Earth+quake+building

For last week 6w has been assigned a technology project. We were given the task of building a building that could survive a earthquake up to 8.0 on the raptor scale. When we went to build the building every one run to the cardboard. Once we all got our cardboard we got down to work. When we were all done we had to test our buildings we had two tests our first test we would take on our own and the second we would take as a whole class. On my first I lasted 3 quakes but on the fourth and final one my building fell of the table. On the second test with the whole class on the first go mine fell over and crushed a class mates building, on the second go when we made the tables jump above the air my building fell down through the cracks between the tables.
