Title Discovering patterns of current and voltage in series and parallel circuits
Description In this guided lab activity, students measure voltage and current in different designs of circuit. Students decide what to measure in order to generate their own rules to describe how current and voltage behave in different circuits. Students also make predictions about the brightness of light bulbs in different circuits, based on the rules they created.
