Core Skills Analysis
Science
Will attended a circuitry class and programmed circuits to behave in a predictable pattern. Through this activity, he explored how electrical components can be organized and controlled to produce repeatable outcomes. He practiced scientific and engineering thinking by connecting a programmed system’s inputs, processes, and outputs. The activity also introduced systems-based problem solving, including observing circuit behavior and considering how programming affects the circuit’s function.
Tips
Tips: Help Will extend this learning by having him diagram the circuit and label its power source, conductive paths, components, and programmed behavior. He could create a simple prediction chart showing what the circuit should do under different conditions, then test and record the results. Invite him to modify one element at a time and explain how the change affected the pattern, reinforcing fair testing and cause-and-effect reasoning. A short presentation or written explanation of his circuit’s design would also build technical communication skills.

Learning Standards
- Virginia Science SOL 4.2: Will’s circuitry work connects to energy being used to perform work and to electrical circuits, while his programming explored how a system’s behavior can be controlled and repeated.
- Virginia Science SOL 1.1: Although written for Grade 1, the activity reflects the practice of asking questions, observing system behavior, using tools, and defining or solving an engineering problem.
- Virginia Science SOL 1.2: The programmed circuit’s predictable pattern provides a connection to investigating how objects or systems can operate and change in response to controlled inputs.
