Renewable vs Non-Renewable Resources Explored
We are learning to: Compare renewable and non-renewable resources Explain how rates of replenishment affect sustainability Use models to simulate resource extraction Record and organize investigation results
Learning Intention
Compare renewable and non-renewable resources Explain how rates of replenishment affect sustainability Use models to simulate resource extraction Record and organize investigation results Success Criteria I can tell the difference between renewable and non-renewable resources I can explain why replenishment rate matters for sustainability I can use a model to show resource extraction I can record results clearly and in order
Hook
Look at these two objects: Which could represent a renewable resource? Which could represent a non-renewable resource? What happens if we keep taking from both?
Renewable vs Non-Renewable Resources
{"left":"Renewable Resources\nReplenished naturally within human lifetime\nExamples: water, sunlight, wind, timber\nCan be used sustainably with proper management","right":"Non-Renewable Resources\nExist in limited amounts\nNot replaced quickly (millions of years)\nExamples: coal, oil, natural gas, minerals"}
Investigation Setup
{"left":"Sponge Model = Renewable Resource (water)\nSqueeze sponge → extract water → measure volume\nLet sponge reabsorb water for 30 seconds\nRepeat 3 cycles","right":"Marble Model = Non-Renewable Resource\nCollect marbles from bowl in 30 seconds\nNo refilling allowed\nRepeat 3 trials"}
What Did We Discover?
Sponge (renewable) maintained water extraction capacity Marbles (non-renewable) decreased with each trial Renewable resources can be replenished Non-renewable resources become depleted This shows why renewable resources are more sustainable
Key Takeaway
'Renewable resources are generally more sustainable because they can be replenished naturally, while non-renewable resources become depleted over time and cannot be easily replaced.'
