Fifth Graders' Learning About Simple Machines Tjrough Engineering Design-Based Instruction Using Lego Materials

This article's aim is to focus on the impact of the unit on student's content understanding of simple machines. The LEGO engineering-based simple machines module was implemented for fifth grade students and they showed significant growth in content understanding.
In this activities students should learn how to analyze situations and gather relevant information, define problems, generate and evaluate creative ideas, develop their ideas into tangible solutions, and assess and improve their solutions. Engineering design activities allow student to learn both design procedures and science content. Gaining a conceptual understanding of simple machines” is important for elementary studentsbecause simplemachines are everywhere in our daily lives and also it is a standard curriculum unit taught in many school systems
