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 andbulbs

2.   To record observations in drawings

3.   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 circuit

Differentiatedworksheets:

      Can You Help Mr Grinling? (1i - iii)

      Mr Grinlinghas a go? (2i ii)

      Will it work ? (3i - iii)

Introduction

Classification exercisesusing the whiteboard

What 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 children

Sorting 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)

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
