Get Ratty!

In this activity children are challenged to design electrical circuits that would alert the user in different ways when an object or animal is sensed.

Description

Rentokil has developed traps that send you an email when they make a catch. It takes pressure measurements to distinguish between vermin and family pets, and it kills quickly and humanely by releasing carbon dioxide gas.  

Children are challenged to design electrical circuits that would alert the user in different ways when an object or animal is sensed. 

Learning Objective:

-    to construct circuits, incorporating a battery or power supply and a range of switches, to make electrical devices work

Children will learn:

-    how changing the number or type of components in a series circuit can make bulbs brighter or dimmer

-    how to represent series circuits by drawings and conventional symbols

-    how to construct series circuits on the basis of drawings and diagrams using conventional symbols
