Dashed lines representing edges not visible from the current perspective. Construction Lines: Light lines used for alignment.

Activity 1.2.3 is a key hands-on exercise in the PLTW curriculum, typically found in or Introduction to Engineering Design (IED) . This activity bridges theoretical engineering concepts with practical circuit design and measurement. Students learn to construct, analyze, and troubleshoot basic electrical circuits, reinforcing Ohm’s Law, series/parallel configurations, and multimeter usage. 1.2.3 pltw

In the curriculum, "1.2.3" refers to a specific foundational activity found across several major courses, including Introduction to Engineering Design (IED) , Principles of Engineering (POE) , and Computer Science Essentials (CSE) . While the subject matter varies by course, each "1.2.3" activity serves as a bridge between theoretical knowledge and practical application. 1.
