Learning Objectives:
- Enhance 3D modeling skills with advanced tools in TinkerCad.
- Introduce precision measurement and its importance in design.
- Encourage practical problem-solving by designing replacement parts.
- Foster iterative design through testing and refining models.
- Promote collaboration and communication through group projects.
Overview of the Course:
- Advanced Modeling and Precision Measurement:
- Students use advanced TinkerCad features and learn to apply precise measurements to their designs.
- Practical Problem-Solving and Iteration:
- They design and print replacement parts for everyday items, testing and refining their models based on real-world applications.
- Enhancing Learning Environments:
- Collaborative projects focus on designing objects to improve their MeasureLab or Robotics Lab, reinforcing the impact of design on their surroundings.
Session 1: “Reimagining Everyday Objects”
Description:
Students are introduced to the concept of designing solutions for everyday problems. The teacher presents examples of simple objects that enhance daily life (e.g., a custom bookmark, a unique key holder). The class discusses how designers identify problems and create objects to solve them. This session sets the stage for thinking about practical applications of their designs.
Session 2: “Discovering TinkerCad Tools: Advanced Shapes and Features”
Description:
Students explore more advanced tools in TinkerCad, such as scribble (freehand drawing), shape generators, and importing images. The teacher demonstrates how to combine these tools to create more complex designs. Students practice by creating a simple object that incorporates these new features, such as a personalized nameplate with decorative elements.
Session 3: “Fix It Fun: Designing Replacement Parts”
Description:
Students are encouraged to think about items they have at home that might be broken or missing a piece (e.g., a lost game token, a missing puzzle piece, a broken toy part). They discuss how they could design a replacement part. In class, they choose a simple item to recreate or improve upon in TinkerCad, learning how to take measurements and apply them to their designs.
Session 4: “Measuring and Modeling: Precision Matters”
Description:
The teacher introduces basic measurement techniques using rulers and calipers. Students learn how to measure objects accurately and input dimensions into TinkerCad. They revisit their replacement part designs, refining them based on precise measurements to ensure a proper fit and function.
Session 5: “Printing Solutions: Bringing Designs to Life”
Description:
Students prepare their finalized replacement part designs for printing. The teacher guides them through checking their models for printability, such as ensuring correct dimensions and avoiding unsupported overhangs. Students watch as their designs are printed, reinforcing the link between accurate modeling and successful physical outcomes.
Session 6: “Testing and Iteration: Does It Fit?”
Description:
With their printed parts ready, students test them with the original items (if possible). They assess whether their parts fit or function as intended. If adjustments are needed, they note the changes required. The teacher emphasizes the engineering process of testing, evaluating, and iterating designs to improve them.
Session 7: “Enhancing Our Labs: Designing for MeasureLab and Robotics Lab”
Description:
Students brainstorm items that could enhance their experience in the MeasureLab or Robotics Lab. Ideas might include a holder for sensors, a customized casing for a robot, or an organizer for lab accessories. They select a project and begin designing it in TinkerCad, considering functionality and user needs.
Session 8: “Group Collaboration: Building Complex Structures”
Description:
Students form small groups to work on a collaborative project related to the labs. For example, one group might design a modular storage system, while another creates interchangeable parts for a robot. They learn to divide tasks, share ideas, and integrate different components into a cohesive design.
Session 9: “Finalizing and Printing Group Projects”
Description:
Groups finalize their designs, ensuring all parts are compatible and functional. The teacher assists with preparing the files for printing, discussing considerations like print orientation and support structures. Students observe the printing process and begin thinking about assembly and testing.
Session 10: “Showcase and Reflect: Our Designs in Action”
Description:
Students present their individual and group projects to the class (and possibly other classes or parents). They demonstrate how their designs solve a problem or enhance the labs. The session includes reflections on what they learned about the design process, challenges faced, and how they overcame them. The teacher encourages discussion on the importance of perseverance and creativity in problem-solving.
