Problem/PurposeWhat types of structures can be built to best withstand earthquakes.

Research In research, the information showed different materials that can be used on houses to make them stronger. We learned about using beams and poles to hold up houses. We also learned about designing houses to withstand earthquakes. In one article it told us about building heat systems that shut off when a earthquake starts. Last of all we learned which types of houses best withstand an earthquake.

Hypothesis If we build 3 different structures, the clay structure will best withstand the shaking. This is because clay sticks together and it holds up well.

Materials

Procedures1. Build three medium size houses made out of clay and use

toothpicks to keep the clay together.2. Build three medium houses made out of popsicle sticks.3. Build three medium houses made out of cardboard.4. Put 1 clay house on shake table, have someone count the

number of shakes it takes to fall.5. Do this for the rest of clay houses.6. Record and write down things we notice.7. Repeat for cardboard and popsicle sticks.8. Find similarities and differences between structures.9. Conclude.

Conclusion Part 1Our hypothesis states that if we build 3 types of structures than the clay house will best withstand the shake. Our hypothesis was incorrect. The clay house fell in the fastest time. If we could change our experiment than we would’ve tried to make all the structures as alike as possible. This could of made our information more accurate. We also could of used a stronger type of clay. A factor that effected our results was that all the structures were not the same size. This could have an effect on our results.

Conclusion part llOur results relate to the real world because we noticed that the clay houses are weak. Villages might not want to build clay houses because if there was an earthquake, they could fall. A wood house would be the best type of house because it is the strongest and would best withstand an earthquake.
