Summary
Students are introduced to circuits through a teacher demonstration using a set of Christmas lights. Then student groups build simple circuits using batteries, wires and light bulbs. They examine how electricity is conducted through a light bulb using a battery as a power source. Students also observe the differences between series and parallel circuits by building each type.Engineering Connection
This introduction to circuits also serves as an introduction to electrical engineering since every electrical device has a circuits designed by electrical engineers.
Learning Objectives
After this activity, students should be able to distinguish the difference between a parallel circuit and a series circuit.
Educational Standards
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.

| Define a simple design problem that can be solved through the development of an object, tool, process, or system and includes several criteria for success and constraints on materials, time, or cost. Alignment agreement: | Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account. Alignment agreement: | People's needs and wants change over time, as do their demands for new and improved technologies. Alignment agreement: |

Materials List
- 1 set of Christmas lights (a string of lights)
- 1 alkaline lantern battery per group, 6 volt size
- 6 alligator clips or wires
- 2 to 3 light bulbs per group, whatever size fits into the light bulb holder
- 1 light bulb holder per light bulb; available at electronics stores or online at www.hometrainingtools.com
Introduction/Motivation
Plug the string of lights into an electrical outlet and explain how electrical current flows through the circuit to make the lights work. Refer to the associated lesson for background information to help with this.
Have students each take out a light bulb from the string of lights to see how current flows to the light bulb through the metal wires on the side of the light.
Procedure
Screw the light bulbs into the light bulb holders.
Build a simple circuit using one battery, two alligator clips, and a light bulb.
- Attach one end of an alligator clip to the positive terminal of a battery.
- Then, take the other end of the clip and attach it to one side of the light bulb holder's conducting material (typically this is another piece of metal).
- Take another alligator clip and attach one end to the other side of the light bulb holder's conducting material.
- Finally, attach the free end of the second alligator clip to the negative terminal of the battery to complete the circuit.
Now using the diagram below as a guide, build a series circuit.
Now, using the diagram below, try to build a parallel circuit.
Vocabulary/Definitions
circuit: A path through which electrical current can flow.
circuit diagram : An illustrative picture used to explain the paths through which electricity can flow.
conductor: A material that allows for electrical current to flow.
current: The flow of electrons through a condutor.
electricity: A source of power generated from the flow of electrical current.
electron: A small, atomic particle with a negative charge.
energy : The ability to do work.
Assessment
Descriptions: Have students briefly describe the differences between parallel and series circuits.
Drawings: Have students draw simple sketches of parallel and series circuits.
Investigating Questions
- What would happen if the battery were turned around in the circuit? Explain your answer.
- Which would be brighter—light bulbs in series or light bulbs in parallel? Why?
- Let students re-examine the string of lights. What happens when you remove certain light bulbs along the string of lights? What do you see, in terms of circuit type?
- When buying Christmas lights, what kind of lights would be the best to buy in terms of circuit setup?
Safety Issues
Make sure the Christmas lights are not plugged into an outlet while students are trying to remove the bulbs from the circuit.
Troubleshooting Tips
Make sure the batteries are new.
Make sure that no lights are broken.
Make sure that all the wires are securely attached to each connection point to avoid gaps in the connections (short circuits).
Activity Scaling
For students who have a good understanding of how to build circuits, have them build combination series and parallel circuits.
