8th grade students tested their bridges Friday, May 29 during the Bridge
Exposition, part of the Bridges to STEM Careers project. Thirty bridges
were tested by adding weight to each of the spans until collapse. Students and parents are welcome to check out the final ranking on the
winning bridges webpage!
A special thanks to our guest experts, bridge
engineers and architects from the Pittsburgh region. Representatives from HDR,
Inc., Michael Baker Corp., and Penn Dot District 11 used their insight and expertise to help enrich
this learning activity. Bridge designs can be seen on the classroom website through the
gallery page.

| A leader board was on display in the library during the event so students could see how their bridge compared to others in the class. |
 |
| Storing thirty bridges in Lab 110 is no easy feat! Here are all of the models prior to the Exposition! |
