    Study Notes

    Scientific Investigation

    • A scientific investigation is a systematic approach to answer questions about the world around us.
    • The number one component is to formulate a specific question or problem to be tested.

    Formulating a Hypothesis

    • A hypothesis is a statement that gives a tentative answer or solution to the question.
    • It is the expected outcome in an experiment.

    Selecting and Justifying a Procedure

    • This step involves formulating procedures for the actual experiment.
    • Procedure examples:
      • Write hypothesis in a testable form.
      • Identify the variables that need to be controlled for a fair test.
      • Identify the dependent and independent variables.
      • Prepare all the materials needed.
      • Make experimental and control setup.

    Identifying Variables

    • Identify the dependent and independent variables in the investigation.
    • The independent variable is the variable that stands alone and cannot be affected by the other variable.
    • The dependent variable is the variable that depends on the independent variable.

    Carrying Out the Procedure

    • This step involves performing the experiment, including a fair test.
    • A fair test is making sure that in an experiment, one factor or condition (the independent variable) affects another (the dependent variable) by keeping all other conditions constant.
    • Control variables are factors that are kept the same in both the experimental and control setups.

    Making Observations

    • The focus of observation is the dependent variable.
    • In this case, the observation is the plant growth.

    Making Measurements

    • Choose appropriate devices and units for measurement.
    • In this experiment, the device is a tape measure or ruler, and the unit is centimeter.

    Recording and Reporting

    • Record the measurements of plant growth in a certain period of time.
    • Use charts or graphs to record and report the data.

    Interpreting Data

    • Use graphical representation such as bar graphs, line graphs, and pie charts to interpret data.
    • Write the interpretation of data in the chosen graph.

    Drawing a Conclusion

    • Draw a conclusion from the results obtained, including a statement to support or reject the hypothesis.
    • The conclusion should be supported by citing studies and experiments with similar results.

    Scientific Investigation

    • A systematic approach to answer questions about the world around us, with a specific question or problem to be tested.

    Formulating a Hypothesis

    • A statement that gives a tentative answer or solution to the question, expected outcome in an experiment.

    Selecting and Justifying a Procedure

    • Formulating procedures for the actual experiment, including:
      • Writing hypothesis in a testable form.
      • Identifying variables to be controlled for a fair test.
      • Identifying dependent and independent variables.
      • Preparing materials needed.
      • Setting up experimental and control setups.

    Identifying Variables

    • Identifying dependent and independent variables:
      • Independent variable: stands alone and cannot be affected by the other variable.
      • Dependent variable: depends on the independent variable.

    Carrying Out the Procedure

    • Performing the experiment, including a fair test, by:
      • Keeping all other conditions constant.
      • Identifying control variables: factors kept the same in both experimental and control setups.

    Making Observations

    • Focusing on the dependent variable, in this case, plant growth.

    Making Measurements

    • Choosing appropriate devices and units for measurement, such as:
      • Tape measure or ruler.
      • Units: centimeters.

    Recording and Reporting

    • Recording measurements of plant growth in a certain period of time, using:
      • Charts or graphs.
      • Recording and reporting data.

    Interpreting Data

    • Using graphical representation, such as:
      • Bar graphs.
      • Line graphs.
      • Pie charts.
      • Writing interpretation of data in the chosen graph.

    Drawing a Conclusion

    • Drawing a conclusion from the results, including:
      • Statement to support or reject the hypothesis.
      • Citing studies and experiments with similar results.
