Assignment 2 : Geodesic Dome

Day     : Wednesday

Date    : 28th July 2010

Venue : DK E48B, HBP

Time    : 09:00-11:00 am

Today, Mr. Wan give us a new assignment. Mr. Wan asked we need to build a geodesic dome. In build a geodesic dome, there were 6 element that plays its own part. The element are:-

Intention:

To build of a model of a geodesic dome.

Act :

We start to build of a model of a geodesic dome using bamboo satay sticks.

We build the model in 2v.

Actor :

Normah (Me)

Rule :

Cut the bamboo satay sticks at the same lengths.

Make the dome at the right time to finish the dome.

Place :

In my room.

Product :

A model of a geodesic dome.

Material :

Bamboo satay sticks.

Masking tape

Scissor

Cutter

Ruler

A marker

Step how to make a geodesic dome :-

• First of all, we need to decide what type of dome we want to build.

• Once we have decided what kind of dome we are going to build, we need to decide on a size. So, we choose to build 2v dome.  

• Then, we use dome calculator to calculate the radius for dome. There are only two lengths involved for 2v dome build.  The number of 2v dome radius is 12cm. The side A which is 7cm and side B is 6cm.

•  We need to measure the length of bamboo satay sticks and then point it.

Point the length of bamboo satay sticks.

•  After that, cut the bamboo satay sticks into 6cm and 7 cm.

Cut the harder sticks.

Cut the bamboo satay sticks into 6cm and 7cm

   

6cm long

7cm long

• Next, joining 10 sticks (6 cm long) using a masking tape.

put the sticks end to end.

Then, bend the 6cm sticks with masking tape.

• Then, bend the sticks until it shapes a decagon, after all the 10 sticks are joined.

Make a decagon

its base dome

• After that, joint 2 sticks together  (6 cm with 6 cm long and 7 cm with 7 cm long). Each 6cm and 7cm can make 5 joints.

 Joints 2 stick together.

• All of sticks are joint alternately 6cm and 7 cm.
  

Stick joint alternately

Make another decagon with joint the 6cm until 10 sticks. The decagon is then stick on to the edges of the triangles.

A decagon

• Then, make a triple sticks joint. Stick it on the middle edges of the triangles with the 6 cm long stick and the left and the right side of triangle with 7cm. At the middle of pentagon should make a star shape.

Before complete a dome

• Finally, after a star shape are put and bend to the top a dome so, my Geodesic Dome are completed.
