The "Warm Ears, Warm Hearts Challenge"

Day 4 
Challenge Overview: The "Warm Ears, Warm Hearts Challenge" is an engineering design challenge focused on creating affordable, sustainable, and effective earmuffs for those in need during cold winters. This challenge is highly relevant in today's world, addressing the needs of vulnerable communities while promoting sustainable practices and empathy among young learners.
Challenge Statement: Participants are tasked with designing and creating earmuffs that are cost-effective, durable, and made from sustainable materials. These earmuffs should be easily replicable so that they can be made by anyone and distributed to those who need them most during the winter months.
Background/Scenario: In many regions, winters can be harsh, and not everyone has access to appropriate winter gear. This challenge encourages participants to think about how they can make a difference in their communities by designing earmuffs that are both affordable and sustainable. The goal is to provide warmth and comfort to those who face the cold without adequate protection.
Children's Book Connection: This challenge is inspired by the book "The Snowy Day" by Ezra Jack Keats, which depicts a child experiencing the joys and challenges of a snowy day. This book can serve as a reminder of the beauty of winter as well as the importance of staying warm and safe during the cold months.
Challenge Categories:

1. Material Innovation: Use sustainable, recycled, or easily accessible materials.
2. Cost-Effectiveness: Focus on designs that are affordable to produce in large quantities.
3. Comfort and Durability: Ensure the earmuffs are comfortable to wear and durable.
4. Ease of Replication: Design earmuffs that can be easily made by people with basic crafting skills.

Submission Guidelines:

• Participants must submit a detailed report explaining their design process, choice of materials, and instructions for making the earmuffs.
• Include a prototype or a detailed diagram of the earmuffs.
• Use only materials that are sustainable, recycled, or easily accessible.
• Provide a cost analysis to demonstrate the affordability of the design.

Judging Criteria:

1. Sustainability and Accessibility of Materials: Use of eco-friendly and easily available materials.
2. Cost-Effectiveness: Affordability of the design for widespread production and distribution.
3. Functionality: Effectiveness in providing warmth and comfort.
4. Ease of Replication: Simplicity of the design for DIY replication.
5. Innovation and Creativity: Originality and effectiveness of the design solution.

NGSS Standards Connection:This challenge aligns with the following Next Generation Science Standards (NGSS):

• K-2-ETS1-2: Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
• 3-5-ETS1-3: Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
• MS-ETS1-2: Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
