Lesson Four – Using Switches
This science teaching pack for Key Stage Two gets the children to explain and record how to build a circuit switch to use in an electrical device to solve a problem by constructing an alarm that will occur when a specific event occurs.
The class can record how to build a model to show how to make an electrical alarm to warn about an action such as a dog trying to steal a biscuit from a kitchen.
Download this teaching pack including a lesson plan, classroom activities and an interactive presentation to explain and record how to build a circuit switch to use in an electrical device to solve a problem by constructing an alarm that will occur when a specific event occurs
Activities in this teaching pack include display posters to identify and describe ways of fixing different circuits so that they can power electrical devices and worksheets to select and build a circuit switch to use in an electrical device to solve a problem by activating an alarm.
The interactive presentation gets the children to explore how to build a circuit switch to use in an electrical device to solve a problem.
This lesson is part of a science scheme of work to get the children to identify and record how to build a range of electrical series circuits to control and manage devices and components for different functions and outputs. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
-
Ordering and Changing
Explore and record how to order three digit numbers by the place value of their digits and how the digits in a number change their numerical values when finding ten and one hundred more or less
-
Changing Hundreds
Explore and record the matching number sums that are one hundred more and less than different three digit numbers to show changes to the place values of their numerical digits
-
Digit Changes
Identify and record the matching number sums that are ten less than different three digit numbers by illustrating changes to the values of their hundreds, tens and ones digits
-
Changing Numbers
Identify and record number sums that are ten more than different three digit numbers using abacus diagrams to model their changing values
