The document describes the parts of an electrical circuit including a battery, wires, and a light bulb. It instructs students to connect the parts in different configurations to see if the bulb lights up. When all parts are correctly connected from the negative terminal of the battery to the positive terminal, forming a complete loop or path, the bulb will light up. If any part is missing, the circuit is broken and energy cannot flow to power the bulb.

1. Parts of a CircuitBrett Belcher

2. Standard Indicator ProjectStandard 4.6.1-Common ThemesDemonstrate that an object consisting of many parts, the parts usually influence or interact with one another.

3. Background InformationAn electrical circuit is a path which electrons from a voltage or current source follow.Electric current flows in a path called an electric circuit.Without each part of the circuit working together, energy will not be transferred.

4. VocabularyCircuit - an electrical device that provides a path for electrical current to flowCurrent – a flow of electricity though a conductorEnergy – the capacity of a system to do work.

5. MaterialsFor this project the materials you have been provided with are:D- cell batteryFlashlight bulbsWireTapePaper and Pencils

6. ActivityFor your first try, use wire to connect one end of your wire to the negative (bottom) part of the battery. Use the other end of the battery and connect it to the base of the bulb.Does the bulb light up?______________

7. ActivityFor your second try, use one end of the wire and connect it to the positive (top) end of your battery. Use the other end of the wire and connect it to the base of your bulb.Did the bulb light up?____________

8. ActivityFor your third attempt, use wire to connect the negative (bottom) part of the battery to the base of the bulb. With another strand of wire connect the positive (top) part of your battery with the base of the bulb.Did the bulb light up?__________

9. AssessmentOn the paper provided to you answer the following questions.What happens when all of the parts of the circuit are used?What happens when only some of the parts of the object are used?Why do you think everything has to be connected for the bulb to light up?
