Geo-domes in 2nd class

We constructed a Geodesic Dome in class. First, we made 3D structures using toothpicks and Plasticine to see which structure would be the strongest to use. We found that triangular structures worked best. We made lots of triangles using rolled newspaper and taped them together. We had to make sure that each one was the same length. We attached an oxygen supply to our Dome. We found out lots of fun facts about life on the moon!

Eco Friendly Newspaper Bags

Take a look at our Eco friendly bags. We researched gift bags and discovered that the majority of them are made in China. We wanted to reduce the air/land and sea miles used and thereby reduce our carbon footprint by making bags of our own using old newspapers.

Design a Bridge Challenge

Task: Design a bridge

Method:

Using blocks, paper, books and crayons to test we designed bridges to see which ones were stronger and could hold the most amount of crayons. We manipulated our structures to increase their strength by folding the paper used, using double layers of paper, creating arches and structures for extra support.

Conclusion:

The material from which a structure is made is important but you can strengthen a material by changing is shape. Bridge designers often use different shapes for example: arches and triangles. The curve of the arch spreads the load on the bridge and makes it stronger.
