Resource 6: Periscopes – ideas to get you started
Teacher resource for planning or adapting to use with pupils
Start by finding two mirrors.
Hold one in each hand and see if you can use them to peer over a wall or see round a corner.
When you have a good image over the wall or round the corner, stop. Look at how the mirrors are arranged – what do you notice about the angles?
Now you can use your observations to build a periscope. The images below give you some ideas of how to do this.
How will you evaluate your periscope? Are any of these criteria useful? Can you think of any more?
Draw up a table of the criteria you choose and use it to record judgements on everyone’s periscope.
