Mr. Petersen and the Year 8s have studied and built bridges in Technology class.
This is what they said:
"The bridge project is meant to teach the students how forces work, during our project we mainly focus on tension and compression. After a series of lectures they will use their knowledge and apply it towards building a bridge made out of popsicles, string and woodglue. This they will produce within three lessons.
"After completion we will test them by putting stress on the bridges through the use of dumbells, when they will no longer suffice we use people as weights."
