Earthquakes PBL Project

The project was about learning how to apply earthquake-resistant technologies to a building to make it safe. The driving question was: How can we, as structural engineers, construct a two story house in CA for Tony Stark that will withstand seismic activity?

Our design for Tony Stark (see below) was a rectangular prism made out of popsicle sticks. We used straws for the four corners of the buildings and attached everything using clay and string. For extra durability, we added toothpicks in the corners.

By completing this project, I learned many of the technologies that are applied to modern-day buildings to keep them safe from earthquakes. For example, I learned about using panels to strengthen walls. So in a case of an earthquake, the walls won't come down as quickly and will be able to withstand more.

Invention Convention

The environmental problem that my innovation is solving is water pollution. Water pollution is actually quite a huge problem. Many people dump trash and other junk into water, not even giving a thought about where it goes. This trash and junk end up clogging the water, creating a new home for bacteria, virus, and other pathogens. People could end up drinking this water and die from the disease caused.

However, my innovation, the Solar Water Purifier, helps to solve this. Using a heat exchanger that's powered by a solar panel, it's easy to purify water. Contanimated water flows through the heat exchanger. The heat exhcanger heats the water up so much that the water boils. It's widely known that boiling is the safest method of purification because it gets rid of any pathogens living in the water. After coming out of the heat exchanger, you have clean water. The only downside to this invention is that it can only get rid of pathogens, not chemicals.
