Problem Statement

To come up with the next steps of building a full scale igloo.

Team Members

Summary

We began by reading over the work done by the first group on this project. They made some considerable progress on the math associated, so we started reading that to learn it ourselves. Once we had figured it all out, we cleared up the math involved in calculating the size of blocks in an igloo. Along with this, we drew up a table with all the projected sizes of the blocks necessary in construction We also researched some alternative methods of constructing an igloo.

First Week

Our goals is to start the process of building a full scale igloo. We picked up the math tutorial from previous team and calculated the number of blocks needed for every every layer of IglooTutorial. We discussed the material to use for the igloo but its undecided. We decided to build the igloo in middle of campus, front of the food court.

Second Week Task

Calculate the dimensions of every block base on the math tutorial.

Second Week

Layer (Height)	Radius (ft)	Circumference (r x 2pi)	# of Blocks	Layer Angles (Degrees)
1	3.44	21.61	14.4	16.21
2	3.18	19.98	13.34	32.17
3	2.90	18.22	12.17	45.97
4	2.60	16.33	10.89	56.98
5	2.25	14.14	9.43	65.77
6	1.84	11.56	7.7	72.95
7	1.40	8.80	5.44	78.69
8	0	0	1 pentagon piece	Undefined

Thrid Week

Interior angle = ((number of blocks - 2) x 180 )/number of blocks

Layer (Height)	Number of sides/blocks	Interior angle (Degrees)	Angle should be cut (degrees)
1	14	154.3	25.7
2	13	152.3	27.7
3	12	150	30
4	11	147.3	32.7
5	9	140	40
6	8	135	45
7	5	108	72
8	5	108

Material List

1. Igloo construction book

2. Calculator

Time

We worked a combined 20 hours on this project

Next Steps

The next group will probably want to pray for snow. At this point, everything is in place. All we need is some snow to actually build with. Maybe purchase a snow saw just in case.
