1. Design Attributes- 3.4.10.C1- Apply the components of the technological design process.
2. Engineering Design- 3.4.10.C2- Analyze a prototype and / or create a working model to test a design concept by making actual observations and necessary adjustments.
2. Engineering Design- 3.4.12.C2- Apply the concept that engineering design is influenced by personal characteristics, such as creativity, resourcefulness, and the ability to visualize and think abstractly.
3. Research and development, Invention and Innovation, Experimentation/Problem solving and Troubleshooting 3.4.10.C3- Illustrate the concept that not all problems are technological and not every problem can be solved using technology.
3. Research and development, Invention and Innovation, Experimentation/Problem solving and Troubleshooting 3.4.12.C3- Apply the concept that many technological problems require a multi- disciplinary approach.
