 Lesson Plan - Making a Circuit for the Lighthouse LessonFocus:      Identify common appliances which useelectricity      Construct and make drawings of simple workingcircuits      Explain why some circuits work and others donot LessonObjectives:1.    To make a circuit using a battery wires andbulbs2.   To record observations in drawings3.   To predict and then test if a circuit willwork Resources/Equipment:Whiteboard activities (W1,W2)The Lighthouse KeepersLunch - (black sheet of paper on page where Mrs Grinling appears torepresent when light house fails)Electrical components tomake a complete circuitDifferentiatedworksheets:      Can You Help Mr Grinling? (1i - iii)      Mr Grinlinghas a go? (2i ii)      Will it work ? (3i - iii) Introduction Classification exercisesusing the whiteboardWhat have all thesepictures got in common? (light producers)Which of these needelectricity? (whiteboard activity.Which of these are batteryoperated/main operated? (whiteboard activity 2)Discuss the dangers ofmains electricity with the childrenSorting activity Main Read first part of TheLighthouse Keepers Lunch. Dilemma the lighthouse light fails - Whatcould happen? (ideas re shipwreck etc) What caused lighthouse lightto go out? (Childrens possible answers - power out, bulb broke,big wave came) How could e solve this problem - (use batterypowered circuit as a back up)Task - You have to show Mr Grinling how to dothis. Activity 1:      Children to make a model of how to light up bulb Differentiation Mixed pairs/children who are more able couldget own equipment      Children to draw circuit when have successfullylit the bulb. (1i 1iii). Activity 2:      Teacher modelled explanation of will it worksheet using single example (2i-2ii)      Give the children Mr Grinlinghas a go!. They have to decide whether or not they think(predict he was successful or not) differentiated sheets. Testcircuits to see if they were correct. Plenary: Feedback from children on circuit diagrams will it/wont it work? (2i/2ii). Sort large images      Children are encouraged to use specific languageto say why it will/wont work e.g. it is a complete circuit, thewire isnt touching the bulbholder.      Children have to predict whether the bulb willlight up in diagrams (3i-3ii) (and more able give reasons foranswers)

Levels:

 Level1 Construct acircuit with help.     Identify commonappliances which use electricity. Level2 Identify commonappliances which use electricity.     Construct andmake drawings of simple working circuits     Explain whysome circuits do/do not work. Level3 Construct andmake circuits which have more than one component     Suggest how wecould make a homemade switch to make light house flash
