Earthquakes:
When the earth’s surface shakes, it has a sudden trembling of the earth’s surface. It is regarded as on of the deadliest natural disaster. Earthquakes are a huge problem in countries and have many impacts on a city. It can leave a lot of people homeless and hurt. Therefore the importance of earthquakes and the building structures became a big focus for people to be safe.
Year 9 science engineering challenge:
In our year 9 science class we had a challenge to build a earthquake resistance model of building, We documented the whole process off building and making it.
The challenge:
We had to create a model out of pasta and blue-tack, we had a budget of $60. We had to resisting the shaking of a table that shakes without falling for about 10 seconds. The spaghetti was $1 per 10cm and the blue tack was $1 per gram. It should of at least been 30cm with a base on the bottom and on the top for a piece of paper on the top and a leg person to stay in a case of an earthquake.
It is very important in the world we live in today with climate change it helps us learn about different buildings and there outcomes in that situation of an earthquake striking and there ways they cope also the ways they solve there situation in it happens. This also helped us work as a team and come up with many designs and thought process into making the building for a safer options.
Our design and process:
We had many discussions and a lot of thinking in which ways might help us make a good building that is strong and would not fall in the matter of an earthquake.
Some of our main problems that went into making the pasta building with blue-tack was the pasta breaking when we put it into the blue-tack. Also it was very hard making the structure sturdy for us to build up and having a base on top when the earthquake happens. It was very had with the budget that we had and the pricing when we had to buy all our materials. We found a solution by braking down the process and minimizing the size of the base at the bottom. We didn’t use as much pasta and blue-tack as we needed so if there where any problems in our design we could fix it and to know where all our weakest points were at the time.
When we created it:
We built our model very slow and not rushed as we didn’t want it to break our fail when we had the test. We measured the height of it and made sure we where in the right height and length regnum. We had more experince on our final making of the building as we did make one before that, so we knew what to look out for and what needed to be fixed and changed.
Testing:
We did not take a video of the test as i forgot but the test for the last one went very good. There where no problems or issues when we where testing it. We put it on the table and started shaking it for 10 seconds at a time. We needed to see if it would hold up in a real life earthquake, so we put a little Lego person on top of the building with a peace if paper luckily the person did not fall off and all was good for those 10 seconds. This is because we had a good base on the bottom for the whole building to be up tall and not start falling apart when we where shaking it. Our building was within the price range and the perfect among of height and weight.
