Engineering

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Describe how internal and external parts of computing devices function to form a system.
Model how computer hardware and software work together as a system to accomplish tasks.
Determine potential solutions to solve simple hardware and software problems using common troubleshooting strategies.

Compare and refine multiple algorithms for the same task and determine which is the most appropriate.
Create programs that use variables to store and modify data.
Create programs that include sequences, events, loops, and conditionals.
Decompose (break down) problems into smaller, manageable subproblems to facilitate the program development process.
Modify, remix, or incorporate portions of an existing program into one’s own work, to develop something new or add more advanced features.
Test and debug (identify and fix errors) a program or algorithm to ensure it runs as intended.
