Scientific Method Project
By Dr. A. Davila10/20/2010
Problem:
• Does the Sun affect the seasons on planet Earth?
Hypothesis:
• I believe that the sun has nothing to do with the Earth’s seasons.
Materials:• A worksheet to record data collected from the an Internet
valid source• Graph paper to record a broken line graph of the duration
of daylight and darkness.• Graph paper to record a bar graph of the length of
daylight of and darkness.• An internet source to validate the beginnings of each of
the seasons• Flashlight and regular graph paper• Pictures to record the changes that occur on humans and
animals during each season
Procedures:• Daily record the sunrise and sunset data on a worksheet
which was collected from http://www.valleycentral.com/weather/
• Calculate the duration of daylight and darkness, plus record points on a graph paper, every Monday
• Graph the sunrise and sunset on a graph paper that represents the length of a day on planet Earth.
• An internet source to validate the beginnings of each of the seasons (see following slide)
• Pictures to record the changes that occur on humans and animals during each season

Seasons
Results:• My hypothesis was incorrect. The sun does
affect the seasons on planet Earth. However, if the Earth was not tilted the seasons would stay the same at each location.
• For my next project, I would like to research the Earth’s tilt. Is the Earth tilted the same degrees all the time? What could possibly be causing the Earth’s tilt?
