Mechanics Levers & Linkages
Students can construct up to 16 models!
Discover how to increase applied force or change the direction of motion with levers! From a seesaw and wheelbarrow to a parking gate and an extendable arm, students build 16 working models to witness levers in action. They discover the relationship between the fulcrum, effort, and load through hands-on learning. Students also create examples of the three classes of levers and learn how linking them together creates complex motion. An easy-to-follow booklet guides them through the process and provides a detailed explanation of the scientific principles applied. Kit includes 106 pieces. Full contents list online.

student’s life! From the wheels on a bike to the mechanism inside door knobs, students discover how wheels and axels use friction to easily move objects. They also find out how the size of a wheel impacts movement. As lessons progress, students experiment with force using inclined planes at various degrees and see how wedges are convenient tools for everyday life. Step-by-step instruction guides students through the building process of 14 models and explain their relationship to certain scientific principles. Kit includes 134 pieces. Full contents list online.

Mechanics Pulley Drives
Hands-on experiments show students how a simple pulley drives complex machines! Pulleys serve as a key component of many machines, lifting loads big and small.
Students can construct up to 8 models!
Complete Set
Students see firsthand how to use a pulley to transfer force or increase speed while building 8 machines. They start with a simple material lift pulley or stationary bike, and then move on to more complex pulley systems including a crane bridge and a windmill. Demonstrations also show students how the pulley’s size affects the amount of force and speed produced. Included guide is easy to follow and features detailed explanations and quizzes about the experiments. Kit includes 108 pieces. Full contents list online.
