Week 1 entry: The lecture for this week focus on introducing the content of the subject constructing environments for the semester 1, in 2014. It laid out what are the goals we are aiming to achieve through this subject and introduce the students to the text book. In the first tutorial, we were given the subject guides and the timelines of the whole semester. Also, we were divided into groups to complete activities.

Tutorial activity Each group was provided one big box of small wood cuboid blocks. We were told the task was to use those block to build a tower as tall as our tutor (around 1.8 meters) in 45 mintutes. The very first problem my group was facing is determing the base of the tower, in which shape we were going to build in order to reach that height and still remain firm. Round shape seemed like the easiest option we had, and we thought it would save the material also (figure 1). The following question would be how we would distribute the blocks, how many layers we need them to have no gaps in between (figure 2)

My group decided to choose cylinder for the body, because we think it would be easy to adjust the radius and more strong foundation. When the foundation seemed to firm CONSTRUCTING ENVIRONMENTS

enough to support the load path, we started to leave the gaps to speed up, however, the gaps between the blocks were hard to decide. Too big may lead to major collapses. Too small would waste more time. When we got to the two third of the tower, we soon run out of the material, because we wasted lot of material at for the one third of the tower.

Week 2 entry: This week lecture we were focusing on frame works. We introduced a fun activity in the lecture, designing a frame work to support a well so that it can eventually can support the load of a brick. Ideas as showing (figure 1 and 2)

tutorial activity : At the end of week 2, we were told to cut four wooden boards into thin sticks. And build a tower that reachs the ceiling. We made up our mind to a triangular shape base, which provides the best support for structure under compression. At the start, we divided a stick into three equal parts for the base. After triangle shape was formed, we moved on to add up the height. The joint was the combination of using surface connector, glue and point connector. In this case, the structural is geometrically equal, so it makes the frame can resist more forces, and more rigid than other groups. CONSTRUCTING ENVIRONMENTS

, pins. Left: we didnâ&#x20AC;&#x2122;t think super glue was strong enough for the joint to holding up the tension, so we also used pins to make the structure more firm .

Right: we joint every triangle for the length of a stick to make it even, and therefore, support the load evenly.

Left: Our tutor was trying to test the ability for the compression. This is a work from other group.

Left: Our group work wasn’t as fragile as other groups’, because of our triangular shape base, and geometry in form, which make it best to support tension.
