This resource has students performing an inquiry lab to design a parallel electrical circuit to keep bulbs lit even when one in another branch is removed (burns out). The activity requires students to draw their circuits and to keep making changes, if needed, until they are successful. Then they have to write a report discussing their work and also detailing how energy flows through the circuit and gets the bulbs to light up.
The resource has detailed instructions and support for both instructors and students. The resource was intended for 4th grade, but with the elements of the NGSS that are selected below, and coupled with the suggestions provided, it is actually well suited for a regular level high school physics course if the teacher skips Activity 1 and instead uses Activities 2 and 3: circuit analysis of a string of lights in series, and design of a circuit which will light the string even when one bulb is removed.
