Interpreting Data

  • Understanding and interpreting data is crucial for a successful experiment

    • It helps confirm if your findings agree or disagree with your initial hypothesis

  • This process gives meaning to the information or data that has been collected and helps identify why it’s important

    • Sometimes, the data might only partially support the initial hypothesis

Scientific Method Limitations

  • Scientific experiments and investigation often present challenges that make it tough to get reliable data

    • These challenges come from things like how the research is set up, the materials used, the methods followed, and dealing with limited time and money

    • Common problems include issues with the sample, its size, and difficulties with the tools, instruments or methods used for collecting information

    • These factors can all contribute to unreliable data and uncertainty in the results

    • Limitations of environmental research can include:

      • Challenges accessing remote or hazardous locations for repeated data collection

      • Unpredictable weather

      • The difficulties of sorting and organising samples when out in the field

  • It’s important that scientists clearly communicate the challenges they face during their research and suggest ways to improve or fix them

  • Other challenges to collecting reliable data can include:

    • Human error: when the researcher makes mistakes e.g. miscounting the number of oxygen bubbles produced by an aquatic plant as photosynthesis occurs

    • Researcher bias: scientists might expect a certain answer and focus only on that, which can make them miss other information that could give a different result – being aware of and reducing these biases is crucial for fair and accurate science

Scientific Theory

  • A robust scientific hypothesis, backed by substantial data, can progress into a scientific theory

    • For example, the initial hypothesis that deforestation reduces biodiversity has now evolved into a theory with a huge amount of supporting evidence

  • Theories serve as the basis for predictive models, enabling scientists to predict outcomes in different environmental scenarios

    • For example, theories about habitat size and fragmentation can now help environmental scientists to predict the consequences of continued deforestation on biodiversity

  • It is important to note that scientific theories are not fixed

    • They have the flexibility to adjust and transform as new data emerges

    • This adaptability ensures that theories stay accurate, reflecting the latest understanding of environmental processes
