What paths can electricity take ? Outcomes 302-23 ,207-2 construct simple circuits, safety and compare static and current electricity
Electricity only flows through certain material • It will only flow if it has somewhere to go. When a current travels through a wire, the wire is part of a circuit . If the circuit is broken, what happens. • Try this interactive: • http://www.engineeringinteract.org/resources/siliconspies/flash/concepts/simplecircuits.htm
Are all circuits the same ? • What is a parallel circuit ? • http://scifiles.larc.nasa.gov/text/kids/Problem_Board/problems/electricity/circuits2.html • Take this quiz • http://myschoolhouse.com/courses/O/1/68.asp • So far we have created simple circuits. Today will look at series and parallel circuits. • Read the first paragraph on this link • http://epb.apogee.net/foe/fcsps.asp

Now turn to page 20 and 21 in your student book • Read the instructions carefully. • Check your work station and make sure every thing you need is there. • Work through the experiment.
Done the lab ? • Clean up • On a piece of loose leaf, using HP format, answer the following questions. • 1) draw and label your parallel circuit. • 2) what is the difference between a series circuit and a parallel circuit ? • 3)What is the symbol for switch ? Draw it.(hint page 22) • Read page 20. If done write a paragraph about fuses.
