Check out this Truss Bridge from lesson 3A.
This is made out of regular shapes. When we join these shapes together we can make complex shapes from them.
Begin by following this simple 20 second video.
Can you join the side frames and make a roof support?
There are two types 'Criss-Cross' and 'V' shaped. Can you build it?
Extension. Can I build a Cable Stayed Bridge?
In the style of the way we have built the bridges over the last couple of weeks, try to build this cable stayed bridge below. It is the Mohammed VI Bridge and is the longest cable stayed bridge in Africa. It has two very interesting pillars that we can engineer ourselves.
The shapes of the pillars are not oval. They are two custom shapes similar to ovals. You must cut these to make as close to exact as possible.
How will you make the cables? How will you copy and paste? What do you need to rotate? What do you need to make once and repeat many times?
How should I coach my classmates?
Try not to 'Tell' your friends how to do something. Try not to 'Do' things for your friends. Instead, describe what your friends should be doing on the screen. Or, sit with them, side-by-side and show with your screen how something is achieved.
Learning Intentions:
Can I build a Truss Bridge?
Can I coach my classmates to greatness?
Bridge Building Success Criteria:
I can join regular shapes to engineer complex structures.
I can place, cut, join, group and duplicate shapes with accuracy.
Coaching Success Criteria:
I can talk my classmates through the steps needed to complete parts of a bridge.
I can demonstrate on my machine what my classmates should do.
I can talk my classmates through actions such as copy and paste, duplicate, rotate, adjust and move.
I can show my classmates the power of undo.
