Specific Learning Objectives: By the end of this project, students will be able to:
Mechanical Advantage:
Explain how the lever arm on the mousetrap affects the force and distance over which the string is pulled.
Analyze how wheel diameter relates to the distance covered per rotation and the required torque.
Discuss how different axle configurations (e.g., direct drive vs. geared) can provide a form of mechanical advantage in terms of speed or force.
Quantify the trade-offs between force/torque and displacement/speed in their design choices.
Problem-Solving & Critical Thinking:
Identify and analyze the factors limiting the performance of their mousetrap car (e.g., friction, energy loss, design flaws).
Develop and test different design solutions to overcome these limitations.
Critically evaluate the effectiveness of their design choices based on experimental data and theoretical understanding.
Apply iterative design principles to refine their car for optimal performance.
Engineering Design & Analysis:
Develop detailed design plans, including sketches or CAD drawings, outlining the car's components and dimensions.
Select appropriate materials based on their properties (e.g., strength, weight, friction).
Perform calculations related to potential energy storage in the mousetrap, work done, and energy losses due to friction.
Analyze the motion of the car (e.g., acceleration, velocity, distance) using kinematic principles.
Communication:
Clearly communicate their design process, analysis, and results through written reports and oral presentations.
