Hayley Nash 3/27/07 Earthquake Lab

Question/Purpose: What design features resist earthquakes best? Does experience with design allow you to make a more earthquake resistant structure?

Hypothesis/Prediction: I believe that a building would need to be as short as possible to resist falling over. Experience with design would help you make because you would know what helps structures in earthquakes.

Identification of Variables: The manipulated variable is the design of the building. The responding variable is how the build resists the earthquake. The controlled variable is the length of the earthquake.

Materials: 20 toothpicks 10 marshmallows Something to simulate an earthquake (jello)

Procedure: 1.	Design and sketch 3 different building designs. Each design must have a base that is 2 toothpicks long and 1 toothpick wide. 2.	Build one of the designs with the toothpicks and marshmallows. 3.	Test the design with a simulated earthquake. Record how your design and the other groups’ designs stood up in the earthquake. 4.	 Design a new and improved building design based on what you’ve learned when testing your design.

Data Table:

Conclusion: The smallest buildings were the most stable in the experiment and the building with the strong bases. A larger model would be difficult to build out of toothpicks and marshmallows because it would not have enough weight to hold itself steady. I know now that weak bases fall apart during an earthquake and that will ruin the entire building.
