For your experiment, it's important to systematically gather and evaluate data on how each type of plastic reacts over time. Here’s a structured approach to collecting data:
Data Collection Structure
-
Observation Table: Create a table with the following columns to track your observations over the duration of the experiment:
| Day | Plastic Type | Observations (e.g., cracks, discoloration, pieces broken off) | Photos (If applicable) | |-----|------------------|--------------------------------------------------------------|-----------------------| | 1 | Bottle | | | | 1 | Yogurt Container | | | | 1 | Foam Box | | | | 4 | Bottle | | | | 4 | Yogurt Container | | | | 4 | Foam Box | | | | 7 | Bottle | | | | 7 | Yogurt Container | | | | 7 | Foam Box | | | | 10 | Bottle | | | | 10 | Yogurt Container | | | | 10 | Foam Box | | | | 14 | Bottle | | | | 14 | Yogurt Container | | | | 14 | Foam Box | | |

Data Points to Measure:
- Physical Appearance: Note any visible signs of degradation such as cracks, discoloration, or peeling.
- Size Changes: Use a ruler to measure and note any changes in size or dimensions of the plastic samples (if applicable).
- Fragmentation: Count and describe how many pieces the plastic sample has broken into over time.
- Weight Changes: If you have access to a scale and can measure before and after, note any weight difference (though this can be challenging practically).
- Photos: Take photos at regular intervals to visually document any changes.
-
Analysis:
- After the observation period, compare the results for each plastic type.
- Summarize your findings by noting:
- Which plastic showed the most signs of degradation?
- Which plastic remained relatively unchanged?
- Insightful details based on your observations (e.g., "The foam box showed no visible changes, suggesting it is more resilient to degradation in these conditions").
- Consider any external factors that might have influenced your results (e.g., sunlight intensity, initial conditions of the plastic, etc.).
-
Conclusion:
- Analyze the overall data and draw conclusions about the persistence of different types of plastic in marine environments.
- Discuss implications for environmental issues, particularly plastic pollution.
Final Report:
Compile your observations, analysis, and conclusions into a final report or presentation format. You may include visual aids like charts or graphs summarizing your findings. This structure will help you present your data clearly and effectively!
