The Basic Circuits Kit (SB-CIRCUIT) kit can be used with the Science Fair Project Ideas listed below. Click on any project below to see the full information. Using the tabs on the project, you can view background information and the steps of the experimental procedure.

Which Materials are the Best Conductors?
Science Fair Project Idea
thumbnail Electricity powers many of the devices we use every day, from lights to video games and computers. Engineers have to use certain materials to make electrical devices work. In this experiment, you will find out which materials let electricity flow through them (conductors) and which ones prevent electricity from flowing through them (insulators). Read more

- Less Details
Time Required Very Short (≤ 1 day)
Prerequisites None
Material Availability A kit for this project is available from our partner ….
Cost Low ($20 - $50)
Safety Short circuits can get very hot and present a burn hazard. Never connect the positive and negative ends (red and black wires) of the battery pack directly to each other.
Pencil Resistors
Science Fair Project Idea
thumbnail What do you do with your old wooden pencils when they get too short to hold? Don't throw them away; you can use them to make circuits! This project will show you how to use pencils to make resistors, an important part of many electrical circuits, and test how they affect the brightness of a lightbulb in a simple circuit. Read more

Safety Short circuits can get very hot and present a burn hazard. Never connect the positive and negative ends (red and black wires) of the battery pack directly to each other. Adult supervision is required for cutting the pencils.
How to Make a Dimmer Switch with a Pencil
Science Fair Project Idea
thumbnail Dimmer switches let us control the brightness of a light, anywhere from completely off to full brightness. This can be nice when you want to set the brightness "just right," as opposed to a regular light switch that only lets you turn a light on or off. It turns out that you can make a dimmer switch out of an everyday object—a pencil! Try this project to find out how a dimmer switch can control the brightness of a light. Read more
