Hi there! Wow! I can not believe that class Fe7B has done so much work already!! In science we have already been given our summative projects! We were given the choice of constructing a tower crane, trebuchet or bridge for our projects. Since we've learned so much already about forces, stresses and most importantly failure, our class is ready to build our structures! Here is an example of work from our previous oil derrick project that might help people understand more about structures and how they work.

•From the top view of this model structure, you can see that the platforms are all aligned causing any weight being exerted on the structure to be more balanced out making the structure more stable.

•To add more stability to the structure, straws were wrapped around the three main pillars to keep them from buckling out when under compressive forces. There were “x’s” placed through the three main pillars to keep them from buckling inwards as well when also under compressive forces. These supports steadied the pillars and kept them from moving when under loads. When unable to move, the pillars can not create stress on the platforms leading to no shearing.

As for math, we have started a new unit on Geometry and Measurement. Our last lesson was on building 3D shapes from their nets. Here's an interesting fact. Did you know that there are 11 nets that can be used for a cube? Next week I will show all 11 nets. For now, try and figure out this problem!

I'll post sooner than later!
