Why it's a good idea: This topic is directly relevant to water resource management. You can collect water samples and analyze them for various pollutants.
Methodology: Collect water samples from different locations along the river/stream, representing different land use types. Analyze the samples for parameters like pH, dissolved oxygen, nutrient levels, and heavy metals.
Links to the Rubric: This investigation allows for a clear and focused research question (Criterion A). A well-defined research question that directly addresses the environmental issue will earn you high marks.
7. The Effect of Acid Rain on Plant Growth
Research Question: What is the effect of simulated acid rain (at varying pH levels) on the germination rate and growth of [Specific Plant Species]?
Why it's a good idea: This is a classic environmental science experiment that can be easily adapted for the IA.
Methodology: Germinate seeds and grow plants in controlled conditions, exposing them to simulated acid rain at different pH levels. Monitor germination rate, plant height, and biomass.
Links to the Rubric: This investigation allows for a replicable method (Criterion C). Clearly describe the setup, the preparation of the acid rain solutions, and the data collection process.

Common Challenges/Mistakes Section
- Unclear Research Question: A vague or overly broad research question makes it difficult to design a focused investigation. Solution: Refine your research question to be specific, measurable, achievable, relevant, and time-bound (SMART).
- Poor Methodology: A poorly designed methodology can lead to unreliable data and invalid conclusions. Solution: Consult with your teacher and research established methodologies for similar investigations. Ensure your method is replicable and allows for sufficient data collection.
- Inadequate Data Analysis: Failing to properly analyze your data can prevent you from drawing meaningful conclusions. Solution: Learn basic statistical analysis techniques and use appropriate software (e.g., spreadsheets, statistical packages) to analyze your data.
- Ignoring Limitations: Failing to acknowledge the limitations of your investigation can weaken your evaluation. Solution: Be honest about the limitations of your methodology and discuss how they might have affected your results.
- Lack of Connection to ESS Concepts: Failing to connect your investigation to core ESS concepts can lower your score. Solution: Explicitly link your findings to relevant ESS topics, such as sustainability, biodiversity, pollution, and resource management.
Advanced Tips/Strategies Section
- Focus on Local Issues: Investigating a local environmental issue allows you to collect firsthand data and make a real-world impact.
- Combine Quantitative and Qualitative Data: Using both types of data can provide a more comprehensive understanding of the issue.
- Consult Scientific Literature: Research existing studies on your topic to inform your methodology and analysis.
- Seek Feedback from Your Teacher: Regularly consult with your teacher for guidance and feedback throughout the investigation process.
- Start Early: Don't wait until the last minute to start your IA. Give yourself plenty of time to plan, conduct your investigation, and write your report.
