Using the State Curriculum: Science, Grade 4

Clarifications: Each clarification provides an explanation of an indicator/objective to help teachers better understand the skills and/or concepts.

Standard 5.0 Physics

Topic C. Electricity and Magnetism

Indicator 2. Investigate and provide evidence that electricity requires a closed loop in order to produce measurable effects.

Objective c. Describe and compare the path of electricity (circuit) within this system that caused the light to light or the buzzer to sound to those that do not affect the light or buzzer.

Clarification
The electricity flows from the battery to the wire to the light bulb and then returns to the battery which lights the light bulb. A closed circuit is formed when all parts are properly connected. A closed circuit is necessary for electricity to flow. If the wire or the bulb is not properly connected to the battery, electricity will not flow and the bulb will not light.
