**What This Document Is**
This document is a student exploration sheet—a Gizmo—designed to accompany a simulation of the carbon cycle. Developed for a Molecular Biology course (BP 723) at Harvard University, it guides students through interactive exploration of how carbon atoms move between Earth’s various systems: the atmosphere, biosphere, hydrosphere, and geosphere. It focuses on identifying carbon reservoirs and pathways, and understanding the impact of processes like photosynthesis, respiration, and geological activity.
**Why This Document Matters**
This Gizmo and accompanying worksheet are valuable for students learning about biogeochemical cycles, a core concept in molecular biology, environmental science, and related fields. It’s used as an introductory or reinforcing activity to visualize and understand the complex interactions that govern carbon distribution on Earth. Understanding the carbon cycle is crucial for comprehending climate change, ecosystem dynamics, and the interconnectedness of life. This resource is particularly useful for students who benefit from visual and interactive learning.
**Common Limitations or Challenges**
This Gizmo provides a simplified model of the carbon cycle. It doesn’t encompass the full complexity of all carbon interactions, such as the role of specific enzymes or detailed chemical reactions. It serves as a foundational tool, and further study will be needed to grasp the nuances of carbon cycling in real-world ecosystems. The Gizmo itself is an interactive simulation; this document is a worksheet to guide that interaction.
**What This Document Provides**
This document includes:
* Vocabulary related to the carbon cycle (atmosphere, biomass, carbon reservoir, etc.).
* Prior knowledge questions to assess initial understanding.
* Guided exploration questions for the Gizmo simulation, prompting students to trace carbon pathways.
* A framework for identifying the Earth systems involved in each carbon transfer.
* A sample carbon path, completed as an example.
* Sections for students to record their own explorations of different carbon pathways.
This preview *does not* include the full interactive Gizmo simulation, the complete set of exploration questions, or the answers to those questions. It provides a glimpse into the structure and focus of the learning activity.
