**What This Document Is**
This document is a student exploration sheet designed to accompany the “Plants and Snails” Gizmo, an interactive simulation from ExploreLearning. It’s intended for use in a Molecular Biology course (BP 723) at Harvard University. The sheet guides students through a virtual experiment investigating the relationship between plants, snails, carbon dioxide, and oxygen. It focuses on observing changes in gas levels and water color as indicators of biological processes.
**Why This Document Matters**
This exploration sheet is valuable for students learning about fundamental biological concepts like photosynthesis, aerobic respiration, and the carbon dioxide-oxygen cycle. It’s used during lab sessions or as a supplemental learning activity to reinforce theoretical knowledge with hands-on (virtual) experimentation. It helps students visualize and understand the interdependence of living organisms. This resource is particularly useful for students who benefit from a visual and interactive learning approach.
**Common Limitations or Challenges**
This document is *not* a standalone learning resource. It requires access to the ExploreLearning Gizmo to be fully utilized. It provides a framework for investigation and data recording, but does not offer detailed explanations of the underlying biological mechanisms. Students will still need to rely on course lectures, textbooks, and other materials to fully grasp the concepts. This preview does not include the full experimental data or completed analysis sections.
**What This Document Provides**
The full document includes:
* Prior Knowledge Questions to assess initial understanding.
* Guided instructions for using the Plants and Snails Gizmo.
* Data collection tables for recording observations about gas levels (oxygen and carbon dioxide) in different experimental setups.
* Analysis questions to prompt critical thinking about the relationship between plants, animals, light, and gas exchange.
* Sections dedicated to exploring the carbon dioxide-oxygen cycle and interdependence.
* Specific prompts for observing changes in water color using bromothymol blue (BTB) as an indicator.
This preview only provides a selection of questions and initial observations from Activity A and B, demonstrating the type of investigation and data analysis expected. It does *not* include the complete set of experiments, data tables, or the fully completed analysis sections.
