Presentation Transcript

  1. 11/4/13 switches and circuits • Science podcast: Rat Casinos • Bulb brightness • PhET circuit activity • Switches • House wiring • Homework: Combination Circuits worksheet, read associated material.

  2. Learning objectives • Describe how the brightness of bulbs changes in series and parallel circuits when a bulb is added or taken away. • Use Ohm’s law and the power relationships to solve for an unknown • Construct a simple switch and a three-way switch.

  3. Practical difference between series and parallel circuits Go over series and parallel worksheets

  4. Rate the bulbs from brightest to dimmest A D B E C F

  5. PhET Circuits activity (http://goo.gl/uYiX) Discuss activity and worksheets

  6. Simple switches Do the switch activity at your table

  7. Planning your house • With your house wiring group, design a plan for a room with a single switch controlling a light. • Design a plan for a single switch that controls two things with one being on at a time or both off. • Design a plan for an object that’s controlled by two switches such as a living room light that can be turned on and off from the front door or the kitchen. This is called a 3-way or double switch on the assignment sheet. • You should be able to power the object by moving only one switch or the other no matter the position of the 2nd switch. These switches must be apart from each other. • Test these out with your materials and using the PhET circuits simulation found at http://goo.gl/uYiX . • Share with the class.
