FREE Carbon Cycle Video & Worksheet | Biology & Earth Science
Are you teaching the Carbon cycle in your science class? Then we have you covered!
Why This Carbon Cycle Video Works ♻️
We've seen firsthand that most carbon cycle instruction treats it as pure memorization: plants take in CO₂, animals release it, decomposers recycle it. That's technically accurate, but missing the huge impact. Why does this cycle matter? How do we know it's out of balance? What does biology have to do with climate change? These are the questions your students are going to wrestle with.
Our video answers these questions by following carbon through actual reservoirs and quantifying real fluxes. Students learn that photosynthesis captures 120 gigatons of carbon annually—but cellular respiration and decomposition release nearly the same amount back. In a balanced system, these inputs and outputs match. They'll also explore how humans have impacted this and caused things to go out of balance.
🎯 Standards Covered:
NGSS standard
- HS-LS2-5, using mathematical representations to support explanations of carbon cycling in ecosystems.
TEKS Addressed:
- Middle School Science: 8.11.C - describing how carbon cycles throughout Earth.
- High School Science: BIO.13.C - explain the significance of the carbon and nitrogen cycle to ecosystem stability and analyze the consequences of disrupting these cycles
What the video covers:
✅ How carbon cycles through Earth's major reservoirs: atmosphere, biosphere, hydrosphere, geosphere
✅ Photosynthesis capturing atmospheric CO₂ and storing it in organic molecules
✅ Cellular respiration releasing carbon back to the atmosphere
✅ The role of decomposition in recycling carbon from dead organisms
✅ Long-term carbon storage in fossil fuels and carbonate rocks
✅ How human activities are altering the carbon cycle
✅ Mathematical modeling of carbon flows between reservoirs
The Free Student Worksheet
The accompanying worksheet includes 10 questions ranging from basic recall to higher-order analysis and application. Students calculate residence times, compare GPP and NPP, explain decomposition factors, analyze human impacts, and propose practical solutions at both individual and policy levels. Question 10 is particularly valuable too for formative assessment!
Building Your Complete Biogeochemical Cycles Unit 🌎
This carbon cycle video works beautifully alongside our other biogeochemical cycle resources to create comprehensive understanding of Earth's systems:
🥼 Carbon Cycle Lab Stations
Provide hands-on exploration of carbon storage, release, and cycling through six investigation stations. Students model photosynthesis and respiration, investigate decomposition rates, explore fossil fuel formation, and analyze human impacts—perfect for kinesthetic learning and collaborative investigation.
📖 Carbon Reading Articles
Connect carbon cycle concepts to everyday experiences while building scientific literacy. These work excellently for homework, bell-ringers, or differentiated instruction.
🥼 Nitrogen Cycle Lab Stations
Complete the biogeochemical trilogy, helping students understand how essential elements cycle through ecosystems differently based on their chemical properties and biological roles.
💧Water Cycle Resources
Easily complement carbon cycle instruction by showing how multiple biogeochemical cycles interact. Our free water cycle video, lab stations, and anchoring phenomena activities help students understand Earth systems holistically rather than as isolated concepts.
Together, these resources build systems thinking—students recognize patterns across cycles while appreciating each element's unique characteristics.

Use the video as an engaging introduction to your carbon cycle unit, a comprehensive review before assessments, or a substitute day lesson that actually teaches. The worksheet works for individual completion during viewing, partner discussion afterward, or homework reinforcement.
Question 10 makes an excellent formative assessment. You'll immediately see which students grasp the complete cycle and it's impacts and which may need additional support or intervention.
