Simple Machines: Pulleys and Wheel & Axle
Students will investigate the function of pulleys and the wheel and axle, calculating their mechanical advantage.
Key Questions
- Analyze how pulley systems reduce the force required to lift objects.
- Compare the mechanical advantage of a single fixed pulley versus a movable pulley.
- Construct a system using a wheel and axle to demonstrate force multiplication.

Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
