A description of the step
Define the problem
I need to build a structured bridge
in order to hold as many pennies as
Brainstorm & Design
More than 10 inches flat surface in top.
Triangles on the bottom to hold up the bridge.
20 straws in total to use.
Get the top surface done. And make sure it can stand with
those supports. Then put a couple of triangular shaped straws
on the bottom. Make a long strong top, so the pennies will have
room to lay on the bottom.
Test/ Evaluate
I will put one penny at a time on the top and see how many it will hold
it. See how long the bridge will hold a certain amount of pennies.
