Work with a partner to start to create your papier-mâché trenches. You will need to make sure that your trench diarama includes all the components of the trenches (refer to the diagram in your notes), razor wire, sandbags, no-man's land, etc, etc). The picture on the Smartboard should help you as well.
This can be a fun, but incredibly messy project. Make sure you clean up as you go..as NOBODY will be allowed to leave the class until ALL MESS is dealt with and everything is returned to where it belongs.
