Strong and Stable Structures

The Grade 3’s visited the Ontario Science Center this week to assess the effects of strong and stable structures on society and the environment.  We reviewed the fact that a structure is a supporting framework, with a definite size, shape, as well as purpose, and that a structure holds a load.  We were able to identify structures in the natural environment and in the built environment.  Can you sort the following into natural structures and human made structures:  nest, towers, flag pole, tree, bridge, beehive.  All structures must have the ability to maintain balance and stay fixed in one spot.  Our Grade 3 engineers used all of this knowledge to build bridges and towers.  Take a look at our Strong and Stable structures.
