Series and Parallel Circuits Activity
Curriculum Big Idea: Energy can be transferred between objects and/or can be converted into different forms. Concept: Electricity is the result of converting one form of energy into another and the flow of electrons via a conductor. PA Standard 3.2.P.B4: Explain how stationary and moving particles result in electricity and magnetism. Develop qualitative and quantitative understanding of current, voltage, resistance, and the connections among them. Explain how electrical induction is applied in technology. 3.2.P.B4: Explain how stationary and moving particles result in electricity and magnetism.

Today’s Agenda Opener: Answer the “What Do You Think?” Questions in the Series and Parallel Circuits Activity (see handout). Discuss in small groups and as a class. For You To Do: Investigate series and parallel circuits using an online lab simulation and real life circuits. Circuit Online Lab Simulation Circuit Online Lab Simulation Discuss series and parallel circuits. Write a reflection on the activity. Closure: Is a home wired in series or in parallel? Explain your answer. Take Home Assignment: page 560 #6-8
Reflection Questions (answer in complete sentences) 1. Draw a schematic diagram of two batteries in series, two light bulbs in series, one switch, and one ammeter. 2. In the circuit above, how does the total voltage gain of the batteries compare to the total voltage loss of the light bulbs? 3. Draw a schematic diagram of two batteries in series, two light bulbs in parallel, one switch to control both light bulbs and one ammeter to measure the current through the batteries. 4. In the circuit for #3, how does the voltage gain of the batteries compare to the voltage loss of each branch in the parallel circuit? 5. In which circuit are the bulbs more bright? 6. Which circuit has the greater current?
