Meaning of Home appliance

Home appliance is defined of as “an instrument or device designed for a particular use or function”. Collins English Dictionary defines “home appliance” as devices or machines, usually electrical, that are in your home and which you use to do jobs such as cleaning or cooking”. The broad usage, afforded to the definition allows for nearly any device intended for domestic use to be a home appliance, including consumer electronics as well as stoves, refrigerators, toasters and air conditioners.

 

Activities

You can form groups of 3 members of mixed abilities of your learners so they can identify some common household electronic appliances using chart (example above) of electronic appliances and real objects of household and name appliances brought to class.

You can allow learners to sketch household electronic appliances and label them.

Guide learners to state a particular use or function of all the selected household electronic devices. Examples are: electric iron, blenders, water heaters, electric fan, vacuum cleaner, electric stove, refrigerator, television, microwave, toaster, air conditioner and washing machine (Take the simple ones to the classroom while bigger ones will be displayed on a chart/computer).
