6th class made periscopes

We made periscopes with our teacher. It was tricky but we got there in the end!


We held the periscope sideways and had fun looking around corners, we also had fun looking at each other from inside/outside the classroom and from under and over the tables. It was good fun after all the hard work. It was hard work making sure all our measurements were right. 
We found that because of the two parallel mirrors that are facing each other that are used in making the periscope the light bounces between the mirrors
We found that periscopes were used in World War 1 by the soldiers in the trenches so they could see their enemies without being seen themselves. Some people use periscopes at matches, concerts and parades so that they can get a better view of what is happening, periscopes are also used in submarines and can be up to 12 metres long.( H. 6th class )
