I wish I had you as my teacher.

Taping it down actually strengthens the structure because it has flexibility and it just moved the covers so that the actual strain on the flexibility of the bridge was less...

the weight is shared equal

u made it so all the weight in the bridge is shared equally but in a real bridge it would not be equal and it is very short

i realize that these are young children you are teaching but.. it held so many dictionaries because of the weight displacement being spread almost to the edges of the bridge, it also looks like the edges of the dictionaries were at the strongest points of the bridge. put the weights in the middle on a smaller point and it will collapse
the kids did a good job though, that is for sure, cool that you bring engineering into your curriculum, as a future engineer i loved the video

We had an engineering day where students rotated through different activities (build a K'Nex robot, build a paper tower, build a popsicle bridge). They really only had about 12 minutes to build it (we let the glue dry overnight).
I posted this video not because it is an excellent example of engineering, but that it held so much more than any other bridge made in my class. My goal was to get them excited--I think it worked.
