Standards

Math

7.MP.4 Model with mathematics.

Mathematically proficient students apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. When given a problem in a contextual situation, they identify the mathematical elements of a situation and create a mathematical model that represents those mathematical elements and the relationships among them. Mathematically proficient students use their model to analyze the relationships and draw conclusions. They interpret their mathematical results in the context of the situation and reflect on whether the results make sense, possibly improving the model if it has not served its purpose

Intro/Driving Question/Opening

This lesson will embark on an exploration of creativity, sustainability, and innovation through the art of upcycling empty water bottles. In this session, we will discover the transformative power of repurposing everyday materials as we turn ordinary plastic bottles into beautiful and functional creations.

Water bottles, ubiquitous in our daily lives, often end up in landfills, contributing to environmental pollution and waste. However, today, we will challenge ourselves to see these bottles not as disposable items but as valuable resources with the potential for new life and purpose. Through the process of upcycling, we will breathe new life into these bottles, giving them a second chance to shine.

In this lesson, we will explore the science behind plastic materials, understanding their properties and environmental impact. We will then apply engineering principles to design and build innovative projects using empty water bottles as the primary material. From artistic decorations to practical solutions, the possibilities are endless as we unleash our creativity and problem-solving skills.

But that's not all – we will also leverage technology to seek inspiration from online resources, discovering a wealth of ideas and designs that showcase the versatility of upcycled materials. And as we dive into the creative process, we will apply mathematical concepts to make precise measurements, calculate materials, and ensure the structural integrity of our creations.

By the end of this lesson, you will not only have created unique and sustainable projects but also gained a deeper understanding of the importance of environmental stewardship and the role that each of us can play in reducing waste and protecting our planet. So let's roll up our sleeves, ignite our imaginations, and embark on this exciting journey of upcycling empty water bottles!

Hands-on Activity Instructions

Day 1: Exploring Materials and Design Inspiration

Begin the lesson with a discussion on the importance of upcycling and the environmental benefits of reusing materials like empty water bottles.
Introduce students to various types of Christmas decorations that can be made using water bottles, such as snowflakes, ornaments, or wreaths.
Use multimedia resources or online presentations to showcase examples of upcycled Christmas decorations made from recycled materials, including water bottles.
Engage students in a brainstorming session to generate ideas for their own Christmas decoration projects using empty water bottles, encouraging creativity and innovation.
Assign students to research and gather design inspiration from online sources, such as DIY crafting websites or social media platforms, and save images or sketches of their chosen designs for reference.

Day 2: Engineering and Prototyping

Review the design ideas and inspiration gathered by students from the previous day's activities.
Introduce the engineering challenge: designing and building a prototype of a Christmas decoration using empty water bottles as the primary material. Provide students with design constraints and criteria for their prototypes (e.g., must incorporate at least three water bottles, should be durable and aesthetically pleasing).
Divide students into small groups and allow them time to sketch and plan their decoration designs, considering factors such as structure, color, and decoration techniques.
Provide prototyping materials and supervise students as they build their decoration prototypes, offering guidance and support as needed.
Encourage students to test their prototypes and make adjustments as necessary to improve functionality and appearance.

Day 3: Math Applications and Presentation

Begin the lesson with a review of the engineering design process and students' progress on their decoration prototypes.
Introduce mathematical concepts related to measurements and calculations needed for the decoration project, such as determining dimensions, calculating surface areas, and estimating materials required.
Engage students in hands-on math activities, such as measuring the dimensions of water bottles and calculating the amount of decorative materials needed for their projects.
Have students finalize their Christmas decoration projects, incorporating any additional decorations or embellishments.
Allow time for students to present their decoration projects to the class, explaining their design process, materials used, and the significance of upcycling in their creations.
Encourage peer feedback and reflection on the STEM integration in the Christmas decor project, highlighting connections between science, technology, engineering, and math concepts.

Differentiation

Multiple Entry Points: Offer students a choice of project options based on their interests and abilities. Some students may prefer artistic projects like creating sculptures or decorations, while others may be more interested in functional designs like organizers or planters.
Varied Materials: Provide a range of materials beyond just empty water bottles, such as additional recyclable items (e.g., cardboard, paper, plastic containers) or alternative crafting materials (e.g., fabric, wood). This allows students with different preferences and skill levels to choose materials that best suit their strengths and interests.
Flexible Grouping: Allow students to work independently or in small groups based on their comfort level and collaboration preferences. For example, students who may struggle with group work can be paired with a peer mentor for support, while those who excel in teamwork can collaborate on more complex projects together.
Modified Instructions: Break down instructions into smaller, more manageable steps, and provide visual aids or written guides to support students who may have difficulty processing verbal instructions. Offer additional demonstrations or hands-on support as needed to ensure that all students understand the tasks and expectations.

Extension/Enrichment

Organize a holiday craft fair or exhibition to showcase students' Christmas decoration projects and raise awareness about upcycling and environmental sustainability.
Collaborate with the Art or English/Language Arts teacher to create written reflections or artist statements accompanying students' decoration projects, exploring themes of creativity, conservation, and community engagement.
Invite guest speakers from local recycling centers or environmental organizations to share insights and initiatives on waste reduction and upcycling practices.
