Grade 7 is getting ready for student led conferences. Here is a cantilever bridge that allows us to feel the tension and compression. It works!

Students are translating their plans into bridge prototype designs and trying to stay on budget. This week a dynamic load will be added to their bridges until failure.
In mathematics, grade 7's have been busy, using percentage to verify how close their central tendency calculations could get to the real wall lengths. Central tendency calculations were compared to actual blueprint measurements for our classroom and a few others in the school. One student stated, he was shocked to see how his median calculation could be 98% accurate when his range of data was 8 meters. Many students witness first hand how the median could be "outlier resistant" and was the best choice to represent their classroom measurement data. This work started out with one simple outcome, to determine the area and perimeter of a room, and quickly became an authentic space to use data analysis. Student reflections of the classroom measurement inquiry can be found on FreshGrade.
In Science, students explored bridges on the Bow River noting joining technology, material usage, and the types of bridges they explored. Students took inspiration from these structures for their bridge design challenge. |
