The "Strong and Stable Structures" activity packet is aligned with the Ontario Grade 3 Science curriculum expectations. This activity packet includes lessons, worksheets and experiment instructions that can be used to supplement your "Strong and Stable Structures" unit.
Some of the readings presented in this packet might need teacher assistance to understand some of the concepts. However, the readings are presented with some pictures to help scaffold learning.
The expectations that addressed within this packet include:
* Define a structure as a supporting framework with a definite size, shape, and purpose, that holds a load;
* Identify structures in the natural environment and in the built environment;
* Identify the strength of a structure as its ability to support a load;
* Identify the stability of a structure as its ability to maintain balance and stay fixed in one spot;
* Identify properties of materials that need to be considered when building structures;
* Describe ways in which the strength of different materials can be altered;
* Describe ways to improve a structure’s strength and stability;
* Explain how strength and stability enable a structure to perform a specific function;
* Describe ways in which different forces can affect the shape, balance, or position of structures;
* Identify the role of struts and ties in structures under load;
* Investigate how various materials and construction techniques can be used to add strength to structures;
* Investigate the effects of pushing, pulling, and other forces on the shape and stability of simple structures;
* Use technological problem-solving skills and knowledge from previous investigations to design and build a strong and stable structure that serves a purpose;
* Assess effects of strong and stable structures on society and the environment;
* Assess the environmental impact of structures built by various animals and those built by humans;
