Use Your Critical Thinking Skills: Now that you have determined the declination of the Sun and daylength for February 16th, May 16th, August 16th, and November 16th, what connection can you make between the declination of the Sun and daylength for these dates? Explain your response in one to two sentences
In the summer, as the sun is closer to the earth(because the earth axis is 23.5degrees tilted ), the daylight will stay longer.
Use Your Critical Thinking Skills: How could farming and other food services be impacted at latitudes with significantly less daylength throughout the year? Explain your response in at least one sentence.
I imagine Farmers use greenhouse with specified lighting to mimic the sunlight in order to grow their plants. Also, countries in the least amount of daylength, can import some necessary plants or goods.
Use Your Critical Thinking Skills: If you lived on or near the equator, do you think it would be valuable for you to use renewable energy (solar and wind) versus nonrenewable energy (gas and oil)? Why or why not? Explain your response in at least one sentence.
Yes, for sure! Living in the equator has great opportunities for me. having solar panels in the roof of my house can satisfy the energy that I want to keep my house warm in the winter, provide electricity, hot water, etc. gas or oil are not clean energies. Also those will not be available forever.so it’s better to switch to renewable energies as soon as we can to help our planet breath.
What is the most important idea that you learned in this lab? In two to three sentences, explain the concept and why it is important to know.
In this lab I learned about how the solar system works and how we are dependent on the sun. I also now can explain why we have different seasons, why the daylength changes, and how the little tilt on the earth position has helped us to survive.
What is one question that you have about what you learned in this lab? Write your question along with one to two sentences explaining why you think your question is important to ask.
My question will be: what are the other renewable energies in the world that we have never found?
Find the latitude of your home city on a map, globe, or the internet. Which of the eight locations listed are you closest in latitude to? Apply What You Learned: Based on what you have learned so far, explain how daylength would vary for your city. Explain your response in two to three sentences.
a:I live in nashville which is located in 36.16 N which is very close to Tokyo in the table b:In my city daylength varies in different seasons. In the summer daylength is longer and in opposite in the winter it is very short.
What was the most challenging part of this lab? In two to three sentences, explain why it was challenging. If nothing challenged you in the lab, write about what you think challenged your classmates.
The most challenging part was to use the SA equation analemma to calculate the sun’s declination.
How does what you learned in this lab relate to your everyday life? In two to three sentences, explain a concept that you learned in this lab and how it relates to your day-to-day actions.
I can now find out why I have to wake up early in winter and leave early from work since the days are shorter..
Use the analemma (Figure 3.9) to determine the Sun’s declination on the following days of the year. Tip: use a ruler or piece of paper to align the date to the vertical axis. January 1: February 16: May 16: July 4: August 16: November 16: Write your birthdate and the Sun’s declination on that date: Which solstice or equinox occurs closest to your birthdate?
G-April 17 H- March equinox
Refer to your completed Figures 3.11 through 3.14. Which latitude has the highest angle of incidence year-round? Which latitude has the lowest angle of incidence year-round? In one sentence, describe how the angles of incidence change throughout the year for the Tropic of Cancer. Apply What You Learned: When would the radiation intensity be highest for the Arctic Circle?
A-Equator B-arctic and Antarctic C-Tropic of cancer follows a year cycle from 90 degrees which is from directly overhead to December solstice and it goes back again. D-during summer.
Apply What You Learned: Imagine that you want to install a solar panel at your latitude. At what angle(s) would you orientate the solar panel in order to maximize the amount of radiation that is received? Would you install the solar panels in a stationary position, or would you allow for the solar panels to move throughout the year? Explain your response in two to three sentences. Tip: estimate the angle of incidence at your latitude based on the data provided in Table 3.1. Hint: it may be easiest to sketch the surface of the Earth, your solar panel, and the estimated angle of incidence in order to respond to these questions.
I would definitely install it the way that sunlight hits the most on the surface which is 90 degrees. I would not install it stationary because I want it to use the maximum of energy the whole time that the sun is in the sky.
Use the information from Table 3.2 and draw the Sun in its correct place in the sky for each of the following four dates: April 8th, July 17th, October 31st, and December 7th. Use Figure 3.16 as a model for your diagrams and write captions with the same information shown in Figure 3.16. April 8th: July 17th: October 31st: December 7th:
A: Top B: Right C: Bottom D: Bottom
Refer to Table 3.3. Use Your Critical Thinking Skills: Why does Table 3.3 have a specific location for 60°N but no location for 60°S? Hint: look at a globe, an atlas, or Google Earth! Use Your Critical Thinking Skills: If a specific location had been provided for 60°S, would daylength at that location be similar to the daylength for 60°N? Explain why or why not in one to two sentences. Other than the poles, which of the eight locations has the greatest variation in daylength throughout the year? Explain why in one to two sentences. Tip: for each location, subtract the largest daylength number from the smallest to find the variation in daylength at that latitude. Other than the equator, which of the eight locations has the least variation in daylength throughout the year? Explain why in one to two sentences. Canberra and Tokyo are both located at a general latitude of 35°, however, their daylengths are different from each other on each of the four dates. Explain why in one to two sentences. On which date(s) does Palmas have a longer daylength than the equator? What are the seasons of these dates for Palmas? Does the equator have seasons? Why or why not?
a: the globe shows the South Pole plus ocean. No specific land exist in that area. b: no they have different daylength due to planet earth tilt. c: based on the numbers in the table of eight locations, greatest variation in daylength is white horse, Canada 60 degrees north due to the earth position to the sun. d: according to the table, Quito, Equador 10 degrees south has the east daylength variation. e: as I mentioned in the previous answers, the position of the earth to the sun makes the daylength to be different. f: February 16 and November 16 Palmas has longer daylength. Fall and Winter. g:No, beacause the equator always remain in the center.
Refer to Figure 3.10. Does the flashlight on the left or right represent a 90° angle of incidence? (Hint: a 90° angle of incidence is also known as a direct ray or a perpendicular ray.) Does the higher or lower angle of incidence result in the flashlight’s energy being distributed over a wider area?
A-No B-yes
