Name: Date: Introduction to Circuits PhET Lab Part 1: Light a Bulb Vocabulary: circuit, closed circuit, conductor, current, electron, fuse, insulator, open circuit, parallel circuit, series circuit, short circuit Prior Knowledge Questions (Do these BEFORE using the PhET.) 1. What do a light bulb, a toaster, a radio, and a computer all have in common? 2. Suppose you connect a battery to a small light bulb with a single wire. What do you think will happe Explain your answer. Part 1: Can you light the bulb? A circuit is a path containing easily moveable charges. When the light bulb lights up, negatively-char particles called electrons are flowing through the wire and bulb. This flow is called current Go to https://phet.colorado.edu/sims/html/circuit-construction-kit-dc/latest/circuit-construction-kit- dc en.html to complete this inquiry lab. 1. Click on Intro (Light bulb Icon to enter the PhET. 2. Click and drag 1 wire, 1 battery, and 1 light bulb to the work area. 3. Click and drag a battery, one light bulb, and one wire to the blue work area. a. Find a way to connect these items so that the light bulb lights. NOTE: Connecting on the opposite terminal of the battery is not considered a "different" arrangement. b. Sketch 2 different arrangements that work and 2 arrangements that do not work. Arrangements that light the bulb Arrangements that do NOT light the bulb 1. 2. 1. 2. your prediction 4. Based on what you have seen, what must be true for a circuit to light a bulb
