Science Club weeks 2 & 3 are follow up to our
week 1 disaster. We are learning about the work of Buckminster Fuller and his Geodesic Domes.
The combination of curve and triangle in dome structures makes them strong and stable during an earthquake. Dome houses are also economical and environmentally friendly, requiring only a small amount of materials.
According to Buckminster Fuller: Poet of Geometry
by Cole Gerst, Fuller's personal Dome Home in Carbondale IL "took only seven hours to build."
The American Institute of Architects calls the geodesic dome “the strongest, lightest and most efficient means of enclosing space known to man.” (pacificdomes.com)
Preparation:
straws - Perfect Stix 20" Extra Long Neon Straws - Pack of 300
35 straws, 20 inches long
30 straws, cut to 17.5 inches
our dome design is smaller and simpler than the illustration above, which shows 3 colors for 3 strut lengths
paper clips - enough to make the three following types of connectors
a huge thank you to the creator of DesertDomes.com!
the connectors slide inside the straws to hold them together, as shown below

Activities:
review last week's disaster
explain Richter Scale and demonstrate with a math material to scale
level 1 - 1
level 2 - 10
level 3 - 100
level 4 - 1000
level 5 - 10,000
imagine level 6 - ten 10,000s
imagine level 7 - a hundred 10,000s
imagine level 8 - a thousand 10,000s
imagine level 9 - ten thousand 10,000s!!!
a level 6 would be ten of these 10,000 squares!
recall the destruction in the 1811 New Madrid Earthquake (8.1)

use straws and paper clip connectors to build a geodesic dome
DOME NOTES
As part of a Housebuilding summer camp in August 2018, my three daughters successfully built a geodesic dome with these straws:

I could never have done it without Natalie and Leah!
This year we were determined to do it again. And so I am going to take VERY detailed notes as to how to be successful!
We had a lot of questions. Do you make the stars first (some with 5 spokes and some with 6)? Do you start at the top and work your way down? Do you start at the bottom and work your way up? Do you make all the connectors first or construct them as you need them?
As soon as my students and I figure this out, I will write it up!

Many thanks to desertdomes.com for help with the math. This is an amazing website which helps you build your own geodesic dome. Simply put in the radius of the dome you wish to build, and it will tell you how long to make your struts and how many of each length you will need, plus how many connectors of each type you will need.
