Communication Technology In WW1

This is what I did In my Maths Class. We had to make a presentation and we had to write what we did and search on Google. We had to figure it out but we used some of our own words. This Term we are learning about Tinkering Tools and Toys. We had to do a Presentation and finish it in only 15 mins but I finished it and I wanted to put this on my blog as quick as I can but I took my time and I just finished it normally. I really Hope you guys think that It Is good.
