Forces & Structures Resources

     This is the LAST resources post regarding my Grade 7 Science curriculum planning and it covers the unit of Forces & Structures. All together, there are four units covered over the course of the school year and I have been sharing my individual unit breakdowns and online resource database. Until I actually meet my students and spend time learning their needs and interests, I have been building a plethora of resources to have in my back pocket as we make our way through the school year. Over the past 2 months, I have been sharing these resources with you! Check out my previous Grade 7 Science resources posts, broken down by individual units:
- Interactions with Ecosystems
- The Earth's Crust
- Particle Theory of Matter

     This unit was really enjoyable to plan out because it lends itself very naturally to having a lot of hands-on building activities. In regards to my full year planning, I have placed this unit as our very last one so that students have an opportunity to have lots of busy, hands-on, exploratory learning opportunities at the end of May and June. I feel like this will be a good fit for that time of year when students are not feeling like being in the classroom listening to lecture or working on written assignments.

Forces on Structures
Enduring Understanding: Structures are under internal and external forces that affect their strength and stability.
7-3-01     Use appropriate vocabulary related to their investigations of forces and
                Include: frame, shell, solid, centre of gravity, stability, compression,
                tension, shear, torsion, internal and external forces, stress, structural
                fatigue, structural failure, load, magnitude, point and plane of application,
7-3-02     Classify natural and human-built structures found locally and around the
                Include: frame, shell, solid
7-3-03     Identify the centre of gravity in a model structure, and demonstrate that
                changes in the location of a structure’s centre of gravity affect its stability.
7-3-04     Identify internal forces acting on a structure, and describe them using
7-3-05     Identify external forces acting on a structure, and describe them using
7-3-06     Recognize the internal and external forces apply stress to structures, and
                describe examples in which this stress has lead to structural fatigue or
                structural failure.
7-3-07     Investigate to determine that the effect of a force on a structure depends on
                its magnitude, direction, and point and plane of application.

Analyzing & Designing Structures
Enduring Understanding: Specific materials & structural shapes can increase the strength and stability of structures so that they can withstand external forces.
7-3-08     Describe, using diagrams, how common structural shapes and components
                can increase the strength and stability of a structure
7-3-09     Describe and demonstrate methods to increase the strength of materials.
7-3-10     Determine the efficiency of a structure by comparing its mass with the
                mass of the load it supports.
7-3-11     Evaluate a structure to determine the appropriateness of its design, using
                the design process.
7-3-12     Use the design process to construct a structure that will withstand the
                application of an external force.

     In addition to hard-copy resources I have available in the school and from colleagues, I also started to organize some online resources to supplement our classroom activities. Here are the resources I found, organized by the themes I stated above. For each one I've included the title, a very brief point about what it includes, and the link.
