Student Instructions

Welcome, future engineers! Over the next few lessons, we will be exploring the six classic simple machines. These are the fundamental mechanical devices that allow us to multiply force or change the direction of force, making difficult tasks much easier. From opening a door (lever) to lifting a heavy flag (pulley), these concepts are the basis of all complex machinery we use every day. Your goal is to become an expert on how these machines work, what they look like, and how they impact our lives. Phase 1: Brainstorming & Definition (Pages 1-2) 1. Research: Use a link🔗 tool or search engine to find a solid definition of a simple machine. 2. Text Box: Write the definition in your own words. 3. Voice Recording: Record yourself explaining why simple machines are important (e.g., "They reduce the amount of effort needed..."). Phase 2: Deeper Research - The Six Machines (Pages 3-8) For each page in this phase, you must include a definition, three distinct examples, and a visual element (picture or drawing). 1. Definition: Use a text box for the definition. 2. Examples: List and briefly describe three examples of different classes of levers (e.g., first-class: seesaw, second-class: wheelbarrow, third-class: fishing rod). 3. Picture: Use the photo tool or drawing tool to include an image of a lever in action. Phase 3: The Simple Machines Quiz (Pages 9-15) The final seven pages will be your quiz designed to test your learning. When completed check .
