Pulleys: Changing Direction and Force
Students will investigate how single and multiple pulley systems can change the direction of force and reduce effort.
Key Questions
- Explain how a pulley system can make lifting heavy objects easier.
- Compare the mechanical advantage of a single fixed pulley versus a movable pulley.
- Construct a pulley system to solve a specific lifting challenge.

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.

Introduction to Forces
Students will identify different types of forces (push, pull, gravity, friction) and their effects on objects.
3 methodologies
Measuring Force and Motion
Students will use tools to measure force and observe how forces cause changes in motion.
