This week we started working like engineers. We were exploring how shapes and materials made structures stronger. We did an experiment where we tested the strength of materials that we will use to build our bridges. We discovered that even though string and pipe cleaners were flexible they were also really strong. Later in the week we did an experiment that taught us that corrugated materials and arches were much stronger than flat bridges. Finally on Thursday we did an experiment that involved different columns. We found out that cylindrical columns were stronger than triangular or rectangular prisms because the weight is spread out evenly.
We started reading a new novel in the mornings. We are now reading I Survived the 1906 San Francisco Earthquake. The story is about a boy who was growing up during the California Gold Rush. Lots of the kids in the class signed out other I Survived books from the library this week.
On Monday we have an expert coming into talk to us about the engineering process and how they approached building a bridge while at the U of C.
Here is some extra homework for people to try this weekend.
