Our Strong Structure
by Laura and Robyn
How we (Robyn is my partner) made our strong structure
is we made lots of pillars and after that we taped them
together and formed them into a box shape. We made three
boxes and taped them on top of each other and put an x
in the middle of the second floor. After we put
that together Robyn made a roof. It was pointy and long
and we also put
double layers on some of the index cards. After Mrs.
Hester helped us
weigh our structure and it weighed 60grams.
Then we started to hang washers in the middle card
that was going across the structure. First we put 10
washers on the structure and then Robyn kept adding
washers and then it started to wobble. We tried putting
the washers on the opposite side of where the wobbling
was but it didn't work so we just stopped. In total the
washers weighed 460 grams in all. I learned that it
doesn't matter how high it is because the smaller
structures held the most.
