Halloween Candy Sustainability Investigation – Environmental Science October

Turn Halloween candy into meaningful environmental science! In this Candy Sustainability Investigation, students uncover the hidden environmental footprint of candy as they explore cocoa production, palm oil, packaging waste, and transportation.

Students analyze evidence, complete calculations, evaluate sustainability trade-offs, and compare environmental impacts before taking on a Sustainable Candy Challenge. They’ll redesign a Halloween candy to reduce its environmental footprint while considering real-world factors like cost, food safety, freshness, and transportation. The activity wraps up with a Claim, Evidence, and Reasoning (CER) response.

Students Will Explore:

• Cocoa Production – Compare farming practices, biodiversity, and agroforestry
• Palm Oil – Evaluate sourcing options, land use, and habitat impacts
• Packaging Waste – Calculate candy wrapper waste and compare packaging solutions
• Candy Miles – Calculate supply-chain distances and analyze transportation impacts
• Sustainability Scorecard – Compare the environmental impacts of candy production
• Sustainable Candy Challenge – Design a more sustainable candy and consider trade-offs
• Final CER – Use evidence to determine how Halloween candy could become more sustainable

What’s Included:

• Complete student investigation
• 4 sustainability investigations
• Sustainability Scorecard
• Sustainable Candy Design Challenge
• CER assessment
• Detailed Teacher Guide
• Complete Answer Key
• Differentiation & extension ideas

No actual candy is required! Candy wrappers or packages can be added as an optional real-world connection.

Perfect For:
Environmental Science • Sustainability • Human Impact • Ecology • Halloween Science • October Lessons • Seasonal Science Activities • Sub Plans

This low-prep Halloween activity gives students a seasonal hook while keeping the focus on real environmental science, critical thinking, problem-solving, and evidence-based decision-making.
