Conservation.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
What You'll Learn
The three are ranked, not equal. Reducing avoids the material entirely, reusing avoids reprocessing, and recycling still costs energy and loses quality each cycle. Treating recycling as the first answer misses the two larger savings.

Steps
Read the explanation above and note the two key terms before you start.
Audit one day of your household's waste by category and mass. For the three largest categories, write one realistic reduce action, one reuse action and one recycle action, then rank them by mass saved.
Record what actually happened, including anything that did not match what you expected.
Write a conclusion that answers the question this lesson opened with, and state your uncertainty.
