8th Grade Scientists Explore Simple and Complex Machines Through Hands-On LEGO Engineering In Mrs. Merril and Mr. Giovingo's 8th Grade Integrated Science class, students recently embarked on an engaging exploration of simple and complex machines—one LEGO brick at a time. The lesson challenged students to apply their understanding of the six simple machines (levers, pulleys, wheels and axles, inclined planes, wedges, and screws) by designing and constructing their own complex machines using LEGO building sets. From cranes and catapults to conveyor systems and mechanical lifts, students' creativity and engineering skills were on full display. Building Knowledge Through Construction After selecting a complex machine to build, students worked individually or in small groups to bring their designs to life. The hands-on nature of the project allowed students to see firsthand how multiple simple machines work together to create more sophisticated tools and devices. "This activity really helps students understand that the complex machines we use every day—cars, bicycles, construction equipment—are all built from combinations of these basic simple machines," explained Mr. Giovingo. Analysis and Application Once construction was complete, students conducted an analysis of their creations. They identified each simple machine present in their complex machine, documented their findings in a written report, and made real world connections of complex machines they find useful in their own life. The project not only strengthened students' grasp of mechanical principles but also developed important skills in problem-solving, spatial reasoning, and technical communication. STEM in Action This lesson exemplifies Archbishop Chapelle's commitment to providing students with engaging, hands-on STEM experiences that prepare them for future success in science, technology, engineering, and mathematics fields. By combining creativity with scientific inquiry, students gain a deeper appreciation for the engineering principles that shape our world.
