Woodlands Secondary SCIENCE SNC1D Student Exploration: Circuits Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary​:​ ammeter, circuit, current, electron, ohmmeter, Ohm’s law, parallel circuit, resistance, resistor, series circuit, voltage Prior Knowledge Questions ​(Do these BEFORE using the Gizmo.) Strings of holiday lights can be designed in one of two ways. In some strings of lights, each light is connected to the others along a single wire (in series). In others, each light is attached to its own wire (in parallel). 1. Suppose a single light bulb burns out. How do you think this will affect lights that are strung along a single wire? 2. How will a single burned-out bulb affect the string of lights if each light is attached to its own wire? Gizmo Warm-up The ​Circuits ​Gizmo shows a circuit board and a variety of components. Create a ​circuit with a battery, a light switch, a wire, and a light bulb, as shown. (Click the light switch to turn it to ​OFF​.) 1. Click the light switch to turn it to ​ON​. What happens? 2. Turn on ​Show current​ and select ​Electron flow​. The moving dots represent a ​current​ of ​electrons​—tiny, negatively charged particles—moving through the wire. ​Voltage​ ​is a measure of how much more potential energy an electron at one end of a battery has than an electron at the other end of the battery.

There will be no change in the brightness of the other lights. This is an example of a parallel circuit The light turns on A. How does changing the battery’s voltage affect the current? It changes the amount of power, meaning it can be brighter B. How does changing the battery’s voltage affect the brightness of the light? The higher voltage, the brighter the light will be 3. Remove the wire. What happens? The light turns off
