Defensive structure

This week on Tuesday we had a special guest come in. his name was called Mr Chang. Mr Chang Is a person that works for Defense force. He came to our class to talk about Bombs, Explosives and guns. We could have also called him Issac because he felt old when He got called Mr Chang. 
First what we talked about was defensive mechanism. We talked about it being camouflaged. Camouflage means something that blends in. 

Next what we talked about was bombs. The first bomb we saw was a dumb-bomb. A dumb-bomb is a bomb that has no control and just drops so that is why they call it dumb-bomb. After talking about that we talked about Smart-bombs. Yes the smart-bomb is controlled. The difference is of the shape. The smart-bomb is longer. We also watched a video talking about bombs and explosives. We also had to see the shape of it.

After that we got to be in groups of five. The activity we had to do is make something safe for the toy helicopter so it doesn't get blown away.  The equipment that we used was straws, paper, tape and scissors. at first we didn't know how to do this and then we thought ov'e an Idea. Lucky our one survived. We were so happy that it survived.

I have enjoyed doing this because I got to learn more and got to do an activity using straws and paper.
