Part 4: Conducting the Experiment and Applying Results

Work Format
Complete all parts of this section in your science notebook or digital document.

  1. Prepare for Data Collection 
    Before you begin your experiment: 
    • Copy and use the data table you designed in your lab proposal. 
    • Revise or improve your table if needed. Include a descriptive title, labeled columns, and units. 
    • Ensure there is a column added for qualitative observations
    • Confirm that you have all required materials and equipment ready for your experiment 
    • Review your procedure to ensure all variables and conditions are consistent. 
  2. Conduct the Experiment
    • Carefully follow the approved procedure of your lab proposal.
    • Take photos or short videos of your setup for your presentation.
    • Keep all conditions consistent across trials.
    • Record all data accurately in your table.
    • Note any adjustments, errors, or challenges during testing.
    • Repeat trials as needed if results are inconsistent.
  3. Analyze and Interpret Data
    After completing your experiment, use your data to answer your research question. 
    • Explain what the data shows about the variable you tested. 
    • State whether your results support or reject your hypothesis.
    • Calculate averages, percent changes, or efficiency differences as needed to show overall trends clearly. 
    • Organize your data using consistent units and labels.
  4. Visualize Results
    Create a graph to display your data. 
    • Choose an appropriate graph type (e.g., line graph for continuous data, bar graph for categories, etc.).
    • Label both axes (with appropriate units) and include a clear title.
    • Graph processed data (e.g., averages), not every trial.
  1. Identify Trends and Evaluate Results
    • Describe patterns in your data (e.g., increase, decrease, plateau). 
    • Identify any unexpected results. 
    • Discuss possible sources of error.
    • Explain how your experiment can be improved.
  2. Apply Findings to Your Solar Design
    Use your results to inform your solar array design.
    • How do your findings affect panel size, tilt, or placement? 
    • What constraints or limitations did your data reveal? 
    • How do your results support or challenge your original assumptions?
