What we will do What we will learn 10CSC1 18 Haratua 2015 Preliminaries and roll How to start well Visit switches What a switch does Introduce the idea of conductors and insulators What conductors and insulators are Make a circuit to test things and then make a summary What things are conductors and insulators Revisit functions of equipment What they actually do Build a circuit from a description How to read instructions for circuits If time, set some more Scipad pages and look ahead to Mrs Drysdale’s lesson tomorrow What is coming up

HW item Skills practiced Scipad pages 125 - 143 Due already DNA and genetics Scipad pages 10, 11, 12, 14 Due Wed 25 Mar 2015 Atoms and atomic structure

Build circuits from descriptions

Build circuits from descriptions Build a series circuit with a power supply, two lamps and one switch. After you have built it, draw the circuit diagram

Build circuits from descriptions Build a series circuit with a power supply, two lamps and one switch. After you have built it, draw the circuit diagram Build a parallel circuit with a power supply, one lamp and one switch in one of the two branches. In the other branch put two lamps. After you have built it, draw the circuit diagram
