Defense Structures and bombs

This week Tuesday we had someone important come into our class to talk about Bombs,Defenses, and much more. His name was Issac Chang, Or if you prefer to call him Mr Chang. Issac told us about what was used to keep things safe and what kind of bombs that are used in the air force. Mr Chang (Issac) Is apart of the NZ air force. Mr Chang showed us photos of different kinds of bombs,Layers and much more of what he uses in the air force to protect his area. He told us information and facts about each of the photos. Also he talked about layers. The first layer was camouflage, camouflage is to cover the things that are important, so basically the camouflage blends in with the environment.

Mr Chang gave us a challenge, it was to build a structure to keep a helicopter safe. The materials we used was one piece of pare and 8 straws. We were allowed to do anything with the materials, We were not allowed to get another paper. Once everyone was done with making the structure, we could now test it out to see if the helicopter would survive the Shock waves.

Our group made a cylinder shape with the paper and stuck straws in the middle of the cylinder. The teachers had to stick the paper down with tape. The tape was to give more support for the structure. If the structure stayed standing and the helicopter didn't get broken then the structure was a very sturdy structure. Everyone made a very cool structure, some were not so good because it would fall and lean to the side. SO it just didn't stay standing.
