Simple Machines: Advanced
These sites include interactive models of machines such as levers and pulley systems. Explains the basic concepts of physics such as mechanics, gravity, effort, resistance, work, torque, friction, and motion. Includes lesson plans, laboratory exercises, and experiments. There are links to eThemes resources on simple machines for beginners and compound machines.
Exploratorium: Hands Up! Rock Climbing: Levers and Wedges
This site documents a climb and explains some of the physics and forces involved. The pages are mostly text with a few images, but it may be an interesting way to get students to think about the ways they move as principles of physics.
Mechanical Advantage: Pulley System
This diagram shows the relationships and mechanical advantage within a simple pulley system.
Leonardo da Vinci: Mysterious Machinery

ThinkQuest: Visual Physics
Learn about "force", "work", and "torque" by clicking on the left. Very advanced vocabulary.
Dirtmeister's Simple Machines
Once you know about the simple machines, come to this site for forms to fill out for observing a simple machine and writing a report. You can read sample reports from students.
Simple Machines: Information Sheet
Read about physical forces and simple machines and their mechanical advantages.
How Stuff Works: How a Block and Tackle Works
This site illustrates and explains how a system of pulleys and rope can help get work done. NOTE: The site includes ads.
Classroom Activity: Be Inventive!
Use your imagination and create a simple machine. The in class activity involve student working in groups to design, sketch, and build a working prototype of a machine.
Simple Machines: A Lesson Plan
This lesson is designed for fourth-eight graders. During the lesson kids will take apart broken toys and construct new working machines.
Science NetLinks: Systems 1: Simple Machines
In this lesson plan, students will gain understanding of the interactions between different parts of a system and engage in troubleshooting and design related to systems. NOTE: This site has links to external sites.
Identify the Simple Machine 2
Identify simple machines found in more complex machines.
eThemes Resource: Simple Machines: Beginner
