Science
Will used a PhET electricity simulation to explore how voltage, current, and resistance relate through Ohm’s law, and how current and voltage behave in series and parallel circuits. He practiced taking circuit readings with ammeters and voltmeters and using those measurements to explain relationships in the circuits. By building circuits from schematic drawings, he connected circuit representations with how components were arranged. He also investigated whether common objects acted as conductors or insulators, linking material properties to the flow of electricity.
Tips
Tips Extend Will’s investigation by having him predict current and voltage readings before changing a circuit, then compare his predictions with the simulation. Invite him to build matching series and parallel circuits and explain how changing one component affects the measurements. He could create a labeled schematic and a short evidence-based explanation of what the ammeter and voltmeter readings show. To connect the simulation to everyday materials, he could make a prediction chart for familiar objects and test them only with a safe, low-voltage classroom circuit under adult supervision.
