Students are introduced to the concept of electricity through hands-on investigation of how circuits work. Students will construct a simple circuit and record their experiences in their science journal. Note: Circuit kits (one per individual/group) will need to be prepared ahead of time. Kits are to include 1 C-cell battery, 2 insulated copper wires, 1 battery holder, 2 brass battery clips, 1 small flashlight bulb, and 1 socket.

Working as if they are engineers who work for (the hypothetical) Build-a-Toy Workshop company, students apply their imaginations and the engineering design process to design and build prototype toys with moving parts. They set up electric circuits using batteries, wire and motors. They create plans for project material expenses to meet a budget.

We are surrounded everyday by circuits that utilize "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are made of many simpler parallel and series circuits. In this hands-on activity, students build parallel circuits, exploring how they function and their unique features.

Everyday we are surrounded by circuits that use "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are composed of many simpler parallel and series circuits. During this activity, students build a simple series circuit and discover the properties associated with series circuits.

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the current, I, for each set resistance value, students plot the three points on a Cartesian plane and note the line that is formed. They also see the direct correlation between the amount of current flowing through the lamp and its brightness.

In this lesson, students will investigate energy, electricity, and circuits by creating an emergency flashlight using common everyday materials. Then they will work collaboratively to design a model subdivision, creating a simple circuit to provide light to the "buildings" in their model.

In this activity, students will organize electricity-related vocabulary words into a web or cluster design.

Students use a simple circuit to learn how conductors allow electricity to flow and how insulators do not allow electricity to flow.

In this activity, students build and experiment with electric circuits using easily available materials. Students are challenged to find three pathways that successfully complete the circuit, and three pathways that do not successfully complete the circuit. Students will sketch the pathways in their journals, and compare and contrast their drawings with peers.

In this activity students will first brainstorm all the terms (vocabulary) they can think of related to electricity. Next, they will work collaboratively in groups to try to define these terms. Then in groups they will create word webs drawing correlations between the various terms. Groups will discuss how light bulbs work, how they light up, write down their ideas. Next, students will try to draw what they believe a circuit is and how it works. They will need to write several sentences concerning their thoughts. Then they will be given a battery, wires and a light bulb and asked to check their designs. Students will explore what they believe series and parallel circuits are, write down their ideas and draw some pictures. They then will be given materials to try and create these circuits. Finally, students will predict and test differences in bulb brightness in a variety of series and parallel circuits.

During a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever noticed that for the flashlight to work you must orient the batteries a certain way as you insert them into the casing? Many people do not know that a flashlight is a simple series circuit. In this hands-on activity, students build this everyday household item and design their own operating series circuit flashlights.

Students explore the composition and practical application of parallel circuitry, compared to series circuitry. Students design and build parallel circuits and investigate their characteristics, and apply Ohm's law.

Students learn that charge movement through a circuit depends on the resistance and arrangement of the circuit components. In a hands-on activity, students build and investigate the characteristics of series circuits. In another activity, students design and build a flashlight.

 Background:  students are familiar with static electricity, charge, and sparks.  They also know about conservation of energy, forms of energy including potential energy, power, and work.  Students will complete a variety of activities using breadboards, which will display various types of circuits and their effect on the flow of electricity.

Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.

Students build their own two-cell batteries. They also determine which electrolyte solution is best suited for making batteries.
