Inquiry

 This week, our company (Life Savers) brainstormed ideas for an emergency shelter design. We needed to think of the structural shape and design of the emergency shelter. We also needed to think about what our shelter will be designed to resist.

First, we sketched on a piece of paper of what shape we're doing for our emergency shelter, and my group picked a triangle. This is because a triangle have sharp points and it can make things slide down from it

Next we used a software called sketchup to make a 3d design of our shelter. Sketchup is a program that allows people to design and create anything they want in three dimensions.

We decided to make the shelter out of tungsten because it is strong and brick because it is thick. We think these are suitable materials for water and wind natural disasters.

Some changes that we want to make are making the shelter big because it looks small and want to make the inside spacious so that we can put that things we need to survive 

The size of the entrance is 2.15 meters and the size of the shelter is 3.45 meters just in case of an emergency. The walls of our shelter are pretty thick because the shelter is made out of tungsten brick. There should be windows so that the people inside the emergency shelter are aware of what is happening and can identify if it is safe to exit the emergency shelter. The windows should be fairly big, about 2 meters so that people can see out of them clearly.
