My Opinion

I think that Emily and Ally's structure was the most stable out of everyone else's because it

#1 The building was more stable when the mass was put on the bottom floor rather then the top because the centre of gravity was down lower and that makes things more sturdy.


#2 The centre of gravity moved to the edge of the building when the mass was moved to the top floors because the building was off balance.


#3 When we moved the mass to the edge of the building on the bottom floor it really unstable because it didn't have a wide enough base to level out the mass and keep it sturdy, but when we put it on the top floors it got more stable because the building was quite balanced through out.


#4 The changes that we could make to are building would be to put more straws on the bottom because a wider base would male it so it wouldn't tip as easily.

In your opinion out of all the structures built which building was the most stable at each floor for both tests? Why do you think this is?

Responses for science

1) My building was less stable when

Moving the Mass

After measuring with the 100-g mass of the building respond to the following questions as comments underneath the picture of your structure.

1) Is your building more or less stable when the mass is placed on higher floors?

2) Describe how the centre of gravity moves as the 100-g mass moves up each floor.

3) After you moved the 100-g mass closer to the edge of each floor rather than in the middle what differences did you notice in the stability of the building.

4) What changes could you make to your design that would make the building more stable when the centre of mass is high or near the edge of a floor?
