statements:
The content of this standard seems to be as follows.
- When we say that something "produces energy", we are describing a situation in which the energy stored in something is converted to a useful form.
- The engineering aspect comes in when, it seems, we must concentrate on having kids look at solutions to the problems inherent in converting stored energy to a useful form.
- The context within chemistry leads to the conclusion that the kind of energy conversions we should focus on are those in which humans convert stored chemical energy into useful forms.
