Quest: GoKart

Quest: GoKart [∞]

Here’s a three-week Choice Quest focused on building a Go-Kart, assuming the frame is already welded. This quest will guide students through the process of assembling, testing, and fine-tuning the Go-Kart, focusing on the drivetrain, steering system, brakes, and safety.

Week 1: Drivetrain Assembly and Engine Installation

Objective: Students will install the engine, connect the drivetrain, and ensure that the engine is properly mounted and aligned with the wheels.

1. Exploration Tasks:
   • Watch a video on Go-Kart drivetrain assembly, including the components needed (engine, transmission, chain/sprockets, etc.) and their roles in the Go-Kart's performance.
   • Read about engine types commonly used in Go-Karts, such as single-cylinder engines, and the basic principles of power transmission.
   • Learn how to mount and align the engine with the rear axle to ensure proper chain tension and sprocket alignment.
2. Choice Activities:
   • Hands-On: Mount the engine onto the Go-Kart frame, ensuring that the engine is securely attached and aligned with the rear axle. Install the clutch and chain, connecting the engine to the rear axle sprocket.
   • Creative: Create a diagram that illustrates how the drivetrain system works, from the engine to the rear wheels.
   • Research: Explore the different types of Go-Kart engines available and decide on which one might be the best fit for the desired performance.
3. Reflection:
   • Reflect on how the engine and drivetrain components are connected and how this will affect the Go-Kart's speed and handling.

Week 2: Steering and Suspension Systems

Objective: Students will install the steering system, including the steering wheel, tie rods, and front axle, ensuring smooth and responsive handling.

1. Exploration Tasks:
   • Watch a video on Go-Kart steering systems, covering the installation of the steering wheel, steering column, and linkages, as well as tie rods and the front axle.
   • Read about different types of steering systems (e.g., rack and pinion vs. direct link) and how they affect handling.
   • Learn about suspension options for Go-Karts, such as using springs or shock absorbers for the front and rear axles to improve ride quality.
2. Choice Activities:
   • Hands-On: Install the steering column, wheel, and linkages, ensuring that the steering system operates smoothly. Connect the tie rods to the front axle and make sure the wheels are aligned for proper tracking.
   • Creative: Design and build a simple front suspension system for the Go-Kart to improve handling and comfort, if applicable.
   • Research: Investigate how different Go-Kart steering systems impact the driving experience, and choose one that fits the goals for the project.
3. Reflection:
   • Reflect on the steering system's functionality, how alignment and tightness affect handling, and the importance of a responsive steering mechanism for safety.

Week 3: Brakes, Safety Features, and Final Testing

Objective: Students will install the braking system, add safety features (e.g., seatbelts, roll bars), and conduct final tests to ensure everything is functioning properly.

1. Exploration Tasks:
   • Watch a video on Go-Kart brake systems, covering the installation of disc or drum brakes, as well as how to adjust them for maximum effectiveness.
   • Read about Go-Kart safety features, such as installing a roll bar, seatbelt, and protective padding to minimize injury risks.
   • Learn how to perform a safety inspection on the completed Go-Kart, ensuring that all systems are secure and functional before driving.
2. Choice Activities:
   • Hands-On: Install the brake system, ensuring that it is correctly connected to the rear axle and that the brakes are responsive. Adjust the brake lines and test for proper operation.
   • Hands-On: Add any safety features, including a seatbelt, roll bar, and padding around the driver’s area. Ensure that all components are securely attached.
   • Testing: Perform a series of tests to check the Go-Kart's performance, such as acceleration, handling, and braking. Make any necessary adjustments to improve performance.
3. Reflection:
   • Reflect on the importance of safety features in Go-Karts and the challenges faced when setting up the braking system. Discuss how testing and adjustments improve the overall performance and safety of the Go-Kart.

Final Project: Go-Kart Presentation and Test Drive

Objective: Students will complete the Go-Kart, make final adjustments, and present their work, demonstrating the functionality of the Go-Kart.

1. Exploration Tasks:
   • Review the entire process of Go-Kart construction, from drivetrain assembly to safety features.
   • Research proper Go-Kart maintenance and tips for improving performance over time.
2. Choice Activities:
   • Hands-On: Complete any remaining adjustments or fine-tuning needed to ensure the Go-Kart runs smoothly.
   • Creative: Create a video or presentation showcasing the construction process, including the challenges faced and how they were solved. Highlight the performance tests and final results.
3. Reflection:
   • Reflect on the overall project, including the design choices, challenges overcome, and the knowledge gained from building the Go-Kart.
