Document Content and Description Below

Name: ______________________________________ Date: ________________________ Student Exploration: Circuit Builder Vocabulary: circuit, closed circuit, conductor, current, electron, fuse, insulator, o ... pen circuit, parallel circuit, series circuit, short circuit Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What do a light bulb, a toaster, a radio, and a computer all have in common? They all have electrical currents. 2. Suppose you connect a battery to a small light bulb with a single wire. What do you think will happen? Explain your answer. Nothing Gizmo Warm-up: Build a circuit 1. Using the Standard components in the upper left of the Gizmo™, try to get a light bulb to light up. You can drag as many bulbs, wires, batteries, switches and fuses as you like onto the circuit board. A circuit is a path containing easily moveable charges. When the light bulb lights up, negatively-charged particles called electrons are flowing through the wire and bulb. This flow is called current. 2. Now try to light the bulb with the smallest number of components. Make a sketch of your simple circuit in this space: 3. Based on what you have seen, what must be true for a circuit to light a bulb? You need the switch a light bulb wire and a battery and a fuse. https://www.coursehero.com/file/30890986/CircuitBuilderSEdoc/ This study resource was shared via CourseHero.comActivity A: Closing a circuit Get the Gizmo ready:  Click Clear.  Turn on Show current and select Electron flow.  Set up components as shown to the right. Introduction: You should have just built an open circuit (shown above). The gap on the left prevents the flow of charges. There are no gaps in a closed circuit, so charges can flow. Question: What materials will close a circuit? 1. Predict: Conductors are materials with easily movable charges, allowing current to occur. Insulators do not have easily movable charges, so current is not produced. Look at the nine Materials at lower left. Which do you think are conductors? Which are insulators? A. Predicted conductors: lead plastic yarn B. Predicted insulators: glass iron silver wood brass copper C. How could you use your open circuit to test if a material is a conductor or insulator? Fill in the whole 2. Experiment: Drag each material into the gap of the ope [Show More]
