Switzerland poster


Room 5 did posters on countries during reading time. I choose Switzerland. This is only the first page of my project.  One fact that I found out about Switzerland was that the population was 8.372 million people.

How a fire alarm works?

Have you ever wanted to know how a fire alarm works? Well today I’m going to tell you.

Smoke is made up of tiny particles (bits) and that's why it can leave a smell or make you cough.

Some smoke alarms have tiny lights inside and if the smoke particles get in the way of the light  this sets off the smoke alarm.

A different type of alarm uses chemicals which give an electric charge. Smoke particles inside the detector change the amount and type of electric charge and this sets off the smoke alarm.

When the smoke alarm goes off accidentily you can either wave wind towards it or take its batteries out.

Also make sure your smoke alarms are working properly, this can happen when the clocks go back or forwards.

I hope you learnt something by reading my explanation.
