Step-by-Step Procedure

  1. 1

    Cut the top off the plastic bottle to create a funnel.

  2. 2

    Inverted the top part into the bottom half to catch rain.

  3. 3

    Secure the rain gauge in an open area away from obstructions.

  4. 4

    Use the ruler to mark measurements on the side of the bottle.

  5. 5

    Record rainfall measurements daily.

  6. 6

    Analyze the data to observe rainfall patterns.

  7. 7

    Create a graph showing total rainfall over time.

  8. 8

    Prepare a presentation summarizing your findings.

Expected Results

You should successfully measure and track rainfall amounts over time, visualizing the data through graphs.

Variables

Independent Variable

Time period of measurements

Dependent Variable

Amount of rainfall measured

Controlled Variables

Location of the rain gauge, Measurement intervals, Weather conditions

Safety Notes

Ensure safe handling of scissors when cutting the bottle and secure the rain gauge to prevent it from blowing away.

Presentation Tips

  • Display graphs showing rainfall trends.

  • Include photos of your rain gauge in action.

  • Explain how rainfall measurements impact water resources.

  • Engage your audience with questions about their rainfall experiences.
