Page 2: Scientific Method Project By Dr. A. Davila 10/20/2010

Problem:

• Does the Sun affect the seasons on planet Earth?

Page 3: Scientific Method Project By Dr. A. Davila 10/20/2010

Hypothesis:

• I believe that the sun has nothing to do with the Earth’s seasons.

Page 4: Scientific Method Project By Dr. A. Davila 10/20/2010

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

Page 5: Scientific Method Project By Dr. A. Davila 10/20/2010

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

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?
