I found the text version!! :)03.03 The Seasons—Formation of Seasons Activity Text Version Introduction Every object in the universe is in motion because of the gravitational forces between them. Our galaxy the Milky Way moves together with the other galaxies. The Sun moves around the center of the Milky Way. And our Earth revolves around the Sun. All of these motions have consequences. For example, the seasons change according to the position of the Earth around the Sun. Introductory Activity Can you guess the position of the Earth around the Sun when it’s summer in New York City? Using the slider, move the Earth to the position you think is correct. Click on the OK button Feedback When the Earth is in this position, it is fall in New York City When the Earth is in this position, it is spring in New York City. When the Earth is in this position, it is winter in New York City. When the Earth is in this position, it is summer in New York City. You can observe the other seasons at different positions of the Earth, or click on the Next button to continue. Part 2 It is commonly thought that the Earth's seasons are caused by differences in its distance from the Sun. In fact, the distance has very little effect on seasons. On the contrary, the Earth is farther from the Sun when it is summer in the northern hemisphere. How can you explain this? While revolving around the Sun, the Earth also rotates on its axis. If Earth rotated on an axis perpendicular to its orbit, over the course of the year the angle of the sunlight falling on the Earth would not change, and we would have only one season. However, the axis the Earth rotates on is tilted to one side. Due to this tilt, the angle of the incoming sunlight changes as the Earth travels around the Sun. While sunlight falls perpendicularly on the equator on March 20, the same light falls perpendicularly on the northern hemisphere on June 21, then again on the equator on September 23, and finally on the southern hemisphere on December 21. Furthermore, the hemisphere that is tilted towards the Sun stays under the sunlight longer and has longer days. The changing lengths of the days, together with the changing angle of the sunlight, affect the amount of heat the Earth receives from the Sun, and thus cause the different seasons to occur. Part 3: Activity In this activity, you will explore how the amount of heat the Earth receives is affected by the angle of the incoming sunlight. A light sensitive plate will represent a place on Earth …and a light source will represent the Sun. You will heat up the plate with light energy released during equal time intervals, and a thermometer will read the changes in its temperature. Directional Information To start heating, turn on the lamp. You can tilt the screen the plate is located on and see how its angle affects the amount of heat the plate receives. Now change the tilt angle of the screen. How does the change in the tilt angle affect the amount of heat the plate receives? Click on the correct answer. Answer A: The plate receives the same amount of heat. Answer B: Increasing the tilt angle increases the amount of heat and decreasing the tilt angle decreases the amount of heat. Answer C: Increasing the tilt angle decreases the amount of heat and decreasing the tilt angle increases the amount of heat. You picked Answer A: The plate receives the same amount of heat. To test your answer, you should tilt the screen with an angle which is to the right of the vertical position of the screen. Your answer is incorrect. As you have seen, changing the tilt angle of the lamp counter clockwise affected the amount of heat the plate received. Increasing the tilt angle counter clockwise caused a decrease in the amount of heat, and decreasing the tilt angle counter clockwise caused an increase in the amount of heat. If you made the same observation clockwise, you would reach the same conclusion. Try another angle which is to the left of the vertical position of the screen You picked Answer B: Increasing the tilt angle increases the amount of heat and decreasing the tilt angle decreases the amount of heat. To test your answer, you should tilt the screen with an angle which is to the right of the vertical position of the screen. Your answer is incorrect. As you have seen, changing the tilt angle of the lamp counter clockwise affected the amount of heat the plate received. Increasing the tilt angle counter clockwise caused a decrease in the amount of heat, and decreasing the tilt angle counter clockwise caused an increase in the amount of heat. If you made the same observation clockwise, you would reach the same conclusion. Try another angle which is to the left of the vertical position of the screen. You picked Answer C: Increasing the tilt angle decreases the amount of heat and decreasing the tilt angle increases the amount of heat. To test your answer, you should tilt the screen with an angle which is to the right of the vertical position of the screen. Your answer is correct. As you have seen, changing the tilt angle of the lamp counter clockwise affected the amount of heat the plate received. Increasing the tilt angle counter clockwise caused a decrease in the amount of heat, and decreasing the tilt angle counter clockwise caused an increase in the amount of heat. If you made the same observation clockwise, you would reach the same conclusion. You can continue to make new observations, or click on the NEXT button to hear the explanation. Conclusion In the experiment we have seen that if light falls directly on a surface, it heats up the surface much more effectively. This is because the total area illuminated by the light increases when the surface is inclined and the intensity of the light received by the plate decreases. Similarly, as the Earth revolves around the Sun, at one point the sunlight falls perpendicularly on the northern hemisphere. At this point, the intensity of the sunlight is the greatest, and the duration of sunlight reception is the longest. So it’s summer in the northern hemisphere, even though the Earth is farther from the Sun. At the very same time, the sunlight falls on the southern hemisphere at an extreme angle. Here, the intensity of the sunlight is the weakest, and the duration of sunlight reception is the shortest. Therefore the southern hemisphere experiences winter. As the Earth continues its motion, the angle of sunlight changes, creating different heating of the northern and southern hemispheres, and resulting in different seasons. You have now completed the goal of this experiment! Please fill out your lab report for submission.
