- a hot and dry climate;
- a cold and snowy climate;
- a tropical climate;
The testing criteria was:
Cold and snowy climate - the house must be able to keep the roof from caving in when we put a lot of snow (weight) on top.
Tropical climate - your house must keep dry a piece of tissue paper inside when we pour water (rain) on top.
Points were allocated for:
25 points - House stands by itself
50 points - House either supports load of snow (eg. dry sand), keeps tissue dry or stops ice cube melting
10 points - A clear, detailed construction sketch was completed. All resources should be easily distinguished. All important design features and all critical measurements should be labeled on the sketch.
20 points - A structural analysis of your house was completed. The following questions should be answered clearly and completely:
· During construction, how did you test the strength and stability of your structure?
· During construction, what strategies did you use to strengthen the weaker areas? Why?
· What are the strongest parts of your house? Why?
· What are the weakest parts of your house? Why?
Each group was awarded maximum points for a free standing structure and ALL structures survived the tests. The winning structures were those that had very detailed planning (maximum 10 points) and completed a structural analysis (maximum 20 points).
