Beyond Bubble Wrap: Engineering Sustainable Packaging from Local Waste

Grade 7Science5 days
In this 7th-grade science project, students tackle the global plastic crisis by engineering durable, biodegradable shipping materials from local agricultural waste or fungi. Using the engineering design process, students move from analyzing the environmental impact of conventional plastics to growing and stress-testing their own mycelium-based or fiber-composite prototypes. The experience culminates in a 'Solution Seeker’s Showcase,' where students pitch their data-backed sustainable alternatives to local stakeholders, balancing production costs with performance and ecological benefits.

Entry Events

Events that will be used to introduce the project to students

The Plastic Snowstorm Excavation

Students enter to find a massive, 6-foot mountain of non-recyclable shipping waste (bubble wrap, peanuts, plastic film) in the center of the room, with a single, fragile smartphone box buried at the very bottom. They must 'excavate' the item and calculate the 'trash-to-product ratio,' sparking a debate on why we use permanent materials for temporary protection.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Plastic Autopsy: Mapping the Lifecycle Gap

Before building a solution, students must deep-dive into the environmental 'cost' of the plastic mountain they excavated. In this activity, students compare the lifecycle of a plastic bubble mailer to a piece of organic waste (like a corn husk or mycelium). They will map out where these materials come from, how they are made, and where they end up if they are not recycled, focusing on their impact on local biodiversity.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Research the chemical origin of polyethylene (plastic) and the biological origin of a local waste product (e.g., corn husks, wheat straw, or fungi).
2. Use a 'Decomposition Timeline' to illustrate how long each material stays in the local ecosystem.
3. Identify three specific ways plastic pollution threatens local biodiversity (e.g., microplastics in local waterways).
4. Summarize why a 'Solution Seeker' is needed to intervene in this lifecycle.

Final Product

What students will submit as the final product of the activityA Comparative Lifecycle Infographic or Digital Map showing the 'Cradle-to-Grave' journey of synthetic plastic versus a natural alternative.

Activity 2

The Shield Blueprint: Setting the Design Criteria

Students transition from environmentalists to engineers. They must define exactly what their new material needs to achieve. By analyzing the 'fragile smartphone box' from the entry event, students will establish the physical criteria (strength, weight, moisture resistance) and the constraints (cost, availability of local waste, biodegradability time) that their prototype must meet.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Analyze the smartphone box: What specific protections did the plastic provide? (e.g., shock absorption, waterproof casing).
2. Create a list of 'Must-Haves' (Criteria) and 'Can't-Haves' (Constraints) for your new material.
3. Draft a technical drawing or a descriptive 'Recipe Card' for your proposed material using local agricultural waste or fungi.
4. Submit the brief for a 'Peer Design Review' to ensure the goals are precise and measurable.

The Impact Gauntlet: Stress-Testing the Prototypes

It’s time to break things! Students subject their prototypes to a series of 'stress tests' modeled after real-world shipping hazards: The Drop Test (impact), The Stack Test (pressure), and The Soak Test (moisture). They will collect quantitative data to see how their bio-material stacks up against the plastic bubble wrap.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Perform the 'Standard Drop': Drop a weighted box protected by your material from 3 different heights.
2. Perform the 'Stack Test': Measure how many pounds of pressure your material can withstand before deforming.
3. Compare your results against the data from the 'Plastic Snowstorm' materials tested in the entry event.
4. Identify the 'Failure Point' and write a 1-paragraph plan for 'Version 2.0' to improve durability.

Activity 5

The Solution Seeker’s Showcase: Waste to Wonder

In the final phase, students assume the role of sustainable entrepreneurs. They will pitch their engineered material to a panel (teachers, local business owners, or environmentalists), explaining why their local waste-based solution is a viable, cost-effective replacement for plastic. They must use their data to prove their material works and their lifecycle research to prove it’s better for the planet.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Synthesize your testing data and environmental research into a clear, persuasive narrative.
2. Calculate the 'Local Benefit': How much local agricultural waste could your solution divert from landfills?
3. Create a visual aid (slide deck or poster) that highlights the trade-offs you balanced (e.g., 'Slightly heavier than plastic, but 100% compostable').
4. Present your solution and answer 'Stakeholder Questions' about the scalability and cost of your material.

Final Product

What students will submit as the final product of the activityThe 'Solution Seeker' Pitch: A multimedia presentation or video commercial showcasing the prototype, the data, and the environmental impact.

Alignment
