Wind and load safety is the focus of this Grade 7 Science resource on forces, structures, and motion. Students evaluate how forces, machine function, and structural design work together when comparing design options under realistic conditions involving wind, snow, and loads.

What Students Explore

The resource develops integrated systems analysis by connecting forces, motion, machine function, and structure safety. Students use simple quantitative ideas such as mechanical advantage and load distribution to compare competing designs, then justify design choices using motion data and structural performance criteria.

Tasks include multiple-choice questions, true/false questions, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” section. The varied formats give students opportunities to identify relationships, apply quantitative ideas, interpret design conditions, and communicate evidence-based reasoning.

What You Receive

• ✅ Student worksheet focused on integrated design for wind and load safety
• ✅ Student Notes & Lesson Summary supplement for reinforcing key ideas
• ✅ Separate Teacher Guide with learning objectives, teaching tips, discussion questions, and common mistakes

Classroom Use

Use this forces and structures worksheet as guided classroom practice, independent work, a lesson reinforcement activity, or a review of design and safety concepts. The reading and response tasks can support discussion, while the quantitative comparison and design-justification questions provide opportunities for students to apply concepts to realistic structural conditions.

Why It Supports Instruction

This resource moves beyond isolated definitions by asking students to connect mechanical advantage, load distribution, motion data, and structural performance when evaluating designs. The included lesson supplement supports student preparation, while the separate teacher guide provides practical instructional support through objectives, teaching tips, discussion prompts, and common-mistake guidance. The resource is identified for the Alberta framework.
