The Science of the Three Rs
Earth Day Unit // Lesson 01
The Global "Gulp"
The average person generates 4.9 pounds of trash every single day.
Globally, we produce 2.01 billion tons of municipal solid waste annually.

Science Fact: Microplastics never fully disappear; they just get smaller and smaller.
The 3 Rs: A Hierarchy
01
Reduce
The most effective way! Don't create the waste in the first place.
02
Reuse
Find a new purpose for an item before tossing it. Think "Upcycling"!
03
Recycle
A chemical or mechanical process to turn old materials into new ones.
The Infinite Loop

Did you know? Aluminum can be recycled forever without losing quality!
Mission: Plastic Path
Today, we aren't just consumers. We are analysts. Grab your "Plastic Path Lab" sheet and let's track the footprint of a single lunch.

The Reduction Roadmap
Based on your audit, which item in your lunch is the "Biggest Offender" (environmentally)?
How could you REDUCE or REUSE this item instead of throwing it away?
Reflection: Why is "Reducing" considered more effective than "Recycling" in the waste hierarchy? Think about the energy and water used in the recycling process.

Duration
3-4 Class Periods (200+ mins)
Core Standards
MS-ESS3-3: Earth & Human Activity / MS-PS1-3: Properties of Matter
Preparation Checklist
Trash Samples: Collect 2 sets of samples: clean lunch waste for audits and mixed samples (organic/inorganic) for the decomposition jars.Microplastic Lab: Prepare "Shoreline Samples" by mixing play sand with finely cut-up plastic bag pieces and colorful glitter (to simulate microplastics).Decomposition Jars: Set up jars 1 week in advance if you want students to see immediate results, or start them Day 1 for a 2-week observation project.
Instructional Flow
Day 1 The Audit & The Hierarchy (50 mins)
Introduce the "Waste Warriors Slides". Complete the "Plastic Path Lab Worksheet" to audit consumption. Key Goal: Connect individual actions to global waste data.
Day 2 The Breakdown Experiment (50 mins)
Distribute "The Great Break Down Lab". Students set up their jars and record initial hypotheses. Discuss the role of moisture and oxygen in decomposition. This becomes a recurring "Fast Five" observation every 2 days.
Day 3 Microplastic Hunt (50 mins)
Distribute "Microplastic Hunt Lab". Focus on physical properties: density and size. Explain how microplastics enter the food chain through aquatic life. Use the reflection to lead into Lesson 2 (Art).
Experimental Tips
Microplastic Separation: Use warm water to help some plastics float more easily. Ensure students stir long enough to free plastic pieces from the sand's surface tension.
Odor Control: For the "Great Break Down" jars, ensure the lids are tight but check them regularly for mold growth. If smells become an issue, move jars to a ventilated area or a science prep room.

Scientific Conclusion
1. Which items showed signs of decomposition? What physical changes did you observe?
2. How does the lack of oxygen in a real landfill (packed tight) slow this process down compared to your jar?

The Hidden Danger
Microplastics are tiny pieces of plastic less than 5mm in size. They often enter our waterways through clothes (synthetic fibers), personal care products, and the breakdown of larger litter. In this lab, you will use density to separate microplastics from a "shoreline" sample.
Material List
Shoreline Sample (Sand/Dirt)
Clear Beaker (250mL)
Stirring Rod
Sieve or Coffee Filter
Procedure
Fill your beaker halfway with the shoreline sample.
Slowly add water until the beaker is 3/4 full.
Stir the mixture vigorously for 60 seconds.
Wait for 3 minutes. Observe what sinks and what floats.
Skim the top layer through the coffee filter.
Sketch your Beaker (Side View)
Label the layers: Sand, Water, Floating Plastics
Investigation Results
1. Describe the particles you caught in the filter. (Color, shape, texture)
2. Why did the plastic float while the sand sank? (Density Connection)
Critical Challenge
If these plastics float in the ocean, which marine animals are most likely to accidentally eat them?

The Art of Upcycling
Earth Day Unit // Lesson 02
Recycling vs. Upcycling
Recycling
Breaking down a material (melting, shredding) to make something new but similar.
Example: A soda can becomes a new soda can.
Upcycling
Reusing an object in a way that increases its value or function.
Example: A soda can becomes a desk lamp.

Your Creative Process
1
IDENTIFY
Find a piece of "trash" with interesting shapes/colors.
2
IMAGINE
Sketch out how it can transform into something new.
3
ITERATE
Build, test, and tweak your design.
4
IMPACT
Present your work and explain its environmental value.
The Upcycle Challenge
"One person's trash is another student's masterpiece."
Mission Parameters:
Use at least 75% discarded/waste material.
Must serve a new function OR tell an environmental story.
Must be structurally stable (won't fall apart!).

Project Prep & Safety
Safety Check: Ensure all waste items are cleaned and free of sharp edges (sand down sharp can lids if necessary). No biological waste or chemicals.Tool Station: Set up a "Connector Hub" with hot glue guns (supervised), duct tape, wire, and heavy-duty scissors or box cutters (teacher-only use suggested for thick plastics).
Instructional Flow
1. Inspiration: The Garbage Gallery (10 mins)
Project "Trash to Treasure Slides". Highlight the difference between recycling and upcycling. Emphasize that upcycling is a value-add process.
2. Design Phase: Blueprints (15 mins)
Students use the "Upcycle Challenge Guide" to sketch their ideas. Circulate and ask: "How will you connect these two materials? Is it structurally sound?"
3. Build: The Makerspace (45-60 mins)
Provide building time. Encourage students to pivot if their first idea doesn't work—this is part of the engineering design process.
4. Exhibit: Artist Statements (20 mins)
Students fill out the "Eco-Artist Statement". Organize a "Gallery Walk" where students leave their statements next to their art for others to read.
Reflective Discussion Prompts
"Which was harder: the scientific audit or the artistic transformation? Why?"
"How did your perception of 'trash' change during this project?"
"If we can upcycle items, why is 'Reducing' still the first 'R' in the hierarchy?"
