Bridge essay

A detailed Summary of Bridge essay


In project one, we tested the thickness of the bridges. We measured construction paper and cut the paper six inches long and four inches wide. We set the bridges between tables and recorded our results. We had one bridge and had it hold fourteen pennies. Two bridges held twenty-two pennies. Three bridges held thirty-three pennies. Four bridges held sixty-seven pennies. When I graphed this data, it was linear.

In project two, we tested the length of bridges. We measured and cut construction paper four inches wide and four inches long; five inches long; six inches long; seven inches long; eight inches long; nine inches long; and ten inches long. Again, we set the bridges apart on two desks, letting them overlap the table an inch on each side. Then we started to add pennies to the bridges. The four inch long held sixty-seven pennies; the five inch long held thirty pennies; the six inch long held twenty-five pennies; the seven inch long held fifteen pennies; the eight inch long


· Errors I could have made are: bad measurement; cup position; drop of pennies; desk position; imprecise; paper defective; or miscounted.

held thirteen pennies; the nine inch long held ten pennies; and the ten inch long held seven pennies. When I graphed this data, it came out as a non-linear graph.
