2. The Earth in the Universe
Length of days
FINAL TASK
In this task we suggest you investigate
the differences in the number of hours
of daylight in different times of the year,
in different places in the world, and the
relation with latitude. You will put the results of your
investigation on a poster.
a)
What is the latitude of the capital of your province and the cities of Oslo,
Quito and Sydney?
b)
Which day has the most hours of daylight in each of the locations
investigated? Which day has the smallest number of hours?
c)
At what times of the year is there more difference between the number
of hours of day and night?Which times of the year are they more similar?
d)
How does an increase in latitude affect the length of days and nights?
What happens at similar latitudes in different hemispheres?
e)
What happens in the North Pole during the winter solstice?What happens
during the summer solstice? What happens in the South Pole?
f)
Can you estimate approximately the hours of daylight for the 1st, 11th
and 22nd of this month?
1. Research
Design a poster to present the results of your research:
a)
Organise the information before you choose the main content and think
about the information to include on your poster.
b)
Make a plan to organise the information you are going to put on the
poster. Revise the parts of a poster in UNIT 1.
c)
Write the relevant information for each section and chose suitable
images to illustrate it. Include tables and graphs that you have made.
d)
Try to make your poster attractive and the information clear. Don’t use
the same colours for the text font and the background of the poster.
e)
Make a bibliography of the sources you have consulted.
2. Presentation of results

Follow these steps for your research:
Search for information
❚
Locate the cities studied on a world map. Make a note
of their latitude and the hemisphere each one belongs
to.
❚
Do a search on the Internet to find out the times of
sunrise and sunset in these locations. Use the 1
st
, 11
th
and 22
nd
day of each month as a reference.
Organise the information
❚
Make a table with the times of sunrise and sunset in
each city and make a graph to show how the hours
of daylight vary in each one.
❚
Write the answers to all questions in the
Research
section.
Obtain conclusions and verification
❚
Verify your answers. Confirm that your conclusions
agree with the contents of the unit.
❚
Don’t use only one source of information. Check
that your answers are repeated in different sources.
❚
Check that you have answered all the questions.
